Gaius Julius Caesar (13 July 100 BC – 15 March 44 BC) was a Roman general and statesman. He played a critical role in the gradual transformation of the Roman Republic into the Roman Empire.

Gaius Julius Caesar Augustus (23 September 63 BC – 19 August AD 14) is considered the first emperor of the Roman Empire, which he ruled alone from 27 BC until his death in AD 14. Born Gaius Octavius Thurinus, he was adopted posthumously by his great-uncle Gaius Julius Caesar in 44 BC via his last will and testament, and between then and 27 BC was officially named Gaius Julius Caesar.

Gaius Julius Caesar Augustus Germanicus (31 August AD 12 – 24 January AD 41), commonly known as Caligula and sometimes Gaius, was Roman Emperor from 37 to 41.

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 (the diminutive form of caliga meaning "little soldier's boot") from his father's soldiers while accompanying him during his campaigns in Germania.
