The term 'Jamaican Sectarian' refers to the Rastafari movement, a religious and cultural movement that originated in Jamaica in the 1930s. The movement is based on the teachings of Marcus Garvey, a Jamaican political leader who advocated for the repatriation of African people to their ancestral homeland. The term 'Rasta' is derived from the name of the movement's spiritual leader, Haile Selassie I, who was crowned Emperor of Ethiopia in 1930. Rastafari followers believe in the divinity of Selassie and practice a lifestyle based on his teachings.
