The book you mentioned, “A classic look at the relationship between Emperor Haile Selassie I and the Rastafarians,” authored by Jah Ahkell and published by Research Associates, likely delves into the historical and spiritual connection between Emperor Haile Selassie I and the Rastafarian movement. This relationship is foundational to Rastafari, as followers consider Haile Selassie I to be the earthly embodiment of God (Jah) and a messianic figure.
