The prominent African leader during the decolonization of Africa was Kwame Nkrumah, who became the first Prime Minister and later the first President of Ghana after its independence from British colonial rule in 1957. Nkrumah was instrumental in advocating for Pan-Africanism and played a significant role in pushing for the liberation of other African nations from colonial powers. His vision of a unified Africa and his efforts to promote social and economic development were pivotal during the post-colonial era. Nkrumah's leadership and ideology inspired many other African leaders striving for independence and self-determination.
