+A **confederation** is a union of [sovereign states](/wiki/Sovereign_State) bound by a treaty, often for common defense or economic goals. Unlike a [federation](/wiki/Federation), member states retain their full independence, ceding limited powers to the central authority, which typically acts on consensus.
