History of Papua New Guinea - Territory of New Guinea

Territory of New Guinea

The Commonwealth of Australia assumed a mandate from the League of Nations for governing the former German territory of New Guinea in 1920. It was administered under this mandate until the Japanese invasion in December 1941 brought about the suspension of Australian civil administration. Much of the Territory of New Guinea, including the islands of Bougainville and New Britain, was occupied by Japanese forces before being recaptured by Australian and American forces during the final months of the war (see New Guinea campaign).
