1925

A. Philip Randolph founded the Brotherhood of Sleeping Car Porters on August 25, 1925, organizing 12,000 Black Pullman porters — who called the porters collectively 'George' after founder George Pullman — against one of the country's largest employers of Black labor. Pullman Company used surveillance, firings, and its own company union to crush organizing. After a decade-long campaign, the BSCP won recognition in 1937, becoming the first predominantly Black union to win a contract from a major American corporation. The union became a pillar of the Civil Rights movement and financial sponsor of organizing.

The Universal Negro Improvement Association under Marcus Garvey reached peak membership of 4–6 million by 1921, with chapters in 40 countries, operating the Black Star Line shipping company, Negro Factories Corporation, and Black Cross Nurses. After Garvey's 1925 imprisonment for mail fraud — a prosecution orchestrated largely by J. Edgar Hoover's FBI using informants — the UNIA rapidly declined. Garvey was deported to Jamaica in 1927. While the UNIA's business ventures failed, Garvey's philosophy of Pan-African consciousness, Black pride, and self-determination profoundly influenced subsequent generations of Black nationalists including Malcolm X's father Earl Little, a UNIA organizer.

Marcus Garvey, leader of the Universal Negro Improvement Association with 4–6 million members, was convicted of mail fraud in 1923 related to stock sales for his Black Star Line steamship company. J. Edgar Hoover, then head of the FBI's Radical Division, built the case against Garvey beginning in 1919, deploying Black informants including James Wormley Jones. Garvey's sentence began in 1925. President Coolidge commuted his sentence in 1927, after which Garvey was deported to Jamaica. Hoover considered Pan-African organizing a national security threat.

Dr. Ossian Sweet, a Black physician, purchased a home in a white Detroit neighborhood in September 1925. When a white mob of hundreds surrounded the house, Sweet and friends fired shots from within, killing one white man. Sweet and ten others were charged with murder. The NAACP hired Clarence Darrow as defense counsel. After two trials, all defendants were acquitted by November 1926. The case established a precedent for Black self-defense and was a landmark NAACP legal campaign demonstrating the organization's growing power to contest violence through the courts.

Throughout the 1920s, Harlem tenants organized rent strikes against gouging landlords who charged Black renters 40–60% more than white renters for comparable units. Tenant organizations coordinated withholding of rent across multiple buildings. The rent party — a cultural institution where tenants threw paid parties to meet exorbitant rents — also became a form of community mutual aid. Organizations like the UNIA and local civic groups documented and publicized exploitation. These early rent strike efforts laid organizational groundwork for later tenant movements in the 1930s.
