North Solomon Islands
Coordinates: 6°14′40″S 155°23′02″E / 6.24444°S 155.38389°E The Northern Solomons were the more northerly group of islands in the Solomon Islands archipelago over which Germany declared a protectorate in 1885. Initially the German Solomon Islands Protectorate included Choiseul, Santa Isabel, the Shortlands and Ontong Java Islands, but in 1900 these islands were transferred to the British Solomon Islands Protectorate. The largest of the Solomon Islands, Bougainville, continued under German administration until World War I when it fell to Australia, and after the war, it formally passed to Australian jurisdiction under a League of Nations mandate.
Today, the original North Solomon Islands are split between the Autonomous Region of Bougainville in Papua New Guinea and the successor state of the British Solomon Islands which was officially renamed from the British Solomon Islands Protectorate to Solomon Islands in 1975 prior to becoming an independent, sovereign state in 1976.
