The reign of Tiberius

TIBERIUS, AN UNPOPULAR BUT ABLE RULER. The reign of Tiberius (b. 42 B.C., d. A.D. 37, emperor A.D. 14-37) is a particularly important one for the Principate, since it was the first occasion when the powers designed for Augustus alone were exercised by somebody else. [[1]] In contrast to the approachable and tactful Augustus, Tiberius emerges from the sources as an enigmatic and darkly complex figure, intelligent and cunning, but given to bouts of severe depression and dark moods that had a great impact on his political career as well as his personal relationships. His reign abounds in contradictions. Despite his keen intelligence, he allowed himself to come under the influence of unscrupulous men who, as much as any actions of his own, ensured that Tiberius's posthumous reputation would be unfavorable; despite his vast military experience, he oversaw the conquest of no new region for the empire; and despite his administrative abilities he showed such reluctance in running the state as to retire entirely from Rome and live out his last years in isolation on the island of Capri. His reign represents, as it were, the adolescence of the Principate as an institution. Like any adolescence, it proved a difficult time.
