Santa Isabel Island
In April 1885 a German Protectorate was declared over the North Solomon Islands, including Santa Isabel Island. In 1900, under the terms of Treaty of Berlin (14 November 1899), Germany transferred the North Solomon Islands (except for Bougainville and its surrounding islands) to the British Solomon Islands Protectorate in exchange for the British giving up all claims to Samoa. Missionaries settled on Santa Isabel Island under both protectorates, converting most of the population to Christianity. In the early 20th century several British and Australian firms began large-scale coconut planting.
