How did panem come into use?

Panem, derived from the Latin phrase "Panem et Circenses" meaning "bread and circuses," is a fictional setting from Suzanne Collins' "The Hunger Games" series. It represents a dystopian society that emerged after a series of catastrophic events, including natural disasters and societal collapse, leading to the rise of a totalitarian regime. The term reflects the government's strategy of appeasing the populace with basic needs and entertainment to maintain control. The concept has since been used in discussions about political power and social control in real-world contexts.
