Many a reggae musician is a Rasta, which is a term used to describe someone who follows the Rastafari movement. The Rastafari movement is a religious and social movement that originated in Jamaica in the 1930s. It is based on the teachings of Marcus Garvey, an African-American civil rights leader, and is closely associated with reggae music. Rastas are known for their dreadlocks, their use of marijuana, and their spiritual beliefs.
