The significance of Hubert Henry Harrison (1883–1927)—as a journalist, activist, and educator—lies in his innovation of radical solutions to grave injustices, especially the staggering luxury for the few alongside the crushing poverty for the many in the first few decades of the twentieth century. White mob violence continually haunted African American communities, while imperial conquest and world wars wrought wanton destruction upon entire nations of people. These conditions sparked a global political awakening to which Harrison gave voice as a leading figure in cutting-edge struggles for socialism, in the free love movement, and in the Harlem Renaissance. He also played a pivotal role in the rise of Marcus Garvey and the establishment of the largest international organization of Black people in modern history. Because of his fierce and fearless radicalism, however, he has been erased from popular memory. Hubert Harrison presents a historical restoration of Harrison's numerous intellectual and political breakthroughs. Offering a fresh interpretation of his contributions to social movements for economic, racial, and sexual liberation, Brian Kwoba's richly textured narrative highlights the startling and continued relevance of Harrison's visionary thinking across generations.
