    Rulers of six Trucial sheikhdoms signed the Exclusive Agreement between 6 and 8 March 1892, establishing exclusive British relations.

Background and detail

Background. The sheikhdoms had previously allied with Britain through a series of treaties beginning with the General Maritime Treaty of 1820 and including the Perpetual Maritime Truce of 1853. The 1892 treaty was established primarily in reaction to the ambitions of France and Russia, creating closer bonds between Britain and the Trucial Sheikhdoms.

Terms of the Agreement. The signatories agreed not to enter into any agreement or correspondence with any power other than the British Government. They also agreed not to consent to the residence of agents of other governments or to cede, sell, or mortgage any part of their territory without British assent.

Protectorate Status. The agreement cemented the status of the Trucial States as a British protectorate, although it did not formally confer this status. It created an unclear 'protected state' status requiring Britain to defend the sheikhdoms from external aggression in exchange for exclusive rights.
