Tiberius had contributed peace to the Empire by diplomacy between Rome and the Provinces rather than military solutions, as he was interested in saving his men that pursuing personal glory on the battlefield. Tiberius" military training had given him a concern for order and discipline, which he saw as the basis of good government.
In foreign policy, Tiberius primarily maintained the frontiers of the Roman Empire. Tiberius tried a new policy of containment by allowing some tribesmen to settle on the north bank of the river under their own ruler. They would act as a first line of defense against other tribes and thus contributed the safety to the people of Rome. Tiberius allowed Roman borders to monitor traffic during peaceful times and for trade. Roman Foreign policy took advantage of economic possibilities in maintaining good relations with other nations and thus, with trade, is able to contribute a variety of goods to Rome and it's Empire.
Tiberius made a financial contribution to Rome by lowering the unpopular one percent sales tax to half a percent. When faced with financial crisis in AD 33, he increased the circulation of money by lending the treasury one hundred million sesterces, interest free, for 3 years.
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. 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. .
Though Tiberius treated the Senate with respect and was prepared to increase their authority, his failure to make decisions, his tendency to simply leave matters to them and the ambiguity of his instructions created doubt and confusion in Rome.
