The 3rd roman emperor tried to make his horse a consul and a priest

Gaius Julius Caesar Augustus Germanicus ( 31 August 12 – 24 January 41), more commonly known by his cognomen Caligula (pronounced /kəˈlɪɡjʊlə/), was the third Roman Emperor, reigning from 16 March 37 until his assassination on 24 January 41. Caligula was the third emperor of the Roman Empire, and a member of the house of rulers conventionally known as the Julio-Claudian dynasty.

Perhaps most famously, they say that Caligula tried to make his horse, Incitatus, a consul and a priest.^[104] The validity of these accounts is debatable. In Roman political culture, insanity and sexual perversity were often presented hand-in-hand with poor government
