Since independence in 1960, Nigeria has played various significant roles in world
affairs beginning with her immediate neighbors in the West African sub region and the world at
large. Leadership and personality have been central in these dynamic roles. For instance,
between 1999 and 2007, Nigeria‟s foreign relations and domestic policies were creative and
eventful, which have been linked to the personality and leadership of Olusegun Obas anjo, the
president of Nigeria at that time. Utilizing secondary data, the paper shows that Obasanjo‟s
personality and leadership traits launched Nigeria from isolationism to diplomatic influence and
relevance in world affairs. The paper further submits that Nigeria earned a positive international
image, the removal of the pariah status as well as economic re-invigoration. It thus recommends
amongst others, the need for both current and future leaders of Nigeria to exhibit outstanding
personality and leadership in the face of festering socio-political as well as economic challenges.
By such unusual display of effective leadership, Nigeria will regain its position in effectively
contributing to global development and also record success in her national transformation
agenda.
