The Southern Federation comprises the states of Koror, Peleliu and Angaur. However, fewer and fewer Palauans have knowledge of the concept of federations, and the term is slowly dying out. Federations were established as a way of safeguarding states and hamlets who shared economic, social, and political interests, but with the advent a federal government, safeguards are less meaningful. However, in international relations, the king of Palau is synonymous with the Ibedul of Koror. This is because Koror is the industrial capital of the nation, elevating his position over the Reklai of Melekeok.
