Caligula's Grandfather: Augustus Augustus succeeded Julius Caesar. His reign was long and prosperous despite vicious political manoeuvering regarding his successor, and he is usually identified with the political and cultural "golden age" of the Roman Empire.
	Caligula's Father: Germanicus Germanicus, Caligula's father, was the nephew of Augustus and was not only the most competent of potential heirs but also the popular choice. His mysterious death while on foreign duty was often attributed to Tiberius.
	Caligula's Uncle: Tiberius Tiberius was the son of Augustus's powerful wife, Livia. After scheming to succeed Augustus, his reign was marked by increasingly evil and grotesque behaviour. He took a fancy to young Caligula and initiated him into a life of perversity.
	Caligula Caligula was identified with his heroic father Germanicus and seemed to provide a contrast to his hated uncle, Tiberius. That was why he was the universal choice to succeed Tiberius as Emperor. Rome (especially the aristocracy) soon came to regret this collective delusion.
	Caligula's Sister: Drusilla Caligula was especially "fond" of his sister Drusilla, and his grief after her death was used by Camus as the symbolic key to the dramatic action of Caligula. But the historical Caligula's relationship to all three sisters (Drusilla, Agrippina & Livia) was incestuous and sadistic.
	Caligula brutalized his two brothers, Drusus and Nero (not the later Emperor who fiddled while Rome burned). They were eventually killed.
