While students are encouraged to define their own boundaries for their research projects, this guide is concerned primarily with the modern African Diaspora and especially with the fifth diasporic stream, or what is discussed in these pages as the Atlantic African Diaspora. These pages are also concerned with the sixth diasporic stream to the extent that it overlaps temporally or geographically with the Atlantic African Diaspora, as in studies of emancipation, postemancipation, or twentieth century black internationalism/linkages across the Atlantic littoral. But the Atlantic African Diaspora is not simply the study of slavery or the study black life in particular parts of the Americas. It seeks to explore the linkages and disjunctures among black populations all around the Atlantic littoral and in doing so explore the creation of racial gendered hierarchies that in many ways becomes the “modernity” we take for granted today.
