Linden Forbes Sampson Burnham (20 February 1923–6 August 1985) was a Guyanese political leader and leader of Guyana from 1964 until his death, as the Prime Minister from 1964 to 1980 and as President from 1980 to 1985.
He was married to Viola Burnham, who was also involved in politics. He had three children, Roxane, Annabelle, and Francesca from his first marriage to Bernice Lataste. His second marriage to Viola produced two daughters, Melanie and Ulele and later a son Kamana (adopted).
In 1955, there was a split in the PPP between Burnham and Jagan. As a result, Burnham went on to form the People's National Congress in 1958 entering its first election under that name in 1961.
Burhnam at first pursued moderate policies. However, one of his first acts upon independence was a sweeping "National Security Act" giving the police the power to search, seize and arrest anyone virtually at will. He won full power in 1968, although the elections were condemned by many as fraudulent due to a large number of voter irregularities (such as questionable numbers of overseas voters on the rolls). In 1970, he veered sharply to the left and established strong relations with Cuba, the Soviet Union and other communist countries. On February 23 of that year, he declared Guyana a "co-operative republic." Adopting a policy of autarky, he banned all forms of imports into the country, including flour and varieties of rice. Burnham also nationalized the major industries that were foreign owned and controlled, reducing the private sector's share of the economy to 10 percent by 1979. Burnham's policies acted as a catalyst for the mass exodus in the 1980s that saw the country's population reduced significantly.
In 1974, Burnham declared the PNC to be paramount and socialist. He passed a referendum in 1978 which made it harder for his party to lose power, but there was wide evidence that the referendum was tainted by fraud. In 1980, the constitution was changed to make the president chief executive officer. He was elected president that year in elections condemned as fraudulent by international observers.
Guyana remained a member of the Commonwealth of Nations and Burnham's former foreign minister, Shridath Ramphal, became the organization's secretary general and ensured that no criticism was leveled at Burnham and his policies.
Burnham remained President of Guyana until his death. He died on August 6 1985 after undergoing throat surgery in Georgetown Hospital. His body was mummified by the Laboratory of the Lenin Mausoleum in Moscow.
