map roman empire crisis of the third century

In 235 the Crisis of the Third Century began with the assassination of the last of the Severan dynasty, a crisis that weakened and changed forever the Roman Empire. Emperors and wannabe emperors were continuously proclaimed causing a constant state of civil war, Rome was threatened by external enemies like the Germanic tribes or the Sassanid Empire in the east, plagues reappeared and crippled the population, and all that of course had very negative economic effects. Commerce declined as there were no safe roads or safe maritime trade routes, cities suffered from both plagues and economic depression and that ended the tendency to urbanize and instead there was a tendency to go back to small rural communities. Rome based their economy in the military expansion to capture slaves, spoils of war and new lands for the landowner class. But expansion could hardly continue, and the military apparatus was expensive to maintain. Moreover, as there were less slaves, they became more expensive, so landowners stopped using slaves and instead used farmers who paid landowners for leasing their land to farm it and for protection. That was the germ of feudalism, because free farmers lost their freedom to move to other lands and their condition of semi-slavery was hereditary.

That was what was happening all over the Roman Empire, but what was happening in Hispania? The negative consequences of the Military Anarchy weren’t as obvious in Hispania as in other regions. The reason behind it is that Hispania was already in economic decline during the reign of the Severan dynasty. But outside of the economic crisis and social changes, Germanic tribes entered for the first time the Iberian Peninsula. In 258 thousands of Franks and Alamanni from Germany penetrated into Gaul. They devastated and sacked everything in their path. Hispania had enjoyed peace for more than a century as battles of civil wars occurred in other regions, so cities weren’t properly fortified. Knowing that Hispania could be the next target of the Franks, some cities were able to build fortifications that, because of the hurry, weren’t very solid. Worse was that ever since the Severan dynasty few Hispano-Romans joined the army. The Franks eventually crossed the Pyrenees and razed the Mediterranean coasts of Hispania. They destroyed and left in ruins Emporion, Girona, Lleida, Tarragona, Zaragoza and everything in between. Hispania Baetica resisted effectively the invasion, either because they built fortifications after the Berber raids of previous decades or because Postumus intervened. Who is this Postumus, you wonder? Postumus was the Roman governor and general of the Roman forces of Germania. In 260 he was tremendously successful in repelling new waves of Franks who were trying to invade the Roman Empire. In a time of chaos, many saw on him the leader that could ensure their protection and survival. Postumus quickly established the breakaway Gallic Empire, that controlled Gaul, Germania, Britannia, and, for some time, Hispania. Let me clarify this, historiography considers that Postumus created a separate state because he didn’t attempt to conquer Italy and he created institutions that emulated the Roman ones.

Anyway, going back to the point, a military aid from Postumus in 265 or 266 would explain the brief allegiance Hispania showed to the Gallic Empire. The Franks who were in Hispania either had a miserable destiny or fled to Mauritania. Emperor Aurelian reconquered the Gallic Empire in 274, as he did with the Palmyrene Empire of the east. That earned him the title of Restorer of the World, but that didn’t last long. He was assassinated the following year, which made the Roman Empire vulnerable to external threats again. In 276 thousands of Franks and Alamanni invaded Gaul and a few raided Hispania, although presumably not with the devastating magnitude of the previous one. This time they raided Northern Spain, sacking Pamplona, Astorga, Mérida, Lisbon and rural areas too.

Hispano-Roman cities rebuilt their walls and created local militias, but it was too late. Some cities were able to rebuild, some could not, but what all cities had in common is that they lost population. To have better chances of survival many started moving back to the countryside. People in those times of uncertainty moved back to the countryside to avoid plagues and to reduce the odds of suffering an attack from barbarian invaders. The basic pillar of the Roman Empire was the municipality, and municipalities kept disappearing or losing importance. Valuable Spanish industries like olive oil farming, mining or salting diminished their production. It’s very indicative of a loss of purchasing power that there are no pieces of art dating from between 260 and 280. The economy became less market-oriented and more agrarian and local. Europe was one step closer to feudalism.

In this era of desperation, a new religion spread to bring some hope: Christianity. As you know, Spain and Christianity eventually became very tied concepts, so let me dedicate some time to the origins of Christianity in Hispania, how it expanded and the heresies and martyrs of Spain. Before we talk about Christianity, we must talk about the Jewish community of Hispania. We’ve very few literary references about Jews in the Iberian Peninsula before the 4th or 5th centuries. We have some archeological evidence that confirms the presence of Jews in Hispania at least since the 1st century, but judging from the quantity of findings there weren’t many Jews. Why do I bring this up? Well, the followers of Christ were considered a Jewish sect until the 2nd century. It was only then that Christianity became a clearly different thing that competed against Orthodox Judaism as both religions wanted to proselytize. If there weren’t many Jews in Hispania, it makes sense that Christianity took more time to arrive and establish itself.

The ecclesiastical historiography has always made an effort to prove the apostolic origin of Spanish Christianity, based on three independent traditions: the preaching of Apostle James the Greater, the preaching of the Seven Apostolic Men and the arrival of Paul the Apostle. The preaching of James the Greater has no historical basis, because it wasn’t until the 9th century that we have accounts claiming that Apostle James the Greater was buried in Santiago de Compostela. Yeah, we don’t have historical justification for the Camino de Santiago, but this legend helped to boost the morale of the Christians during the Reconquista. Even today James the Greater is the patron saint of Spain and the Spanish armies used for centuries the battle cry “Santiago y cierra España”, which means Saint James and strike for Spain. The second tradition I mentioned was the preaching of the Seven Apostolic Men, who were seven clerics sent to evangelize Spain. Again, it’s only many centuries after the event supposedly happened that we have news of them, so it’s very unlikely that they existed.

