Hun Sen

Samdech Hun Sen (/hʊn sɛn/; Khmer: ហ៊ុន សែន, UNGEGN: Hŭn Sên [hun saen]; born 5 August 1952) is a Cambodian politician and former military general who currently serves as the president of the Senate. He previously served as the prime minister of Cambodia from 1985 to 2023. Hun Sen is the longest-serving head of government in Cambodia's history. He is the president of the Cambodian People's Party (CPP), which has governed Cambodia since 1979, and has served as a member of the Senate since 2024. His full honorary title is Samdech Akeakmohasenapadey Techo Hunsen (Khmer: សម្តេច អគ្គមហាសេនាបតី តេជោ ហ៊ុន សែន, UNGEGN: Sâmdéch Âkkô Môha Sénéa Bâtei Téchoŭ Hŭn Sên [sɑmɗac ʔakkeaʔ mɔhaː senaː paɗəj tecoː hun saen]; meaning "Lord Prime Minister and Supreme Military Commander Hun Sen").

Born Hun Bunal, he changed his name to Hun Sen in 1972, two years after joining the Khmer Rouge as a soldier. He fought for the Khmer Rouge in the Cambodian Civil War and was a battalion commander in Democratic Kampuchea until defecting in 1977 and fighting alongside Vietnamese forces in the Cambodian–Vietnamese War. From 1979 to 1986 and again from 1987 to 1990, he served as Cambodia's foreign minister in the Vietnamese occupied government. At age 26, he was also the world's youngest foreign minister.

Hun Sen rose to the premiership in January 1985 when the one-party National Assembly appointed him to succeed Chan Sy, who had died in office in December 1984. He held the position until the 1993 UN-backed elections which resulted in a hung parliament, with opposition party FUNCINPEC winning the majority of votes. Hun Sen refused to accept the result. After negotiations with FUNCINPEC, Norodom Ranariddh and Hun Sen agreed to simultaneously serve as First and Second Prime Minister, until the coalition broke down and Sen orchestrated a coup d'état in 1997 which toppled Ranariddh. Between 1998 and 2023, Hun Sen led the CPP to consecutive and often contentious election victories, overseeing rapid economic growth and development, but also corruption, deforestation and human rights violations. In 2013, Hun Sen and the CPP were reelected with a significantly reduced majority amidst a resurgent opposition. Allegations of voter fraud and irregularities led to unprecedented anti-government protests. In 2018, he was elected to a sixth and final term in a largely unopposed poll after the Supreme Court dissolved the main opposition party, with the CPP winning every seat in the National Assembly. He led the country during the onset of the COVID-19 pandemic and Cambodia's third chairmanship of ASEAN; and, after the 2023 election formally announced his resignation as prime minister in favour of his son, Hun Manet. He remains as party leader and in 2024, was appointed president of the Senate, ensuring his continued influence over the country's politics.

Hun Sen has been prominent in communist, Marxist–Leninist, and now state capitalist and national conservative political parties, and although Khmer nationalism has been a consistent trait of all of them, he is thought to lack a core political ideology. He has been described as a "wily operator who destroys his political opponents" by The Sydney Morning Herald and as a dictator who has assumed highly centralized power in Cambodia and considerable personal wealth using violence and corruption, including a personal guard said to rival the country's regular army.
