In the past fifteen years African heads of state and the Organization of African Unity have striven with little success to unite liberation movements fighting the settlers and colonialists in their countries in Southern Africa. The first attempt was made by Kwame Nkrumah of Ghana and other leaders, and was directed at uniting the Pan-Africanist Congress and its rival African National Congress of South Africa soon after both were banned and forced into exile following the Sharpeville demonstrations. When leaders of both parties fanned out into the world to solicit support, some of the would-be supporters forced them into a makeshift marriage of convenience.
