Extreme tyranny or despotic rule, named after the Roman Emperor Caligula who was known for his brutal and erratic behavior.
From Caligula, the 1st-century Roman emperor whose reign was marked by madness and cruelty. The suffix '-ism' converts his name into a concept describing tyrannical governance. His actual name was Gaius, and 'Caligula' was a childhood nickname meaning 'little boot.'
Historians still debate whether Caligula was actually as insane as ancient writers claimed, or if political enemies exaggerated his crimes—but his name became so synonymous with dangerous power that it created its own vocabulary word!
