Norodom Sihanouk (ˈsiːhənʊk; នរោត្តម សីហនុ, UNGEGN: Nôroŭttâm Seihânŭ, ALA-LC: Narottam Sīhanu nɔroːɗɑm səjhanuʔ; 31 October 192215 October 2012) was a Cambodian statesman, Sangkum and FUNCINPEC politician, film director, and composer who led Cambodia in various capacities throughout his long career, most often as both King and Prime Minister of Cambodia. In Cambodia, he is known as Samdech Euv (សម្តេចឪ, UNGEGN: Sâmdéch Âu, ALA-LC: Samṭec Ýu sɑmɗac ʔɨw; meaning "King Father"). During his lifetime, Cambodia was under various regimes, from French colonial rule (until 1953), a Japanese puppet state (1945), an independent kingdom (1953–1970), a republic (1970–1975), the Khmer Rouge regime (1975–1979), a Vietnamese-backed communist regime (1979–1989), a transitional communist regime (1989–1993) to eventually another kingdom (since 1993).
Sihanouk was the only child of Prince Norodom Suramarit and Princess Sisowath Kossamak, daughter of King Sisowath Monivong. When his grandfather Monivong died in 1941, Sihanouk became king amidst French colonial rule. After the Japanese occupation of Cambodia during World War II, he secured Cambodian independence from France in 1953. He abdicated in 1955 and was succeeded by his father, Suramarit, so as to directly participate in politics. Sihanouk's political organization Sangkum won the general elections that year and he became prime minister of Cambodia. He governed the country under one-party rule and suppressed political dissent. After his father died in 1960, Sihanouk assumed a new position as Chief of State of Cambodia.
Officially neutral in foreign relations, Sihanouk was closer to the communist bloc in practice. The 1970 Cambodian coup d'état ousted him and he fled to China and North Korea, forming a government-in-exile and a resistance movement there. He encouraged Cambodians to fight the new government and backed the Khmer Rouge during the Cambodian Civil War. He returned as figurehead head of state after the Khmer Rouge's victory in 1975. His relations with the new government soured and in 1976 he resigned.