Nonetheless, the third tradition about the arrival of Paul the Apostle could be true. Saint Paul wrote in his Epistle to the Romans that he willed to travel to Hispania and start proselytizing. His will isn’t a confirmation that he actually travelled to Spain, but according to Pope Clement I Paul preached the Gospel of Christ to the edges of the West, a sentence that unquestionably refers to the Iberian Peninsula. There are other mentions of this travel in other early Christian texts as well. The question that arises from it is why there would be a discontinuation between Paul’s preaching and the later Spanish Christianity, something that did not happen in the other places he proselytized.

Whatever is the truth behind the arrival of Paul the Apostle in Hispania, the most widely accepted and corroborated theory is that Christianity in Hispania came from Africa. Both the military and commerce with Africa had a very important role in the expansion of Christianity. The Legio VII Germina was moved from North Africa to northern Spain, using the Vía de la Plata that connected Mérida with Astorga in Asturias. That would explain why the churches of Mérida, Astorga and also Zaragoza, the capital of modern Aragon, appealed to the bishop of Carthage to solve an issue instead of Rome in 254. It’s good to remind that Early Christian churches were very independent from each other, but the appeal to Carthage would demonstrate a relationship that Spanish churches didn’t have with Rome. There are other evidences that reinforce the veracity of this theory. The Synod of Elvira, in modern-day Granada, mentions characteristics that could only be found in North African churches. Besides, the liturgy and the architecture of the firsts Spanish churches have strong North African characteristics.

About persecutions against Christians, we don’t have news of any in the 1st or 2nd centuries. The first Christian persecution that affected Hispania was ordered by Decius in 250. A major persecution was ordered by Valerian and some important priests of the Spanish Church were affected. For instance, the bishop of Tarragona Fructuosus and deacons Augurius and Eulogius were sentenced to death by burning in 259. Diocletian had the dubious honor to be the last Roman emperor to persecute Christians, and in Hispania many became martyrs because of him.

However, it was also Diocletian the man to reform the empire to end the Crisis of the Third Century. His reforms consisted in the division of the empire into the Western and Eastern Roman Empires and the centralization of power, expanding the bureaucracy of the empire and ruling more autocratically than ever. Diocletian doubled the number of provinces of the empire to make them easier to manage and to reduce the power of provincial governors.  Hispania specifically had the province of Hispania Tarraconensis divided in three: Hispania Gallaeica, Hispania Carthaginensis and a smaller Hispania Tarraconensis. To control and coordinate provincial governors Diocletian created dioceses that grouped several provinces. The Diocese of Hispania not only grouped the provinces of Hispania but also Mauretania Tingitana, modern Morocco.

Aside from the administrative reforms, Hispania experienced economic and urban changes. Hispania was one of the first regions of the Roman Empire to partly recover its former economic importance. Of course, Hispania did not completely recover until many centuries later with the Emirate and Caliphate of Cordoba, but at least people didn’t live fearing attacks or suffering massive epidemics. Hispalis, modern Seville, became the most important city of Hispania, due to the flourishing waterway transportation of goods of the Guadalquivir Valley, like olive oil, wine, horses or Serrano ham. Barcelona gained importance as Tarragona never recovered from the destruction the Germanic invaders caused, and Cádiz also declined in importance. On another note, brigandage was rampant in the countryside, with special importance in the Pyrenees and Northern Spain. This phenomenon was called bagaudae and it was not just brigandage but a revolutionary movement against the upper classes as well, led by groups of impoverished peasants, runaway slaves and army deserters. The crème de la crème of society, right? They were more or less subdued in the late 3rd century, but bandits continued to cause problems for centuries.

With the abdication of Diocletian, a new civil war started to seize power. Man, it’s like if they wanted their empire to fall. Constantine emerged as victor in this conflict and reunified the empire. Constantine moved the imperial capital to Byzantium in 330, renaming the city Constantinople, a decision that ensured the survival of Rome in a different form until the Late Middle Ages. More importantly for us, he proclaimed the Edict of Milan in 313 that ordered the toleration of Christianity across the Roman Empire. The Synod of Elvira is contemporary of the Edict of Milan, and I would like to analyze a bit the text of this synod to understand the influence of the Church in Hispania in the early 4th century. The texts left by this synod reveal that Christianity had a strong presence in the cities and especially in the most urbanized region of Hispania, the Baetica. We can also conclude that Christianity had followers from every social class, from oligarchs to slaves. Churches in Spain had enough power to start condemning some jobs and behaviors, and the Christian Hispano-Roman leaders showed concern in relation to the competing Judaism. Even though the Edict of Milan tolerated Christianity, the process of gaining followers wasn’t easy, and in the less-Romanized Asturias, Cantabria and Basque Country, Christianity had a hard time expanding.

After the death of Constantine, guess what happened? Yeah, chaos came back to the Roman Empire. Numerous civil wars and usurpations took place between 337 and 394. Yes, during more than 50 years the empire was in chaos, again, after the disastrous Crisis of the Third Century. I could name all the usurpers and pretenders, but you know, there’s few relevant political stuff from this period, aside from the fact that the Roman Empire was dooming itself. On the religious side though, interesting things were happening. The declining Roman institutions were being replaced by Christian churches that had a capacity to work on a local level that Rome didn’t have.

