Rejecting United Nations supervision, the Indonesian government under Suharto decided to settle the question of West Irian, the former Dutch New Guinea, in their favor. Rather than a referendum of all residents of West Irian as had been agreed under Sukarno, an "Act of Free Choice" was conducted 1969 in which 1,025 Papuan representatives of local councils were selected by the Indonesians. After training in Indonesian language they were warned to vote in favor of Indonesian integration with the group unanimously voting for integration with Indonesia. A subsequent UN General Assembly resolution confirmed the transfer of sovereignty to Indonesia.
West Irian was renamed Irian Jaya ('glorious Irian') in 1973. Opposition to Indonesian administration of Irian Jaya (later known as Papua) gave rise to small-scale guerrilla activity in the years following Jakarta's assumption of control.
