Rastafari, sometimes termed Rastafarianism, is an Abrahamic religion. Classified as a new religious movement, it developed in Jamaica during the 1930s. It lacks any centralised authority and there is much heterogeneity among practitioners, who are known as Rastafari, Rastafarians, or Rastas.
Rastafari refer to their beliefs, which are based on a specific interpretation of the Bible, as "Rastalogy". Central is a monotheistic belief in a single God—referred to as Jah—who partially resides within each individual. The former emperor of Ethiopia, Haile Selassie, is given central importance. Many Rastas regard him as an incarnation of Jah on Earth and as the Second Coming of Christ. Others regard him as a human prophet who fully recognised the inner divinity within every individual. Rastafari is Afrocentric and focuses its attention on the African diaspora, which it believes is oppressed within Western society, or "Babylon". Many Rastas call for the resettlement of the African diaspora in either Ethiopia or Africa more widely, referring to this continent as the Promised Land of "Zion". Other interpretations shift focus on to the adoption of an Afrocentric attitude while living outside of Africa. Rastas refer to their practices as "livity". Communal meetings are known as "groundations", and are typified by music, chanting, discussions, and the smoking of cannabis, the latter being regarded as a sacrament with beneficial properties. Rastas place emphasis on what they regard as living 'naturally', adhering to ital dietary requirements, allowing their hair to form into dreadlocks, and following patriarchal gender roles.
Rastafari originated among impoverished and socially disenfranchised Afro-Jamaican communities in 1930s Jamaica. Its Afrocentric ideology was largely a reaction against Jamaica's then-dominant British colonial culture. It was influenced by both Ethiopianism and the Back-to-Africa movement promoted by black nationalist figures like Marcus Garvey. The movement developed after several Christian clergymen, most notably Leonard Howell, proclaimed that the crowning of Haile Selassie as Emperor of Ethiopia in 1930 fulfilled a Biblical prophecy. By the 1950s, Rastafari's counter-cultural stance had brought the movement into conflict with wider Jamaican society, including violent clashes with law enforcement. In the 1960s and 1970s it gained increased respectability within Jamaica and greater visibility abroad through the popularity of Rasta-inspired reggae musicians like Bob Marley. Enthusiasm for Rastafari declined in the 1980s, following the deaths of Haile Selassie and Marley.