The faith in the Gospel of Jesus kept expanding, but with the lack of a strong central Church and with the discontentment of some against the increasingly wealthy hierarchies of Nicene Churches, numerous heresies raised as well. In Hispania we have the case of Priscillianism, a Christian movement with characteristics derived from Gnosticism and Manichaeism that promoted a strict ascetic lifestyle. The word of the Hispano-Roman Priscillian expanded in the 370s, and the Synod of Zaragoza in 380 and the First Council of Toledo condemned Priscillianism and showed the increasing political confluence of the religious power with the secular power. The dream of a new fair and more egalitarian social order that Jesus talked about was dead. Priscillian was executed in 385, but his doctrine was stilled followed by many in Hispania and Gaul until the 6th century.

There was little to be saved when Theodosius became the last emperor of the unified Roman Empire and the last Hispano-Roman emperor. Theodosius made Nicene Christianity the official and sole religion of the Roman Empire, any other religion or heresy was banned. Theodosius recognized that many Roman citizens, including himself, had converted to Christianity between the 3rd and 4th centuries, and it made sense to consolidate a political alliance with the Church, a Church that had the Hispano-Roman Damasus as its Pope. During his rule he persecuted paganism, heresies and other faiths, and he tolerated or encouraged the destruction of pagan temples. To mention a specific event that shows how powerful was the Church at this point, Ambroise, bishop of Milan, refused to let Theodosius enter his church until he showed remorse for the Massacre of Thessalonica, a tragic massacre of 7,000 people ordered by Theodosius. If you have watched Game of Thrones, you may see a parallelism with this and how the High Sparrow humiliated Tommen and Cersei in public.

His decision to allow barbarian Germanic peoples to settle in Thrace, very close to the heart of the Roman Empire, has been a matter of controversy for centuries. That certainly was a policy that demonstrated how weak the empire was at the time, but did he have another possible choice? Probably not. While the Huns were massacring Germans, Germans were forced to move to the Roman Empire. They started filling the ranks of the Roman army, to the point where most of the Roman army was Germanic. I mentioned that Theodosius was the last emperor of the unified Roman Empire, but why he decided so? Theodosius knew that if he tried to appoint a sole successor civil wars would continue, so instead he opted to divide the empire once and for all.

In the West Honorius succeeded Theodosius at the age of 10 in 395. For obvious reasons, the one who was actually ruling the Western Roman Empire was a regent, Stilicho, a general with both Roman and Vandal ancestry. This and the fact that most of the Roman army was German proves how decadent Roman society was at this point. I mean, if your own citizens refuse to serve and defend the country, your state sooner rather than later will fall. I will talk about his rule and that of his successors in upcoming episodes, but spoiler alert, the Western Roman Empire won’t survive the 5th century.

I can’t end this episode without talking about the legacy Rome left in Spain. As you know, the Roman Empire was the most solid foundation of Western civilizations that later expanded to America and beyond. To start with, Romans left the Roman laws that developed the framework that the majority of legal systems use today. Then of course Latin became the common language and lingua franca of the empire. Latin survived the empire and was still used in intellectual, cultural, theological and scientific works for centuries. The common people kept using Latin but it eventually evolved into multiple European languages. In the Iberian Peninsula all languages except for Basque derive from Latin, including Spanish, Portuguese, Catalan or Galician. Today 1/3 of the world’s population speaks a language derived from Latin, with Spanish being the third most spoken language after Chinese and English.

Continuing with the cultural legacy, Romans left an amazing artistic legacy that they pretty much copied from the Greeks, with idealistic and narrative sculptures, paintings and mosaics. There were prominent Hispano-Roman writers, playwrights, poets and philosophers. We have Seneca the Elder and the Younger, Lucano, Martial, Columella, Orosius… The existence of a Mediterranean Empire allowed an intercultural and religious exchange that wouldn’t have happened otherwise. Under the Roman Empire the Roman polytheist faith expanded, but also Egyptian, Syrian, and other Oriental beliefs. Eventually that also helped in the expansion of Judaism and Christianity, even if the Roman elites were opposed to these monotheists faiths that challenged their political system. It’s difficult to imagine all these religions expanding if Europe, Africa and Asia had had different rival states.

Then we have a more material legacy. Here I’m going to comment public works and monuments that are still standing in Spain, so if you travel to Spain I highly recommend you to visit a few sites I’m going to mention. You have the script of the podcast in the website if you want to see photos or have all the names written down. That said, the Romans were very pragmatic people, that’s why they were great engineers and they heavily invested in public works to connect the empire. We have the system of Roman roads that allowed to move troops, people and goods in Hispania and beyond, that’s why we have this proverb that says that All roads lead to Rome. It’s very unlikely that the empire would have survived as long as it did without such a network of roads. During the Middle Ages and until the 18th and 19th centuries no one in Europe invested in constructing and maintaining roads as the Romans did. Many highways in Spain go over the old Roman roads, although there are still some visible remnants of Roman roads here and there. To provide water to sustain urban populations they built aqueducts that were incredible works of civil engineering. We have the aqueducts of Segovia, Les Ferreres Aqueduct in Tarragona, or the Aqueduct de los Milagros in Mérida, Extremadura.

