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.

Ali gave his followers a new sense of identity. Most of them wore a fez which set them apart from the typical urban black. Many were also bearded, and each one carried a membership card. Having a different religion from that of the typical ghetto black contributed further to their special sense of identity. Ali's teaching also made them feel that they had a special and unique heritage of which they could be proud. His emphasis on separatism instead of on integration struck a harmonious note with their disillusionment. Instead of leaving them in despair, it permitted them to face white America boldly.

In 1929 a power struggle broke out between Noble Drew Ali and Claude Green, one of his organizers. When Green was found murdered, the Chicago police charged Ali with the crime. While Ali was out on bond, he too died under mysterious circumstances. While some claimed that he had been beaten by the police, others said that he had been "mugged" by Green's followers. Before he was released on bail Ali wrote a letter from prison to his followers encouraging them to have faith in him and in their future. His letter bore distinctly messianic overtones. After assuring them that he had redeemed them, he concluded by extending to them his peace and by commanding them to love one another. His movement splintered after his death into innumerable competing factions.

In Detroit, sometime before 1930, a dark-skinned man appeared selling silk and raincoats. He said that he was W. D. Fard and that he had come from the Holy City of Mecca in order to save the American Negro. People generally described him as being unusually light-skinned for a Negro with perhaps an Oriental cast. Fard also taught that the American Negro was Islamic in origin and that he should return to his ancestral faith. Sometime in 1933 or 1934 he disappeared as mysteriously as he had come. While many believed that Fard and his movement must have been connected with Noble Drew Ali and the Moorish American Science Temple, the Black Muslims have always denied it.

Fard founded, in Detroit, Muslim Temple Number One, and he acquired a handful of devout followers. He insisted that the Muslims should refrain from eating pork, should pray facing the East, and should practice a daily washing ritual. Muslim members were reminded that their last names had been imposed upon them by the white man whom Fard equated with the Devil. It is the practice among Muslims to drop their Christian name and, until their true names will be revealed to them, to substitute the letter X for their last name symbolizing the unknown. Fard insisted that the first man had been a black man and that whites were a corruption of humanity. The days of the White Devil, he said, were numbered. Blacks should deliberately withdraw from white society in order not to be caught in its final destruction.

The Muslim's life was rigidly disciplined. There were temple services almost every evening. Individual behavior and dress were carefully dictated. Besides forbidding the eating of pork, devout Muslims were not allowed to drink alcohol or smoke tobacco. Relationships between men and women were extremely puritanical. Each temple had special groups to prepare young men and women for manhood and womanhood. The Fruit of Islam was the young men's group, and it was a semi-military defense corps aimed at developing a sense of manhood and the ability for self-defense. The common belief that the Fruit of Islam was preparing for racial aggression has never been substantiated. The Muslim Girls' Training Classes taught cooking, sewing, housekeeping, and etiquette.

After Fard's disappearance, the leadership passed on to Elijah Muhammed, formerly Elijah Poole, whom Fard had been grooming as his successor. Elijah Muhammed moved to Chicago and began Temple Number Two and established his headquarters there. The "Black Muslims", as well as other small, semi-religious, separatist groups, continued to exist unnoticed by the general public. When Malcolm Little, better known as Malcolm X, was converted to the "Nation of Islam", he gave the movement the organizational skill and the eloquence which it previously lacked. This brought it into national prominence.

Black Nationalism and the Negro Renaissance shared a strong sense of racial consciousness and racial pride. However, while the writers who expressed the spirit of the new Negro still believed in their future in America, the black nationalists enunciated a mood of alienation and despair. The Depression, which eroded the hopes of many Americans, hit the Negro unusually hard. It served to increase the level of bitterness in the Afro-American community as a whole.
