For much of its existence, Nigeria was governed by the military. From 1960 to 2007, a total of forty-seven years, the military ruled for twenty-nine years. The remaining eighteen years was taken up by civilian rule. The search for a functional and cohesive Nigeria was a constant leitmotiv that ran throughout the period. This search is what has been termed nation-building. The federal government of Nigeria was confronted with important nation-building challenges between 1999 and 2007. Some of these nation-building challenges are those of democracy, corruption, federalism and aggressive ethno-regionalism. By 1999, when Nigeria’s Fourth Republic was inaugurated, most of these nation-building challenges were yet to be resolved. When Chief Olusegun Obasanjo became the first civilian president in the Fourth Republic in 1999, he was confronted with the task of creating a functional and cohesive Nigerian polity. Thus, the centralquestions that this paper addresses are:

1. What are the mechanisms the Olusegun Obasanjo administration used to tackle Nigeria's nation-building challenges between 1999 and 2007?2. What are the specific programmes the administration used in the nationbuilding process?3. What are the nation-building challenges that confronted Nigeria between1999 and 2007?
