'In fact, except for Italy, which was not considered a province in these centuries, all the territories of the empire were organised into provinces and subject to taxation'. Explain.
1. The Roman Empire stretched from Scotland to the borders of Armenia, and from the Sahara to the Euphrates and sometimes beyond. Given that there was no government in the modern sense to help them to run things, you may well ask, how was it possible for the emperor to cope with the control and administration of such a vast and diverse set of territories, with a population of some 60 million in the mid-second century. The answer lies in the urbanisation of the empire.
2. The great urban centres that lined the shores of the Mediterranean (Carthage, Alexandria, Antioch were the biggest among them) were the true bedrock of the imperial system. It was through the cities that ‘government’ was able to tax the provincial countrysides which generated much of the wealth of the empire. What this means is that the local upper classes actively collaborated with the Roman state in administering their own territories and raising taxes from them. In fact, one of the most interesting aspects of Roman political history is the dramatic shift in power between Italy and the provinces.
3. Throughout the second and third centuries, it was the provincial upper classes who supplied most of the cadre that governed the provinces and commanded the armies. They came to form a new elite of administrators and military commanders who became much more powerful than the senatorial class because they had the backing of the emperors.
As this new group emerged, the emperor Gallienus (253-68) consolidated their rise to power by excluding senators from military command. We are told that Gallienus forbade senators from serving in the army or having access to it, in order to prevent control of the empire from falling into their hands.
4. To sum up, in the late first, second and early third centuries the army and administration were increasingly drawn from the provinces, as citizenship spread to these regions and was no longer confined to Italy. But individuals of Italian origin continued to dominate the senate at least till the third century, when senators of provincial origin became a majority.
These trends reflected the general decline of Italy within the empire, both political and economic, and the rise of new elites in the wealthier and more urbanised parts of the Mediterranean, such as the south of Spain, Africa and the east.
A city in the Roman sense was an urban centre with its own magistrates, city council and a ‘territory’ containing villages which were under its jurisdiction. Thus one city could not be in the territory of another city, but villages almost always were.
Villages could be upgraded to the status of cities, and vice versa, usually as a mark of imperial favour (or the opposite). One crucial advantage of living in a city was simply that it might be better provided for during food shortages and even famines than the countryside.
