Operation Trikora was an combined Indonesian military operation which aimed to seize and annex the Dutch overseas territory of Netherlands New Guinea in 1961 and 1962. After negotiations, the Netherlands agreed on 15 August 1962 to hand over Western New Guinea to the United Nations.

When the rest of the Dutch East Indies became fully independent as Indonesia in December 1949, the Dutch retained sovereignty over western New Guinea, and took steps to prepare it for independence as a separate country. The Dutch and West Papuan leaders argued that the territory did not belong to Indonesia because the West Papuans were ethnically and geographically different from Indonesians, had always been administrated separately, and that the West Papuans did not want to be under Indonesian control. After its independence until 1961, Indonesia attempted to gain control of Western New Guinea through the United Nations without success. Since the Indonesian National Revolution, Indonesian nationalists had always regarded Western New Guinea as an intrinsic part of the Indonesian state. They also contended that Western New Guinea (Irian Barat) belonged to Indonesia and was being illegally occupied by the Dutch.
