Caligula (August 12 AD - 22 January 41 AD), also known as Gaius, was 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 from his father's soldiers while accompanying him during his campaigns in Germania.
