Marcus Mosiah Garvey Sr. ONH was a Jamaican political activist, publisher, journalist, entrepreneur, and orator. He was the founder and first President-General of the Universal Negro Improvement Association and African Communities League, through which he declared himself Provisional President of Africa. Ideologically a black nationalist and Pan-Africanist, his ideas came to be known as Garveyism.
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.
