Rastafari, also known as Rastafarianism, is an Abrahamic religion that developed in Jamaica during the 1930s. Scholars of religion and related fields have classified it as both a new religious movement and a social movement. There is no central authority in control of the movement and much diversity exists among practitioners, who are known as Rastafari, Rastafarians, or Rastas. Vector Illustration Copyright BluedarkArt.
