Bismarck Archipelago

Bismarck Archipelago

The Bismarck Archipelago is a group of islands of the coast of New Guinea in the southwestern Pacific Ocean, belonging to Papua New Guinea.

The archipelago includes mostly volcanic islands, the most important of which are:

Admiralty Islands
Duke of York Islands
Mussau Islands
New Britain
New Hanover
New Ireland
Vitu Islands

The islands were discovered by Dutch explorer Willem Schouten in 1616, but remained unsettled by Europeans until they became part of the German protectorate of German New Guinea in 1884.

The Australians seized the islands in World War I and kept a League of Nations mandate until Papua New Guinea's independence, only interrupted by Japanese occupation during World War II.
