Stephens argues that the global black political consciousness she identifies was constituted by both radical and reactionary impulses. On the one hand, Garvey, McKay, and James saw freedom of movement as the basis of black transnationalism. The Caribbean archipelago—a geographic space ideally suited to the free movement of black subjects across national boundaries—became the metaphoric heart of their vision. On the other hand, these three writers were deeply influenced by the ideas of militarism, empire, and male sovereignty that shaped global political discourse in the early twentieth century. As such, their vision of transnational blackness excluded women’s political subjectivities. Drawing together insights from American, African American, Caribbean, and gender studies, Black Empire is a major contribution to ongoing conversations about nation and diaspora.
