Book excerpt: Here is the first full-length study to examine the changing academic debate on developments in African American history from the 1890s to the present. It provides a critical historiographical review of the most current thinking and explains how and why research and discourse have evolved in the ways that they have. Individual chapters focus on particular periods in African American history from the spread of racial segregation in the 1890s through to the postwar Civil Rights Movement and the Black Power Movement of the sixties and seventies.
