The Sheikhdom of Kuwait was a sheikhdom during the pre-oil era. The sheikhdom became a British protectorate between 1899 and 1961 following the Anglo-Kuwaiti agreement of 1899. This agreement was made between Sheikh Mubarak Al-Sabah and the British Government in India, primarily as a defensive measure against threats from the Ottoman Empire. After 1961, the sheikdom became the state of Kuwait.

A protectorate, in the context of international relations, is a state that is under protection by another state for defence against aggression and other violations of law. It is a dependent territory that enjoys autonomy over most of its internal affairs, while still recognizing the suzerainty of a more powerful sovereign state without being a possession. In exchange, the protectorate usually accepts specified obligations depending on the terms of their arrangement. Usually protectorates are established de jure by a treaty. Under certain conditions—as with Egypt under British rule (1882–1914)—a state can also be labelled as a de facto protectorate or a veiled protectorate.
