Collected for the first time, the foundational contributions of a scholar and activist who shaped the study of Garveyism and pan-Africanism. This volume brings together Robert A. Hill's most important writings for the first time, highlighting his intellectual contributions to the history of pan-Africanism. A pioneering scholar and activist, a ground-breaking builder of pan-African archives, and the editor of the multivolume Marcus Garvey and Universal Negro Improvement Association Papers, Hill remains under-acknowledged for his influence on the field. This collection is a long-overdue testament to his legacy. Adam Ewing showcases Hill's ground-breaking writings on Garveyism, the pan-African, anticolonial movement that spread across the globe following World War I. Hill's essays trace Marcus Garvey's evolving thought and illuminate the resonance of the movement in the Caribbean and its diaspora, in the United States, and across sub-Saharan Africa. The volume also includes Hill's writings on diverse aspects of pan-Africanism, including the imposter figure in diaspora history, Cyril Briggs's African Blood Brotherhood, the Rastafarian movement, the fiction of George Schuyler, George Beckford and the Abeng collective in Jamaica, the theories of Walter Rodney, the life and thought of C.L.R. James, and the music of Bob Marley. This volume not only demonstrates Hill's intellectual praxis and its roots in his academic influences and personal experiences but also reveals the breadth, diversity, complexity, and centrality of the pan-African tradition in African diasporic politics and thought.
