Caligula

This term refers specifically to the historical figure Gaius Caesar, though it is often used as a shorthand for the archetype of a decadent, erratic, and tyrannical ruler. In historical and political discourse, invoking the name serves as a cautionary reference to the dangers of absolute power coupled with mental instability.

As a proper noun referring to a unique individual, the word does not follow standard countability rules and is used exclusively in the singular. It is always capitalized to denote the specific Roman emperor.
