The ancient Mediterranean was a world of cities and in the eastern Mediterranean at least, it had been long before the Roman period. By the beginning of the Roman Republic (509 BC), the pattern of organization was broadly similar in Italy, Sicily, coastal North Africa, Egypt, the Levant, Mesopotamia, Anatolia and Greece: agricultural land was broken up into the territory of cities (so that each city consisted of both its urban core but also its agricultural hinterland). Those cities might then either be independent, as with the poleis of Greece and the various communities of pre-Roman Italy, or be the basic administrative units of larger empires, as in the Persian Empire (or later Roman Italy). And so, while most people still lived in the countryside, most of that countryside was in turn attached to an urban center which was the center of political, economic, religious and cultural life.

This was the world the Romans knew and the world they were most comfortable governing. Consequently, while the Romans were utterly uninterested in “civilizing” anyone, when they conquered areas which weren’t urbanized, they tended to found cities or encourage local urbanization in order to create the administrative structures through which the Romans could extract revenue most efficiently.

As mentioned above, the Romans generally wanted these cities to be mostly self-governing. While at conquest, the Romans found themselves managing a bewildering array of different styles of local urban government, over time a mix of Roman administrative preference and cultural diffusion tended to produce a fairly similar set of civic institutions. City governments, which also administered their rural countryside, were run by a town council which consisted of the wealthiest notables of the town – the curiales – in much the same way that the Roman upper-class had dominated the running of the city during the Republic. Roman authority generally protected the curiales and their wealth from the sorts of popular uprisings that tempered many Greek oligarchies in the classical period and in return the curiales managed the population and the collection of taxes for the Romans.

The curiales both managed the town affairs and were also expected to use their own wealth to fund public activity and works: maintain temples and baths, fund religious rituals and festivals, and so on. Through the first and second century, that process was mostly responsible for providing the cities of the Roman Empire with the impressive collection of often still-visible public works they boasted: baths, theaters, amphitheaters, aqueducts, temples, courthouses, public spaces and so on. While some of these structures were little more than the public posturing of the elites, many of them were open to the general public and will have represented, in as much as anything before the industrial revolution could, meaningful improvements in the lives of regular people.

While most of the wealth of any of these cities was derived from the rents and taxes extracted from their agricultural hinterlands, these cities also substantially lived off of trade and markets. Because the local city typically housed the local market, they were the obvious point for local products to enter the stream of provincial-wide or empire-wide trade or for distant imports to reach their final customers. We’ll come back to this next time when we discuss trade and the economy, but for now I want to note that this trade provided a fair bit of the economic vitality of these cities but also that it did in fact reach down beyond mere luxury goods into the basic staples that even the relatively poor might buy.

The decline and fall of these Roman cities is most extensively described in J.H.W.G. Liebeschuetz’ aptly titled, Decline and Fall of the Roman City (2001). Given his title, as you might imagine, Liebeschuetz is in the “decline and fall” camp, arguing that the classical city which defined the Roman world largely did not survive it. Regional patterns differ, with Liebescheutz identifying three “patterns”: I) Western and Central Anatolia, II) Syria, Palestine and Arabia, III) the west, including North Africa).

We’ll deal with the situation in the east in just a moment, so let’s focus here on the cities of the west, which were at the start generally smaller, less wealthy and generally far younger than those of the east (with some exceptions in Italy). Decline sets in fastest and is most severe in Britain, with the final collapse of the cities coming as early as the 360s, whereas in North Africa, the classical city doesn’t seem to tip into decline until after 400.

While each individual region and indeed each city will have been subject to its own unique conditions, a few basic causes seem to have been active everywhere to some degree. First, the crisis of the third century seems to have fundamentally disrupted empire-wide Roman trade, which then stabilized at a lower level for the fourth century, before declining precipitously in the fifth. That first decline seems to have been somewhat offset by the increased demands of imperial administration and in particular the centralized taxation in-kind and movement of goods which had to move through cities. Peter Brown describes the late Roman state as, “the crude but vigorous pump which had ensured the circulation of goods in an otherwise primitive economy” (The Rise of Western Christendom, 2nd ed., 13). We’ll return to this when we discuss the shape of the economy next time, but for now it works as a crude, but vigorous description of that facet of the late Roman economy.

At the same time, as Liebescheutz describes, the role of the curiales steadily atrophies in the fourth century. On the one hand, much of the authority and power of being on the council was steadily eroded as those functions were pulled upwards into the imperial bureaucracy. At the same time, members of the curial class who sought imperial office could get immunities from the progressively more severe taxation which otherwise often fell on the curiales and so the imperial elite often crowded out the curiales when it came to wealth and prestige in the community. As they lost both control and responsibility for their cities, the curiales‘ investment in public works and monumental architecture also ceased (though local elites do invest in church-building and monastic foundations), leading to the decay of the physical urban centers.

Finally, the warfare of the fifth century had its impact, though as Liebescheutz notes, it cannot be presented as a sole cause simply because many urban areas were already clearly in decline when conflict hit. In the case of Britain, the cities were gone by 420, decades before the arrival of any invaders. Nevertheless, political instability and violence in the fifth century seems to have delivered death-blows to ailing communities, especially in the Balkans and along the Rhine.

The end result was that in the West, urbanism declined severely between the fourth and sixth centuries. Rome, once a city of a million people, collapsed down to a population of just 80,000. Arles, which had been a thriving Roman city with an amphitheater, an aqueduct, a chariot-racing track, a theater and full city walls shrunk so severely that the remains of the city moved inside its amphitheater, repurposing it as a new set of city walls, with the town square in the middle and houses built in the stands. While many towns survived in their new, shrunken and impoverished form, urbanism in Europe outside of the Eastern Roman Empire would largely have to be reinvented during the High Middle Ages, (though with some key institutional survivals from the Roman era and often rising out of the diminished remains of Roman cities). Instead, the society of the early Middle Ages was overwhelmingly rural in both population and focus. If on politics we have a bit of a mix between decline and continuity, when it comes to the cities that made up the old political system, the “decline and fall” knight strikes a clear blow: the system of social organization that characterized the ancient world practically vanished and would have to be redeveloped centuries later. The institutions that had maintained it (like the curiales) largely vanished, replaced in some cases by local “notables” and in other cases by ruralization.
