Africa is endowed with abundant natural resources and it has attracted development aid from the rich nations of the world. Despite these, the continent remains undeveloped. Different reasons have been attributed to the African development crisis among the modernist school and the dependency school. This study was undertaken to unravel the cause of the African underdevelopment. The paper pinpoints that corruption is the core reason behind African underdevelopment and it laid emphasis on corruption and underdevelopment interface in Nigeria. For Africa to break the impasse of underdevelopment, the paper calls for good governance and the establishment of special agencies to monitor all development projects undertaking by African countries.
