Howell lived abroad for a total of some twenty years in his early life, during which time he was arrested and jailed for his involvement with the UNIA because the organization's pro-black messages were viewed as threatening. After migrating to Panama and the United States, he eventually returned home in December 1932 at the age of 34 after being deported from the US. He was deported because of his involvement with the UNIA, which was perceived as threatening by the US government, due to the organization's messages of black power and anti-colonialism. Upon returning to his homeland, he decided to leave his family home and spread the word about Rastafarianism. This decision to break away from his home was due to a conflict between Howell and his family, presumably because of his controversial belief in the divine nature of Haile Selassie I of Ethiopia.
