Kwame Nkrumah framed a model of African unity and development, which stood out insharp contrast to the Western model of capitalist development and neo-liberal democracy.Decades after his demise, the African Union which he co-founded with other Africanleaders, now espouses a model of development based on liberal democracy and marketprinciples, a radical break away from Nkrumahist thinking. This research addresses thefollowing two questions. First, "What principles constitute Nkrumah's model andideas on economic development and Pan African Unity?" Secondly, the paper asks,"What has accounted for the current shift from the Nkrumahist vision of Africa intothe neo-liberal model of development on the African continent?" The study issignificant because Africa still lacks its own model of development. It is a qualitativeresearch which looked into a number of writings, articles, and commentaries by Nkrumahhimself and other scholars. To conclude, the paper examines how Nkrumah's ideas canbe salvaged and utilized today into policies of political integration and economicdevelopment without necessarily pushing for a socialist and authoritarian state.
