A federal territory is an administrative division under the direct and usually exclusive jurisdiction of a federation's national government. A federal territory is a part of a federation, but not a part of any federated state. The states constitute the federation itself and share sovereignty with the federal government, while a territory does not have sovereign status and is constitutionally dependent on the federal government.
