Hun Sen is a prominent Cambodian politician who served as the Prime Minister of Cambodia for over 38 years, making him one of the world's longest-serving leaders. Originally a Khmer Rouge commander, he defected in 1977 and became a key figure in the Vietnamese-backed government that ousted Pol Pot's regime. His long rule was marked by significant economic growth and stability following decades of conflict, but also drew criticism for authoritarianism and suppression of dissent. In 2023, he resigned from the premiership, orchestrating a power transfer to his son, Hun Manet, while retaining significant influence as President of the Senate.
