7Caligula

Gaius Julius Caesar Augustus Germanicus, better known by his nickname Caligula, was the third Roman emperor, ruling from 37 until his assassination in 41.

Caligula, considered by many to be a mad and unpredictable tyrant, is also known for transferring the last legion under a senatorial proconsul to an imperial legate, completing the emperor’s monopoly of army command. It was rumoured that he planned to appoint his horse consul before he died.
