Against the background of a changing world order, former colonial powers frequently challenged Pan-Africanism and reasonable arguments voiced in Pan-African congress petitions and speeches. In this book, Mano Delea traces Pan-Africanism from its roots in a time dominated by the necessity to engage to a time in which it increasingly was able to confront former colonial and imperial powers. In Pan-Africanism: Visions, Initiatives, and Transformations, 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 between 1900 and 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.
