Against the background of a changing world order, colonial powers frequently challenged Pan-Africanism and the reasonable arguments voiced in Pan-African Congresses. In Pan-Africanism: Visions, Initiatives, and Transformations, Mano Delea highlights how Pan-Africanism moved its epicenter, as the circumstances of world politics changed, from the Diaspora to Africa, where it was transformed and institutionalized. Unlike other research done on Pan-Africanism, Delea offers three new additions to this academic research by addressing and analyzing the responses of leading historical newspapers to the Pan-African Congresses from 1900 to 1945, examining the transformation of and division between Pan-Africanism as a social movement and as an institutionalized phenomenon, and discussing the epistemologies and knowledge production within Pan-Africanism throughout its history.
