Sorie Ibrahim Koroma

After the 1967 coup d'état by David Lansana and the return to civilian control in 1968, Koroma became the Minister of Trade and Industry in Siaka Stevens' first cabinet. From 1968 until 1985, Koroma served various functions in the government, including Minister of Agriculture and Natural Resources (1969–1971), Vice-President (1971–1985) and Prime Minister (1971–1975), Minister of Finance (1975–1978). He would continue in that position until 1978, when he was appointed First Vice-President after the APC declared itself the only legal party. Koroma was the First Vice President until he retired from politics. He went to care more directly for his palm oil plantation near his birthplace in Port Loko.

One of Sierra Leone’s most vibrant political figures, Sorie Ibrahim Koroma was born in Port Loko, Maforki Chiefdom, Port Loko District in the Northern province of British Sierra Leone. He was one of the 13TH member's of the APC after it was formed on March 20th 1960. Sorie Ibrahim Koroma's father was a member of the Mandingo ethnic group of Guinean descent, and he died when Koroma was just a little boy. After the death of his father, his mother, Ya Iye Wureh, married to an ethnic Temne chief named Bai Bockarie Dumbuya, the nephew of Alikali Mela (who was then Paramount Chief of Port Loko District).

In 1960, he was member of the All People's Congress (APC), which has since been one of the premier political parties in the country. In 1962, Koroma was elected as a Member of Parliament to the Parliament of Sierra Leone representing a district of Freetown, to which he was re-elected in the 1967 election

After completing his secondary education, S I Koroma, who had a fierce determination to succeed in life, landed a job with the Sierra Leone Government Co-operative Department. He worked there from 1951 to 1958 and took a course during that period at the Cooperative College, Ibadan, Nigeria. On his return home, he resigned from Government Service to set up his own private business. He fared well in the transportation business and within a short time became Secretary General of the Sierra Leone Motor Transport Union.
