Anti-corruption campaign among successive administration has been attempting to curb the hydra-headed monster and clog in the wheel of the development progress of developing countries at large and Nigeria in particular. Essentially, the poverty and menace of poor development programmes’ delivery, which Nigeria witnessed in the pre-1999 era made the Obasanjo Administration to fight the war headlong. The methodology adopted is qualitative with the usage of secondary data and observation as conscious citizens of the country who witnessed the activities of the administration against corrupt practices. This essay is therefore divided into introduction; a review of anti-corruption war; the success of institutional approach; salient lessons; conclusion and recommendations that centre on the promotion of entrepreneurship, traditional value system, honesty, sacrifice, selflessness, and discipline.
