Garvey was born to a moderately prosperous Afro-Jamaican family in Saint Ann's Bay, Jamaica, and apprenticed into the print trade as a teenager. Working in Kingston, he became involved in trade unionism before living briefly in Costa Rica, Panama, and England. Returning to Jamaica, he founded UNIA in 1914. In 1916, he moved to the United States and established a UNIA branch in New York City's Harlem district. Emphasising unity between Africans and the African diaspora, he campaigned for an end to European colonial rule across Africa and the political unification of the continent. He envisioned a unified Africa as a one-party state, governed by himself, that would enact laws to ensure black racial purity. Although he never visited the continent, he was committed to the Back-to-Africa movement, arguing that some people of African descent should migrate there. Garveyist ideas became increasingly popular and UNIA grew in membership. However, his black separatist views—and his relations with white racists such as the Ku Klux Klan (KKK) to advance their shared interest in racial separatism—divided Garvey from other prominent African-American civil rights activists such as W. E. B. Du Bois who promoted racial integration.