The Romans built amphitheaters for spectacles and sports, like the amphitheaters of Santiponce, Mérida, Tarragona or Segóbriga; and theaters for plays like the theaters of Mérida, Málaga, Medellín or Zaragoza. There is also a substantial amount of Roman bridges, the problem is that in the Medieval or Early Modern Era many needed to be reformed and restored, so it’s difficult to tell how Roman they are now. We have the Roman bridges of Córdoba, Mérida, Salamanca or Alcantara. The same that happened with bridges happened with Roman walls and many Medieval walls have a Roman origin. You can visit the walls of Zaragoza, Tarragona or the Portal del Bisbe in Barcelona that is the only door preserved from the original Roman walls. We have a few Roman pagan temples or temples dedicated to the cult to the emperor, like the Temple of Diana in Mérida, the temple of Vic or the four columns of the Temple of Augustus that are still standing in Barcelona.

Romans loved public baths too, not only for hygienic purposes but also to chat and do business. There are not too many relevant rests of Roman bathhouses, but to mention a few, there are the Roman baths of Lucentum in Alicante, Lugo, Segóbriga or Caldas de Montbui. On the other hand, rural villas are very useful to study the lifestyle of wealthy Roman landowners and to contemplate the luxury of their buildings. If you had to visit one Roman villa in Spain you should visit the villa of La Olmeda in Palencia, but you could also visit Fuente Álamo in Puente Gentil, Córdoba, or Almenara in Puras, Valladolid. But apart from all the infrastructures and buildings I mentioned, there are other buildings and monuments that I can’t leave out from this episode. The first would be the Proserpina and Cornalvo dams that were used to ensure the supply of water of Mérida. Then we have the Roman arch of Medinaceli and the arch of Berá, but these arches aren’t as extraordinary as others you can find in Italy, France or Algeria. To end this list, we have the Mines of Las Médulas in León, where the Romans left an impressive landscape with their method to extract gold, and the Tower of Hercules in Galicia, which is the oldest Roman lighthouse still in use today. If you can only go to a few places, the first on the list is of course Mérida, but Zaragoza, Santiponce or Tarragona also have very remarkable Roman archaeological sites.

THE VERDICT: In today’s verdict I want to bring up this question: is history cyclical? Does history repeat itself? Ancient historians like Thucydides in Greece or Sima Qian in China believed so, and there are many modern theories that stand up for historic recurrence, like social cycle theory or the Strauss-Howe generational theory. I bring this up because some see parallelisms in the contemporary decline of the West with the decadence of the Late Roman Empire, even though the world at that time was very different from the current era we live in. I don’t want to enter the eternal debate of whether history is linear or cyclical, instead I want to encourage you to look up information from both perspectives. Something is clear though, unless we evolve biologically, human nature will not change and similar events will occur in new historical contexts. And with that, The Verdict ends.

In episode 10 I will talk about the first Barbarian invasions of the Iberian Peninsula, with the Suebi, Vandals and Alans, and from then on, I expect to cover each period of the history of Spain more deeply.

I’m David Cot, host of The History of Spain Podcast, and this is episode 8, called Hispania: Principate and Romanization. In this episode you will learn the political and economic history of Roman Spain up to the Crisis of the Third Century, as well as the process of Romanization. Subscribe to the podcast to not miss an episode!

Okay, some of you may wonder what Romanization means. Romanization was the process of acculturation of the populations incorporated into the Roman Republic and later Empire. Nonetheless, Romanization was not a deliberate or conscious policy that attempted to eradicate indigenous cultures, and it was not a totally one-sided thing. It was a spontaneous and gradual phenomenon that resulted from the interaction and integration of Roman and native cultures. Cultures change and the Roman culture prior to the Second Punic War is different from the one of, say, the 1st century AD. In Hispania, Roman and indigenous elements blended together and formed the Hispano-Roman culture. Of course the Roman elements predominated, but characteristics of indigenous cultures remained or adapted to look Roman. This syncretism is exactly the same that happened later when Spain colonized America. Yes, Spanish culture predominated, but indigenous elements prevailed as well and new regional cultures emerged from the fusion of Spanish and native cultures.

But what aspects did Romanization cover? Language, religion, customs, material culture and technology, law and urbanism. Let’s start with language. Latin became the lingua franca of the Roman Empire, it was first adopted by the upper classes of Hispania to communicate with both the Roman administration and other tribes. Many natives of the elite sent their kids to Rome to learn the language and to get to know influential people. As you can see, it was in their best interest to adopt Latin. The poor didn’t receive a formal education, yet the language eventually spread from the top to the bottom of the society. By the late 1st century AD all native languages, except from Ancient Basque, had disappeared.

capitoline triad

Another important aspect of Romanization is religion. As you may remember, in Pre-Roman Spain there were many religions, and foreign religions had already influenced the natives before the Romans came. I’m talking about the Phoenician and Greek deities, that could and were easily adapted to those of Rome. As many of you know, Rome essentially changed the names of Greek deities and made them as their own. Yes, they were not very original. Iberians quickly embraced Roman religion during the Late Republic and Early Principate, although that didn’t exclude the possibility of believing in other deities. The most important deities were those of the Capitoline Triad, that is Jupiter, the god of gods; Juno, the goddess that protected the empire; and Minerva, the goddess of wisdom. On the other hand, Iberians quickly adopted imperial cult, as I mentioned in the episode about the Pre-Roman peoples of Iberia Iberians had this social institution called devotio that connected strongly the patron and client, and imperial cult was just an evolution of that. Even when Augustus was still alive, the Spanish cities of Tarragona and Mérida built altars and later temples in his honor. Oriental beliefs, like Syrian, Egyptian, Phoenician or Persian gods had their followers in Hispania too, while Christianity didn’t expand into Hispania until the 3rd century. But we will see the history of Christianity in Hispania in the next episode.

