 With Haidallah's ambitious political and social reform program undone by continuing instability, regime inefficiency and a plethora of coup attempts and intrigues from within the military establishment, the CMSN chairman turned increasingly autocratic, excluding other "junta" officers from power, and provoking discontent by frequently reshuffling the power hierarchy to prevent threats to his position.On December 12, 1984, Maaouya Ould Sid'Ahmed Taya deposed Haidallah and declared himself Chairman of the CMSN.Like other rulers before him, he promised a swift transfer to democracy, but then made little of these promises.
