Advocates of pan-Africanism—i.e. "pan-Africans" or "pan-Africanists"—often champion socialist principles and tend to be opposed to external political and economic involvement on the continent. Critics accuse the ideology of homogenizing the experience of people of African ancestry. They also point to the difficulties of reconciling current divisions within countries on the continent and within communities in the diaspora. History As a philosophy, pan-Africanism represents the aggregation of the historical, cultural, spiritual, artistic, scientific, and philosophical legacies of Africans from past times to the present. Pan-Africanism as an ethical system traces its origins from ancient times, and promotes values that are the product of the African civilisations and the struggles against slavery, racism, colonialism, and neocolonialism. Coinciding with numerous New World slave insurrections (hallmarked by the Haitian Revolution), the end of the 19th century birthed an intercontinental pro-African political movement that sought to unify disparate campaigns in the goal to end oppression. Another important political form of a religious pan-Africanist worldview appeared in the form of Ethiopianism. In London, the Sons of Africa was a political group addressed by Quobna Ottobah Cugoano in the 1791 edition of his book Thoughts and Sentiments on the Evil of Slavery. The group addressed meetings and organised letter-writing campaigns, published campaigning material and visited parliament.

Modern pan-Africanism began around the start of the 20th century. The African Association, later renamed the Pan-African Association, was established around 1897 by Henry Sylvester Williams, who organized the First Pan-African Conference in London in 1900. The Pan-African Congress series of meetings followed the first Pan-African Conference in 1900 in London. A meeting of the Congress in 1919 in Paris (1st Pan-African Congress), 1921 in London (2nd Pan-African Congress), 1923 in London (3rd Pan-African Congress), 1927 in New York City (4th Pan-African Congress), and 1945 in Manchester (5th Pan-African Congress) advanced the issue of decolonisation in Africa. The Fifth Pan-African Congress was a significant gathering, which brought together anti-colonial activists from the African continent and the Diaspora. Women such as Amy Ashwood Garvey and Amy Jacques Garvey helped to organise the Congress meeting and played a crucial role in the conferences. With the independence of Ghana in March 1957, Kwame