The natives adopted Roman customs as well. They adopted Roman clothes and names, again starting from the elites to then expand to lower social classes; they abandoned the practice of human sacrifice; people started going to bathhouses to clean themselves and socialize; and Spanish people started attending the famous Roman spectacles. Spectacles were financed by the rich landowner class to please the masses, similar to modern sports like soccer or basketball. Greek and Latin plays spread Greco-Roman culture, but violent “games” like gladiator battles or elephants vs rhinos had a more important role spreading Romanization. I mean, just look at Mortal Kombat, that’s the real Roman legacy!

The process of Romanization also meant the adoption of Roman material culture, tastes and technology. The more economically integrated Hispania became to the Roman Empire, the more Spanish people adopted Roman currency, units of measure, taste for wine and olive oil, advanced farming technologies or Greek-styled techniques to build sculptures. The process of accepting Roman laws and judiciary system wasn’t easy, it took time and it wasn’t implemented immediately in all of Hispania. To illustrate this with an example, during the Late Republican period provincial governors started organizing assemblies in multiple locations during the winter to deliver justice within and between tribes. That created a stronger relationship of dependency towards Rome.

About the Romanization in terms of urbanism, the Romans founded the cities of Córdoba, Tarragona, Valencia, Palma de Mallorca, Pamplona, Seville, Mérida, Zaragoza, Barcelona… Rome, especially under Caesar and Augustus, founded many cities above native settlements following the Roman urbanist standards. It’s notorious though that some exclusively native towns eventually imitated Roman urbanism to look more Roman and improve their prestige.

Those were the aspects that involved the process of Romanization. But which were the key elements for this process? The first key element is the constant presence of Roman and Latin soldiers. There were between 20 and 25k soldiers permanently stationed in Hispania until the late 1st century, and if there was a campaign led by the consul you can double or triple these numbers. Many military camps later became permanent urban settlements, like it happened with León, Tarragona or the Roman neighborhood of Emporion. The importance of the soldiers in the Romanization process was not so much during their service, but after soldiers ended their military duties. Most received or were able to buy a land and farm it, and the majority married native women. The army’s role to Romanize Spain was twofold, Roman and Italic soldiers settled in Spain and Iberian and Celtic soldiers learned Latin and Roman costumes when they joined the army. Natives weren’t accepted as core soldiers for Rome overnight, during most of the Republican period natives served as temporary auxiliaries and fought using their weapons and tactics. But later they progressively integrated into the Roman army, as Italic soldiers started to serve in the legions and someone had to fill the vacuum left by the permanent Italic auxiliaries. Even before the Principate, there was already a legion entirely made up by Iberians. When native Iberians, Celts or Celtiberians returned to their towns, they returned knowing Latin and Roman costumes and they, in turn, Romanized their communities.

Hispania was to the Romans what America was to the Spaniards, a land of opportunities perfect to colonize. The fertile lands of the Guadalquivir and Ebro Valleys, the mines of Andalusia, Cartagena or the north, or the commercial opportunities attracted peasants, merchants, slavers and prostitutes alike. Why Romans and Italics migrated from their homeland? Since the 2nd century BC middle classes and free peasants became poorer due to the rise of patricians who bought lands and worked them with slaves. It was the increasing social inequality and poverty in Italy that encouraged Latin colonization in Hispania. Colonization was opposed by the Senate, but the army founded some colonies with both Roman citizens and Italic colonists, and later Caesar and Augustus promoted colonization with civil population too.

The army not only had the task to expand the empire and suffocate revolts, they also did public works like the building of roads or bridges that were so important to integrate the empire. Roman roads were key for Romanization and to maintain the empire. Without them, armies would have had difficulties to move, trade would have been more restricted to the coastline, and Roman culture wouldn’t have expanded as much as it did through the inner regions of the empire. The Julio-Claudian dynasty finished the construction of the most important roads of Hispania, the Via Augusta that connected the coastline from the Pyrenees to Cádiz, and the Via de la Plata that connected Mérida in modern Extremadura with the mines of the north.

We have seen the key elements from the Roman side, but there must be internal elements that explained the acculturation of the natives, because not all conquerors leave a lasting legacy. This is an issue I have already talked about in previous episodes, but local elites faced a dilemma with the arrival of the Romans: they could either collaborate or oppose them. The elites needed to evaluate what was better for their interests. The smart native leaders understood that it was better to be friends with Rome instead of enemies. The smart ones survived and preserved or even improved their position of power within their community, the fools who opposed Rome perished. Soon the elites learned Latin and Roman customs and adopted an external Roman look. Eventually that gave them privileges, as they were rewarded with Latin or even Roman citizenship.

