Definition
A confederacy is a league or alliance of states or nations that come together for a specific purpose. Each member maintains a degree of independence but cooperates on matters of common concern like defense or trade. Unlike a federation, the central authority in a confederacy is usually weaker, and members retain significant autonomy. Think of it like a group of friends forming a study group – everyone studies their own way but meets to share notes. It is also used to describe historical or fictional political entities where member states retain sovereignty.
