On this day in 47AD, the Roman Emperor Caligula, a despotic sadist of unmeasured proportions, was assassinated by his own guards.
He reigned for three years and 10 months and in that time, the fear and paranoia he engendered was fueled, in part, by a system of household spies he put in place. He used slaves and guards, and members of his own family to learn of plots against him.
He also listened to bodiless voices, who proclaimed him a god, too.
No one’s perfect, I guess.
