United Kingdom

Pre-Roman Celtic tribes had been ruled by kings and aristocracies; the Roman civitates remained in the hands of the rich because of the heavy expense of office. But since trade and industry now yielded increasing profits and the old aristocracies no longer derived wealth from war but only from large estates, it is likely that new men rose to power. Roman citizenship was now an avenue of social advancement, and it could be obtained by 25 years’ service in the auxiliary forces as well as (more rarely) by direct grants. Soldiers and traders from other parts of the empire significantly enhanced the cosmopolitan character of the population, as did the large number of legionaries, who were already citizens and many of whom must have settled locally. The population of Roman Britain at its peak amounted perhaps to about two million.

Economy

Even before the conquest, according to the Greek geographer Strabo, Britain exported gold, silver, iron, hides, slaves, and hounds in addition to grain. A Roman gold mine is known in Wales, but its yield was not outstanding. Iron was worked in many places but only for local needs; silver, obtained from lead, was of more significance. But the basis of the economy was agriculture, and the conquest greatly stimulated production because of the requirements of the army. According to Tacitus, grain to feed the troops was levied as a tax; correspondingly more had to be grown before a profit could be made. The pastoralists in Wales and the north probably had to supply leather, which the Roman army needed in quantity for tents, boots, uniforms, and shields. A military tannery is known at Catterick. A profit could, nonetheless, be won from the land because of the increasing demand from the towns. At the same time the development of a system of large estates (villas) relieved the ancient Celtic farming system of the necessity of shouldering the whole burden. Small peasant farmers tended to till the lighter, less-productive, more easily worked soils. Villa estates were established on heavier, richer soils, sometimes on land recently won by forest clearance, itself a result of the enormous new demand for building timber from the army and the new towns and for fuel for domestic heating and for public baths. The villa owners had access to the precepts of classical farming manuals and also to the improved equipment made available by Roman technology. Their growing prosperity is vouched for by excavation: there are few villas that did not increase in size and luxury as corridors and wings were added or mosaics and bath blocks provided. At least by the 3rd century some landowners were finding great profit in wool; Diocletian’s price edict (ad 301) shows that at least two British cloth products had won an empire-wide reputation. Archaeological evidence indicates that the Cotswold district was one of the centres of this industry.

Trade in imported luxury goods ranging from wine to tableware and bronze trinkets vastly increased as traders swarmed in behind the army to exploit new markets. The profits of developing industries went similarly at first to foreign capitalists. This is clearly seen in the exploitation of silver-lead ore and even in the pottery industry. The Mendip lead field was being worked under military control as early as the year 49, but under Nero (54–68) both there and in Flintshire, and not much later also in the Derbyshire lead field, freedmen—the representatives of Roman capital—were at work. By Vespasian’s reign (69–79) organized companies (societates) of prospectors are attested. Roman citizens, who must in the context be freedmen, are also found organizing the pottery industry in the late 1st century. Large profits were made by continental businessmen in the first two centuries not only from such sources but also by the import on a vast scale of high-class pottery from Gaul and the Rhineland and on a lesser scale of glass vessels, luxury metalware, and Spanish oil and wine. A large market existed among the military, and the Britons themselves provided a second. Eventually this adverse trade balance was rectified by the gradual capture of the market by British products. Much of the exceptional prosperity of 4th-century Britain must have been due to its success in retaining available profits at home.

A final important point is the role of the Roman army in the economic development of the frontier regions. The presence as consumers of large forces in northern Britain created a revolution in previous patterns of trade and civilized settlement. Cereal production was encouraged in regions where it had been rare, and large settlements grew up in which many of the inhabitants must have been retired soldiers with an interest in the land as well as in trade and industry.
