Solomon Islands is a sovereign state in the Melanesia subregion of Oceania in the western Pacific Ocean. This page is about the history of the nation state rather than the broader geographical area of the Solomon Islands archipelago, which covers both Solomon Islands and Bougainville Island, a province of Papua New Guinea. For the history of the archipelago not covered here refer to the former administration of the British Solomon Islands Protectorate, the North Solomon Islands and the History of Bougainville.
