The first inhabitants of the Archipelago were the Lapita people.
The first European to find the islands was Dutch explorer Willem Schouten in 1616, but they remained unsettled by Europeans until they became part of the German protectorate of German New Guinea in 1884.
Following the outbreak of World War I, the Australian Naval and Military Expeditionary Force seized the islands in 1914 and Australia later received a League of Nations mandate for the islands. They remained under Australian control — interrupted only by Japanese occupation during World War II — until Papua New Guinea became independent in 1975.
