Lon Nol, Cambodian general and politician, 37th Prime Minister of Cambodia (died 1985)

Marshal Lon Nol was a Cambodian military officer and politician who served as Prime Minister of Cambodia twice, as well as serving repeatedly as defence minister and provincial governor. As a right-wing nationalist, he led the military coup of 1970 against Prince Norodom Sihanouk, abolished the monarchy, and established the short-lived Khmer Republic. Constitutionally a semi-presidential republic, Cambodia was de facto governed under a military dictatorship. He was the commander-in-chief of the Khmer National Armed Forces during the Cambodian Civil War and became President of the Khmer Republic on 10 March 1972. On 1 April 1975, as the only president of the republic 16 days before the Khmer Rouge captured Phnom Penh, Lon Nol fled to the United States, first to Hawaii and then to California, where he remained until his death in 1985.
