Caligula
Caligula, who was chosen as emperor by his great-uncle Tiberius, may have given the order to suffocate his patron. His election was well received, but after seven months, "Little Boots" appeared to turn into a monster due to a sickness. He is referred to as a wicked emperor primarily due to claims that he killed on the spur of the moment and supported himself through authorized theft.
In spite of a prophecy, he constructed a two-mile pontoon bridge only so he could ride his horse across the Bay of Baiae. Incitatus the horse resided in a marble stable and may have been appointed a consul by Caligula. He began to promote himself as a god about the year 40 AD, and his castle was referred to as a brothel, complete with the purported whores of his own sisters.
The journey to Egypt to live as a sun deity was the final straw after starvation and bankruptcy. This led to his assassination in January of the year 41 AD. He is one of the worst Roman Emperors.
Time: 37 - 41 AD
