Although Augustus' succession plans were all but ruined due to the deaths of more than several family members, including many of his own descendants, in the end, Tiberius remained faithful to his predecessor's wishes that the next emperor would hail from the Julian side of the Imperial family. Thus, Tiberius was succeeded by Gaius Julius Caesar Augustus Germanicus, the sole-remaining son of his nephew and adopted son Germanicus. The new emperor was a great grandson of Augustus through his mother Agrippina the Elder thus making him a Julian but he was also a Claudian through his father Germanicus being the son of Livia's younger son Drusus the Elder. More commonly remembered in history by his childhood nickname Caligula, he was the third Roman Emperor ruling from AD 37 to 41.
