A federated state (which may be referred to as a state, a province, a canton, a Land, etc.) is a territorial and constitutional community forming part of a federal union (federation). Such states differ from fully sovereign states, in that they have transferred a portion of their sovereign powers to a federal government. Importantly, when states choose to federate, they lose their standing as persons of international law. Instead, the federal union as a single entity becomes the sovereign state for purposes of international law. A federated state holds administrative jurisdiction over a defined geographic territory and is a form of regional government.
