This chapter examines the transnational political influence of the international black diaspora across the twentieth century, focusing on its impacts on Aboriginal Australia. It focuses on extensive study of the rise of organized Aboriginal political mobilization during the 1920's with the Australian Aboriginal Progressive Association (AAPA) and highlights the significance of international connections upon the directions and strategies employed by the early movement and its leaders. The chapter describes the influence and impact of Marcus Garvey, both in global terms and more specifically in relation to his impact on Australian Aboriginal political activism. It also considers broader transnational cultural exchange including the contact and support of international black musicians. Garvey's project with UNIA meant that future black leaders, including Malcolm X and Martin Luther King, would pay due recognition to Garvey's significance in the African American struggle. The message Garvey spread across the globe was one of strength, unity and cultural pride.
