The anti-colonial leader best known for his vision of Pan-Africanism is Kwame Nkrumah. As the first President of Ghana and a prominent figure in the struggle against colonialism, Nkrumah strongly advocated for the unity of African states. He envisioned a politically united Africa that transcended tribal and national boundaries, believing collective action was vital for achieving political and economic independence. His ideas influenced various liberation movements across the continent, fostering a sense of solidarity and shared identity among Africans seeking freedom from colonial rule.
