Answer:
Rastafari is more a movement than a formal religion, founded by Marcus Garvey in the 1920's.
"There is significant variation within the Rastafari movement and no formal organization. Some Rastafarians see Rasta more as a way of life than a religion. But uniting the diverse movement is belief in the divinity and/or messiahship of Ethiopian Emperor Haile Selassie I, the influence of Jamaican culture, resistance of oppression, and pride in African heritage."

"Leonard Howell emerged as an early leader of the movement. He taught six fundamental Rastafarian principles: (1) hatred for the White race; (2) the complete superiority of the Black race; (3) revenge on Whites for their wickedness; (4) the negation, persecution, and humiliation of the government and legal bodies of Jamaica; (5) preparation to go back to Africa; and (6) acknowledging Emperor Haile Selassie as the Supreme Being and only ruler of Black people. Many of these principles were subsequently abandoned as the Rastafarian movement developed." [religionfacts.com]