Okay, I’ve covered the aspects and causes of Romanization, now I want to take the perspective of the inhabitants of the Iberian Peninsula to imagine how they reacted to the arrival of the Romans. Let’s start with the Greek colonists, who were the first inhabitants of the Iberian Peninsula to ask for Roman protection. Imagine you are a merchant who is an influential political leader in Emporion, the Greek commercial city located in modern Catalonia. News arrive that Hannibal desires to conquer the entire Iberian Peninsula. You know that if Carthage succeeds, your Greek countrymen will be driven out by Carthaginian merchants. At the same time, you know that Rome is an emerging power. From your perspective, Rome is the lesser evil, as Romans are closer to the Greek world. In addition to that the native Iberians control the plain while the Greek colony is pressed to the sea, so perhaps if Emporion shows unequivocal loyalty to Rome you and all your colleagues may be able to expand and stop feeling threatened by the natives you trade with. So you talk to your community and all of you decide to offer Emporion as the landing base for the Romans, and the Republic accepts the proposal.

emporion roman and greek city

After the Second Punic War Emporion flourished as a powerful city with expanded borders. Rome rewarded your city with the plains of the natives, tax exemptions and a monopoly for the production of bricks in Hispania. In your lifetime, Emporion grows economically and it’s clear that the decision to show a pro-Roman position was the right one. Yet, your grandson saw Emporion losing importance. The Romans established a military camp that soon became permanent. From this outpost the Roman town emerged, and waves of Roman and Italic immigrants arrived. They soon outnumbered the Greeks and the city lost its Greek identity, while at the same time Tarragona became the most economically powerful city of Hispania Citerior. A similar process happened in Cádiz, the most important Phoenician and Turdetani city of Hispania. The city had long been a friend of Carthage, but when they saw clearly who was going to win, they switched sides and made a treaty of friendship with Rome. In less than a century the city lost its identity and was Romanized, which isn’t surprising as Cádiz and the region of the Turdetani was the most urbanized of the Iberian Peninsula.

If we take the perspective of the Iberians, they only wanted to be left alone, to not be enslaved and to not have their lands devastated. But they soon realized that the Romans weren’t altruistic liberators, they were just other conquerors. The Celts and Celtiberians only had an economic interest in the war, the ones who served wanted to earn some money while maintaining their independence. They were left alone, for the moment.

I say that because during the first phase of Roman conquest, that’s between the Second Punic War and the Second Celtiberian War, the Republic had strong control over the Mediterranean coastline, but many inner regions were not controlled at all. The area above the Guadiana river and the region of the Celtiberians was out of Roman control. Rome could exert limited actual power over the territory conquered. Romans relied on pacts with the native elites, they constantly had to deal with rebellions and raids, and they could only recruit native auxiliaries on an irregular basis. A very illustrative example of the limited power the Romans had is seen in something as important as taxation. We can’t imagine a modern state that doesn’t directly tax its inhabitants, but that’s what happened during Republican Rome. The Republic leased the right of taxing to equites, for a previously set sum of money. In doing so, the Roman state avoided any risk of non-payment while the equites had all the incentives to do whatever was needed to cover their expenses and make money. Key cities like Emporion, Sagunto, Cádiz or the few Latin colonies founded during this period were exempted to pay taxes for their loyalty or status. Therefore, the tax burden fell on the native and less-urbanized communities, no doubt why Iberians started general uprisings against Roman rule. Roman and Italic colonizers started the Romanization in the areas that were more economically important, the Guadalquivir and Ebro Valleys, as well as the mineral-rich Cartagena, but again, the extend of the Romanization was quite limited.

In the second phase of Roman conquest, between the Numantine War and the Sertorian War, the Roman Republic had the Tagus River, in Central Spain, as the frontier of their Spanish possessions. With the defeat of the Sertorian supporters, Rome forced many native communities to use Roman currency and forced their relocation to plains to control more effectively the territory and prevent revolts. Those policies were adopted to pacify the conquered lands, but that in fact accelerated the process of Romanization. At this phase some tribes like the ones of modern Catalonia, Valencia, Aragon, and even some Vascones had their tribal unity substituted by local ties in urban areas. The Celtiberians still resisted Roman practices and their basic social institution, the gens, persisted. Latin was adopted to speak with the Roman ruling class and to speak with distant tribes, but to speak with others of their community they still spoke their language, and their laws were still the tribal ones.

The third phase and the pivotal point in the Romanization of Hispania was marked by the policies of Caesar, Augustus and his successors. Caesar granted, for the first time, the rank of municipium to entire cities, something that granted Latin citizenship. Caesar started the most ambitious policy of colonization yet, as Caesar saw in Hispania the perfect land to solve the social chaos and economic misery of the Italic peasants. Rome had been present in Spain for more than a century, there were fertile lands in the Mediterranean side of the Peninsula, it was relatively near Italy and during the civil war Hispania Ulterior was loyal to Pompey, so it was necessary to make the province loyal to him. All the conditions were aligned to take a step further to integrate Hispania.

roman and latin colonies

Caesar’s colonization policy was very successful, and his successor Augustus kept it and expanded it. But Augustus not only continued the policy of colonization and extension of Latin citizenship. If Caesar could conquer Gaul, he needed to complete the conquest of Hispania once and for all, submitting the sparsely populated northern regions of Asturias and Cantabria that raided from time to time their neighbors who were under Roman protection. The greatness of Augustus in Hispania didn’t only come from that conquest, he also started ambitious public works to transform Spain into a new Italy.

