Kaysone Phomvihane (Lao: ໄກສອນ ພົມວິຫານ) (13 December 1920 – 21 November 1992) was the leader of the Lao People's Revolutionary Party from 1955 until his death in 1992. He also served as the first Prime Minister of the Lao People's Democratic Republic from 1975 to 1991 and then as President from 1991 to 1992.
Kaysone was born Nguyen Cai Song to a Vietnamese father named Nguyen Tri Loan, and a Vietnamese mother named Nang Dok. He had two sisters: Nang Souvanthong, living in Thailand and Nang Kongmany in the USA. He was born in Na Seng village, Khanthabouli district (now Kaysone Phomvihane District, Savannakhet Province), Laos.
Kaysone attended law school at University of Indochina in Hanoi, Vietnam, with Nouhak Phoumsavan. He dropped out of law school to fight the French colonialists who were in Vietnam. Later, he joined the Pathet Lao movement, which was also fighting the French colonialists.
He became an active revolutionary while studying in the Indochinese capital of Hanoi (now the capital of Vietnam) during the 1940s. The Lao People's Liberation Army (LPLA) was established by Kaysone Phomvihane on January 20, 1949. He was minister of defence of Resistance Government (of the Neo Lao Issara) from 1950. In 1955 he was instrumental in setting up the LPRP at Sam Neua in northern Laos, and subsequently served as the Pathet Lao leader, with Souphanouvong as its figurehead. In the years which followed, he led communist forces against the Kingdom of Laos and U.S. forces. After their victory he served as Prime Minister from the founding of the Lao PDR in 1975 until 1991 and later President until his death in 1992. He married Thongvinh Phomvihane.
Kaysone displayed expert skills in handling relations with Vietnam. The demarcation process started in 1977 and just finished in 2007. According to western journalist the Lao/Viet borderline is "very close" to the 1945 border between Laos and Tonkin and Annam, respectively.
According to Vatthana Pholsena, assistant professor of Southeast Asian Studies at the National University of Singapore and author of the book "Post-war Laos", Kaysone Phomvihane was the top policy maker in LPDR, and a strongman. He created Sekong province to honour the southern minority for their support in the war effort.
His younger son, Sanyahak Phomvihane, was elected to the LPRP Central Committee at the 8th LPRP Congress and became a Major General at the age of 40 in 2008. However, he suffered an early death, at the age of 45, on 19 July 2013. His elder son, Xaysomphone Phomvihane (born 10 October 1954) currently serves as President of the Lao Front for National Construction. His another son, Santiphap Phomvihane currently serves as Governor of Savannakhet Province
