The Luanda Trial was a trial held in Luanda, Angola, in June 1976 during the Angolan Civil War. Thirteen Western mercenaries were sentenced to either long prison terms or execution by firing squad.
Angola had gained its independence from Portugal on 11 November 1975, but the new country was immediately immersed in a three-sided civil war. The Popular Movement for the Liberation of Angola (MPLA) was supported by the Soviet Union and Cuba, while the United States and some of its allies backed the National Liberation Front of Angola (FNLA) and the National Union for the Total Independence of Angola (UNITA).
Thirteen mercenaries fighting for the FNLA – nine British, three American and one Irish – were captured by MPLA forces by mid-February 1976. On May 26, they were indicted by the People's Revolutionary Court in Luanda.
