A protectorate, in international law, is an autonomous territory that is protected diplomatically or militarily, or both, against third parties by a stronger state or entity. In exchange for this, the protectorate usually pays something, and accepts specified obligations, which may vary greatly, depending on the real nature of their relationship. However, it often retains a sufficient measure of sovereignty and remains a state under international law.
