 Politics also played a factor; emperors found they could rarely trust a large army to a potential rival, though Augustus had enough loyal family members to wage his wars.Also, Augustus, in his 40-year reign, had annexed many territories still at the beginning of the process of Romanization.Tiberius, who succeeded Augustus in AD 14, decided that Germania was a far less developed land, possessing few villages and only a small food surplus, and therefore was not currently important to Rome.
