Republic of Bougainville

The Republic of the North Solomons, a republic and former autonomous state that existed for about six month before independence from Papua New Guinea (PNG).

History
On 1 September 1975, the North Solomons unilaterally declared independence from the Australian-administered territory of Papua and New Guinea, which itself was due to become independent on 16 September. In 1976 the Bougainvillese Army attacked the invading Australians and New Zealanders in a surprise attack. This was the turning point when Australia and New Zealand made a ceasefire in 1979.
