Leonard Percival Howell (June 16, 1898 – February 25, 1981), also known as The Gong or G.G. Maragh (for Gong Guru), was a Jamaican religious figure. According to his biographer Hélène Lee, Howell was born into an Anglican family. He was one of the first preachers of the Rastafari movement (along with Joseph Hibbert, Archibald Dunkley, and Robert Hinds), and is known by many as The First Rasta.
Born in May Crawle River, Jamaica, Howell left the country as a youth, traveling to many places, including Panama and New York, and returned in 1932. He began preaching in 1933 about what he considered the symbolic portent for the African diaspora—the crowning of Tafari Makonnen as Emperor Haile Selassie I of Ethiopia. His preaching asserted that Haile Selassie was the "Messiah returned to earth," and he published a book called The Promised Key. Although this resulted in his being arrested, tried for sedition, and imprisoned for two years, the Rastafari movement grew. Over the following years, Howell came into conflict with all the establishment authorities in Jamaica: the planters, the trade unions, established churches, police, and colonial authorities. Howell was seen as a threat largely due to the anti-colonial message of the Rastafarian movement, which he was perpetuating along with the sermons promoting the idea of a positive black racial identity. Local ruling elites were uneasy with Howell’s popular call for black people to take a stand. Colonial authorities hoped to quell Howell’s growing movement early so as to snuff out support early on. As his following grew, the threat of Howell's core beliefs in the power of black people to overcome white oppression and his movement expanded to become an international concern given his strong messages of black liberation and Pan-Africanism that resonated with blacks across the globe.
