The word "confederation" traces back to Latin confoederatio, combining con- (together) and foederare (to ally, from foedus, meaning "league" or "treaty"). The root feder evolved into English via Old French, retaining its core idea of a binding agreement. The suffix -ation nominalizes the concept, forming "confederation" as a formal union with shared governance. Historically, it reflects political alliances like the Swiss Confederation (1291), emphasizing decentralized cooperation.
