Although Langston Hughes had been confident that the American dream could be made to include his people, thousands upon thousands of other Afro-Americans, especially among the lower classes, were extremely dubious. In 1916, Marcus Garvey came to Harlem, and before long his Universal Negro Improvement Association had opened chapters in urban centers all across the nation. As mentioned previously, Garvey did not believe that blacks could be taken into American society. Hundreds of thousands, who apparently agreed with him, followed his banner. Whatever was the actual number of members of the U.N.I.A., the movement gained more grass-roots support than had any other organization in Afro-American history. While the nation was willing to tolerate the Afro-American folk spirit, the people, themselves, did not believe that they would be accepted. Although Garvey's movement was by far the largest black nationalist organization in America, it was not the only one. In Chicago, Grover Cleveland Redding was preaching a Back-to-Africa philosophy of his own. He organized the Abyssinian Movement and urged Negroes living on the south side of Chicago to return to Ethiopia. On Sunday, June 20, 1920, Redding led a parade through the Chicago streets. He sat astride a white horse and wore what he claimed was the costume of an Abyssinian prince. At the corner, of East 25th Street and Prairie Avenue he stopped the procession, poured a flammable liquid on an American flag, and burned it. A Negro policeman, who attempted to break up the demonstration, was shot by one of Redding's followers. In the course of the melee, a white storekeeper and a white soldier were killed. Redding and another Negro were later executed for their part in the affair. In 1925 Noble Drew Ali came to Chicago and established the Moorish American Science Temple. Actually, he had previously attempted to organize other temples in New Jersey, Pennsylvania, and Michigan. He claimed that American Negroes were of Moorish descent and, instead of being really black, were olive-hued. His movement had a banner which carried a Moorish star and crescent on a field of red. He also claimed that American Negroes, being Moors, had an Islamic heritage rather than a Christian one, and he endeavored to spread his particular version of that faith throughout the Afro-American community. By 1927 Ali had established branches in Pittsburgh, Detroit, Philadelphia, Kansas City, Lansing, and elsewhere. He wrote his own version of the Koran which combined passages from the Moslem Koran, the Christian Bible, and some of the writings of Marcus Garvey.
