Marcus Mosiah Garvey, Jr., ONH (17 August 1887-10 June 1940) was a Jamaican publisher, journalist, entrepreneur, and orator who was a staunch proponent of the Black nationalism and Pan-Africanism movements, to which end he founded the Universal Negro Improvement Association and African Communities League (UNIA-ACL). He founded the Black Star Line, part of the Back-to-Africa movement, which promoted the return of the African diaspora to their ancestral lands.
Prior to the twentieth century, leaders such as Prince Hall, Martin Delany, Edward Wilmot Blyden, and Henry Highland Garnet advocated the involvement of the African diaspora in African affairs. Garvey was unique in advancing a Pan-African philosophy to inspire a global mass movement and economic empowerment focusing on Africa known as Garveyism. Promoted by the UNIA as a movement of African Redemption, Garveyism would eventually inspire others, ranging from the Nation of Islam to the Rastafari movement.