He then took the task of reorganizing the provinces. Augustus expanded Hispania Citerior and changed its name to Hispania Tarraconensis, and he also divided the province of Hispania Ulterior in two, the imperial province of Lusitania and the senatorial province of Baetica in Andalusia. Senatorial provinces were provinces that were controlled by the Senate instead of the Emperor, with little chances of rebellion and no legions stationed. You can imagine that Baetica was very Romanized at this point, as the newborn Roman Empire considered Baetica a core territory. The province was the richest region of Hispania, with its mineral resources and fertile lands for agriculture. But that’s not the only reason Baetica was the most Romanized region along the coasts of Hispania Citerior, I mean, remember, who inhabited those lands? The Iberians. And the Iberians, due to their location, had already interacted with other advanced civilizations, namely Greeks and Phoenicians. Their social structures and institutions were similar to those of Italy, only less advanced. That’s why the process of Romanization was easier in southern and eastern Spain.

On the other hand, Central Spain experienced a slower process of Romanization. How and to what extend were the peoples of Central Spain integrated into the Roman Empire? Roads, villas and urbanism were important elements to Romanize Central Spain. Villas were luxurious country houses built by landowners to control their states and show their wealth, and in heavily rural environments like Central Spain villas were the expression of Roman culture. Urbanism in Central Spain was a middle ground between the large cities of southern and eastern Spain and the sparsely populated northern regions. That’s why Central Spain took more time to Romanize, but it ended up Romanized anyway. A good indicator of how Romanized it was is that by the 1st century AD Central Spain could be demilitarized.

The other area is Northern Spain, that received little Roman cultural influence during the entire lifetime of the Roman Empire. Some Roman legions were stationed to protect the mines, but in most of those areas Romans only showed up every now and then. Because of that ancient tribal structures, native languages and local laws survived well into the Principate.

Before we get into the political history of Hispania during the Principate, I want to discuss the economy of Hispania of this era. The most outstanding sectors of the Hispano-Roman economy of the Principate were agriculture, mining and salting. Hispania was not anymore the breadbasket of Rome like Egypt, nor the wealthiest region of the empire. Yet Hispania presented opportunities to farm new lands and the greatest source of mineral wealth of the Roman Empire, with the far Britannia as the only province comparable in mineral resources. Hispania exported cereals, but also olive oil and wines that had an excellent reputation over the empire. Olive oil production was so important that in Rome they built the artificial Monte Testaccio with a height of 35 meters. They built it using a huge number of broken amphoras that mostly came from Baetica, modern-day Andalusia. In fact, the Romans were the ones who introduced olive trees and grapes on a large scale. While Baetica greatly increased olive oil and wine production, that meant that there was less land used to produce grain. Central Spain probably had the role of growing cereals for the rest of Hispania, as the dry Meseta it’s ideal for that. Grain must have been transported through roads or rivers to later be shipped by sea. Among the changes the Romans introduced in the Spanish agriculture, they made clearer distinctions between common and private lands and introduced new farming tools and more efficient agricultural techniques. All that allowed to have, to some extent, a market-oriented rural economy.

The second industry I mentioned was mining, and you may remember that Rome found very attractive the mineral wealth of the Iberian Peninsula. The mines of Cartagena, Andalusia and later northern Spain became very important for the empire. The mines of Baetica lost importance in the late 2nd century, as the mines of Britannia were easier to exploit and were very rich, but the mines of the north maintained their importance even in the Late Roman Empire. Mines were initially owned and exploited by the state, but later Rome leased mines to Roman businessmen. The exploitation of mines required skilled workers and the foundation of colonies, so we can say that mining was a pillar for the Romanization of Spain too.

The third outstanding industry I mentioned was salting, that involved the extraction of salt and fishing to later commercialize salted fish. Cartagena, Cádiz and other cities of southern Spain and Lusitania became famous for this activity. In addition to salted fish, Spanish salting factories produced a very popular sauce in Italy and Greece, garum. This may sound very disgusting, but this sauce was made from fermented fish intestines. There are only two reasons someone would consume salted fermented fish intestines, to use it as an aphrodisiac or as a medicine, and garum was used for both. To end this economic talk, I wanted to add that hunting, horse breeding and the manufacture of textiles and pottery were important industries as well.

Now let’s make an overview to the political evolution of the Roman Empire from the Julio-Claudian dynasty to the Severan dynasty. I’ve already talked about how Caesar and Augustus of the Julio-Claudian dynasty boosted the economic development, Roman colonization and integration of Hispania into the empire. Nero was the last of the Julio-Claudian dynasty and the Flavian dynasty took the Roman throne in 69 AD. Emperor Vespasian issued the Edict of Latinization that gave not the Roman but the Latin citizenship to all the free Hispano-Romans, including the inhabitants of central and northern Spain that weren’t very Romanized. That was the definitive step for the integration of Hispania into the Roman Empire. This was the largest extend of rights given by Rome since the Republic gave Roman citizenship to all the freemen of Italy. But why did Vespasian take a measure of this magnitude? There are several reasons that explain the Edict of Latinization. One is purely political, Hispania helped Vespasian to reach his position, but the other was that Hispania was enough Romanized to at least give Latin citizenship, which was inferior to the Roman in theory but not so much in practice at this point. To mention another factor, as Italy grew wealthier, less Romans wanted to serve in the legions, and giving Latin citizenship to Hispano-Romans facilitated and encouraged recruitment.

