Gaius Julius Caesar Augustus Germanicus, known by the nickname “Caligula” (“little boots”) from his early youth, had arguably the most illustrious family tree in history: son of the war hero Germanicus, grandson of the war hero Marcus Agrippa, great-grandson of both Augustus and Marc Antony.  Yet in his turn as Princeps, he was considered an insane tyrant by his contemporaries – prone to cruelty, sadism, extravagance, and sexual perversity.  In early AD 41, Caligula was assassinated as a result of a conspiracy by officers of the Praetorian Guard, senators, and courtiers.
