Augustus adopted Tiberius as his heir after noting his success in military campaigns across Germany. Tiberius was reluctant to take rule, however, and gained a reputation as “the exile” after he sent himself on an eight-year, self-imposed exile to Rhodes. Eventually he did take control of the empire, but he gained a reputation for cruelty which led Rome to rejoice at his eventual death. In this excerpt from The Twelve Caesars, Roman biographer Suetonius digs deep into both the conquests and character of Tiberius.
