Jah Rastafari comes from the Rastafari movement that emerged in Jamaica in the 1930s. Ras Tafari was the pre-coronation name of Ethiopian emperor Haile Selassie I, crowned in 1930 and regarded by followers as God incarnate, while Jah is a shortened form of Jehovah. Reggae artists in the 1970s carried the praise around the world, making it a familiar chant far beyond the faith. Online it survives as a short soundboard clip, dropped into memes and edits whenever a calm, spiritual reggae mood is needed.
