The reign of Hadrian marks the beginning of a new epoch in Roman administration and in the history of Roman Law. Hadrian's visit to Britain is immortalised by the Wall which he built from Tyne to Solway. Its construction is characteristic of the Emperor's willingness to renounce further conquests and even to abandon land which had been Roman. The Wall marked the limit of the districts which he was prepared to retain and administer. It followed, not the shortest and easiest route, but a line beyond the fortified area whence a look-out could be kept over the barbarians outside, and its object was the completion and definition of the fortified frontier region whereby it became easier to civilise and to pacify the country which lay to the south. Hadrian's aim was to bring order and peace to the land bounded by the new frontiers of the Roman world. Thus Hadrian may be sharply contrasted with his predecessor Trajan, the soldier on the throne, who owed his elevation to his successful wars in the Rhine region, and who as Emperor extended the frontiers of the Empire on the lower Danube and in the East. On Hadrian's accession the Empire was more powerful than ever before or afterwards, but its financial and military resources were strained to the utmost, and indeed frequently had been overstrained. The small peasant owners and small towns, sources of Roman culture and prosperity, had begun to suffer and disappear.
