Caligula

"Caligula" (/kəˈlɪɡjələ/; Latin: Gaius Julius Caesar Augustus Germanicus;) was the popular nickname of Gaius (31 August AD 12 – 22 January AD 41), Roman emperor (AD 37–41). 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.
