Emperor of Rome, succeded Tiberius.
When he was little, he was beloved by the Roman army. They nicknamed him "Little Boots" and made him their mascot.
Indeed, it appeared as though Caligula had it all. But Roman politics soon took it all from him.
Tiberius had most of his family killed and took little Caligula to live with him on the Isle of Capri.
It's hard to imagine how the young man felt, having to serve the same man who shattered his life.
But it seems likely that it left him with a lingering hatred of Rome, it's traditions and politicians.
So, when Caligula became Emperor, people initially rejoiced. But he soon ushered in an anarchic reign, designed to ridicule the establishment.
He made the army gather seashells, he threatened to make his horse - Incitatus - a senator, he dressed as Roman Gods.
The Roman elite would only take so much of this mockery. Eventually, they cornered Caligula in a hall way and hacked him to death.
Caligula is often portrayed as being insane. But it seems more likely that he was merely filled with a loathing of Rome because of his traumatic childhood.
Caligula's attacks on the establishment indicate that he was some form of primoridal anarchist. His actions were calculated, rather than being the random antics of a maniac.