Vespasian wanted to accomplish several objectives in Hispania: to reduce the size of the army in Hispania and relocate the legions to more problematic regions; to use more extensively Spanish manpower; to promote the mines of the north and the region of Lusitania; and to promote municipalities. By giving Hispano-Romans a more active role in the administration of the Roman Empire, Vespasian hoped he could purge the Senate and legions of disloyal Romans. It was during his reign that the administration of Hispania became civilian instead of military.

Because of the Edict of Latinization of Vespasian, a powerful faction of senators from Hispania emerged and that very same faction would soon promote, in the early 2nd century, two Hispano-Roman emperors, Trajan and Hadrian. Trajan became the first emperor born outside Italy and is considered to have equaled or even surpassed Augustus. He embraced the stoic ideals of the also Hispano-Roman Seneca to govern: austerity, kindness, self-demand, meritocracy, respect and tolerance without renouncing to authority and determination, and impassivity against adversity. That’s why he was called Optimus Princeps, which means best first citizen. He implemented social welfare policies, promoted an extensive public works program over all the empire and expanded the empire to its maximum extend with the conquest of Dacia and his campaigns in Mesopotamia.


Trajan favored Hispano-Romans in both administrative positions and the army, and that was criticized by some sectors of the Roman oligarchy. During Trajan’s rule recruitment in the wealthy Hispania Baetica diminished as it happened in Italy, while many auxiliaries came from the poorer north. To end the talk about him, it’s remarkable how Hispania benefited from his public works program. Trajan ordered the expansion of cities, the building of bridges and amphitheaters and the reparation and extension of Roman roads, with special attention to the neglected region of Lusitania.

His successor, Hadrian, adopted a policy of consolidating the gains and establishing defensible borders, as it’s exemplified by Hadrian’s Wall in Britannia, but also by the withdrawal of Roman troops from the recently conquered Mesopotamia. Hadrian continued the policies of social welfare and public works of his predecessor. The Hispano-Roman Emperor travelled throughout the Roman Empire to know the problems the empire had and to solve them. For instance, he gathered in Tarragona an assembly with representatives from all Hispania and asked them to contribute with an important number of soldiers to solve the problems in Britannia and Mauritania. His proposal was met with fierce resistance at first, but Hadrian and the representatives reached an agreement at last. Hadrian relied heavily at first on Hispano-Romans for key administrative positions and to fill the ranks of the army, but that changed as years went by. Overall the governments of Trajan and Hadrian are remembered for their prosperity, justice and relative peace.

Hadrian was succeeded by Antoninus Pius, who had a reign marked by peace. Antoninus proved to be a very good administrator, as he left the office with a huge surplus in the treasury. He also expanded access to drinking water and built Roman roads in Gaul, modern-day France. Nonetheless, the empire started showing signals of stagnation under him, and Antoninus Pius barely did anything in Hispania, although that may be reasonable since previous emperors had dedicated enough attention to the region. The reigns of Marcus Aurelius and Commodus represented the end of the Pax Romana and the start of the slow decadence of the Roman Empire. The Antonine Plague desolated the empire, killing as much as 20 to 30% of the population, and to make things worse the Roman Empire suffered raids from Germanic tribes in the northern frontier and Berber tribes from North Africa in Hispania. The economy of Hispania resented from plagues and raids, but also from heavy taxes and levies. The population of Hispania is estimated to have been around 6 or 7 million people before the Antonine Plague, equal to that of the Italian Peninsula. But after that, population declined to around 5 million, and the population of Hispania remained more or less constant up to the Renaissance. Yep, more than ten centuries after the plague.

With Commodus the Antonine dynasty ended, and the Severan dynasty eventually seized power at the end of the 2nd century. The Severans sowed the seeds for an economic crisis, they exponentially increased the salaries of the soldiers, but since the state couldn’t pay for that they decided to devaluate the Roman currency. Eventually that generated high inflation, distrust in the Roman monetary system and in general an economic mess. Hispania specifically suffered more since landowners started spending more capital in North Africa. Regarding the military, the recruitment of Hispano-Romans massively decreased from the rule of Septimius Severus onwards, as it had happened with Italians.

The infamous Caracalla then conceded Roman citizenship to all the free peoples of the Roman Empire, not as an act of altruism but to tax more and to have more available manpower for the army. That didn’t affect much Hispania, as many already had Roman citizenship and every free Hispano-Roman had the very similar Latin citizenship. With that law Roman citizenship stopped being something to be proud of, because everyone had it, and for the ones who hadn’t they saw how they had to pay more taxes now, so they weren’t happy either. Severus Alexander became the last of the Severan dynasty, his reign was relatively peaceful, although with the rising Sassanid Empire and Germanic tribes threatening Roman power. What was worse and fatal for Severus Alexander was the breakdown of military discipline and continuous conspirations within the army. He was eventually assassinated by mutineers in Germania in 235, ending the Principate and beginning the Crisis of the Third Century that almost collapsed the Roman Empire.

THE VERDICT: I’m sure many of you had already heard about Romanization before, but it’s not an exceptional cultural phenomenon at all. There are actually many historical and current phenomenon of cultural assimilation that end with -zation. Hispanicization, Anglicization, Russification, even fucking Uzbekization and this is not a meme. But this is what happens with cultures, they can be transmitted in a more peaceful way, sometimes cultures can be imposed, but what’s common is that states try to expand their borders, their wealth and of course their culture. The desire to grow, expand and possess are the essence of human nature, and that’s how empires rise. And with that, The Verdict ends.
