Examines the UN mandate over East Timor, established pursuant to a UN Security Council resolution in 1999. Provides an evaluation of the UN Transitional Administration in East Timor and summarizes the country’s history, emphasizing the period following Portugal’s colonial departure in 1974 and the ensuing political conflict between the Timorese Democratic Union (UDT) and the Revolutionary Front of Independent East Timor (FRETIUN). The author also discusses the intervention of neighboring Indonesia, which ended with the implementation of the UN administration in October 1999.
