He was
Minister of Finance from July 1977 to March 1979. He had a short term as the Governor of
Central Bank of Mauritania in summer 1978. He was first appointed by
Col. Mohamed Khouna Ould Haidallah of the
Military Committee for National Salvation (CMSN), on December 12, 1980, to replace Haidallah himself. Sid'Ahmed, who was not a military man, was to lead the return to civilian government. On April 25, 1981, less than five months later, Sid'Ahmed was again dismissed, after Col. Mohamed Khouna had decided to reinstate military rule. This came as a result of the March 16 attempt at a
coup d'état by the
Alliance for a Democratic Mauritania (AMD). His successor,
Col. Maaouya Ould Sid'Ahmed Taya, on 12 December 1984
depose Col. Mohamed Khouna and himself rule the country until 2005. Sid'Ahmed died in
Spain in 2017. ==References==
