"Caligula" (Latin: Gaius Julius Caesar Augustus Germanicus;) was the popular nickname of Gaius (31 August 12 AD – 22 January 41 AD), Roman Emperor from 37 AD to 41 AD. Caligula was a member of the house of rulers conventionally known as the Julio-Claudian dynasty. Caligula's father Germanicus, the nephew and adopted son of Emperor Tiberius, was a very successful general and one of Rome's most beloved public figures. The young Gaius earned the nickname Caligula (meaning "little soldier's boot", the diminutive form of caliga, hob-nailed military boot) from his father's soldiers while accompanying him during his campaigns in Germania.
