Tiberius became Augustus' stepson when the emperor married Livia in 38 B.C. Augustus forced Tiberius to divorce the wife he loved and to marry his daughter Julia. Tiberius hated his new wife and escaped her by going into voluntary exile at Rhodes in 6 B.C. After the deaths of the other possible successors, he was recalled in 2 A.D. and groomed to succeed Augustus, which he did on 19 August 14. The empire thrived under Tiberius; however, his reign was marred by a conspiracy to rule by his Praetorian Praefect Sejanus and by his descent into paranoia near the end of his reign. Tiberius moved to Capri in 26 and ruled from there until his natural death on 16 March 37.
