Hun Sen solidified his influence in Cambodia by serving as the country's longest-serving head of government, holding the position of Prime Minister between 1985 and 2023. Born Hun Bunal in 1952, he evolved from a Khmer Rouge battalion commander into the central figure of the Cambodian People's Party, managing the state through decades of shifting geopolitical alliances and internal conflict.
Early life and political emergence
Born in the Peam Kaoh Sna Commune, Hun Sen was the third of six children. He moved to Phnom Penh at age 13 to attend a monastic school. In 1970, he joined the Khmer Rouge insurgency following the removal of Norodom Sihanouk. During his military service, he changed his name from Hun Bunal to Hun Samrach and finally to Hun Sen in 1972. He sustained a permanent eye injury while fighting during the fall of Phnom Penh.
