Stevens was born in Moyamba, Sierra Leone. He was the leader of the All Peoples Congress party. He was briefly prime minister in March 1967 before being deposed in a coup d'etat, but he returned to that office on April 26, 1968. He served as prime minister until April 21, 1971, at which point a new constitution made the country a republic and Stevens was made president.
In 1978, Sierra Leone became a one-party state under the All Peoples Congress. Stevens retired as president in favor of his successor, Joseph Momoh, on November 28, 1985. He died in the capital, Freetown.
Siaka Probyn Stevens (24 August 1905–29 May 1988) was prime minister and, later, president of the Republic of Sierra Leone.
PresidentStevens served as Chairman of the Organization of African Unity (OAU) from 1 July 1980 to 24 June 1981, and engineered the creation of the Mano River Union, a three country economic federation of Sierra Leone, Liberia, and Guinea.
Stevens retired from office at the end of his term on 28 October 1985.
SiakaStevens sought to open the ranks of the party to all sectors of the community and to maintain a rough balance between ethnic groups, academics, clerics, businessmen and traditional rulers.
The conviction and possible imprisonment, of SiakaStevens then could have spelt the end of the A.P.C. The solemn state funeral that was accorded him at his death was a fitting tribute to the contribution he made to the development of Sierra Leone.
