The Pullman Strike was two interrelated strikes in 1894 that shaped national labor policy in the United States during a period of deep economic depression. First came a strike by the American Railway Union (ARU) against the Pullman factory in Chicago in spring 1894. When it failed, the ARU launched a national boycott against all trains that carried Pullman passenger cars. The nationwide railroad boycott that lasted from May 11 to July 20, 1894, was a turning point for US labor law. It pitted the American Railway Union (ARU) against the Pullman Company, the main railroads, the main labor unions, and the federal government of the United States under President Grover Cleveland. The strike and boycott shut down much of the nation's freight and passenger traffic west of Detroit, Michigan. The conflict began in Chicago, on May 11 when nearly 4,000 factory employees of the Pullman Company began a wildcat strike in response to recent reductions in wages. Most of the factory workers who built Pullman cars lived in the "company town" of Pullman just outside of Chicago. Jennie Curtis who lived in Pullman was president of seamstress union ARU LOCAL 269 gave a speech at the ARU convention urging people to strike. It was designed as a model community by its namesake founder and owner George Pullman.

The Pullman Company, founded by George Pullman, was a manufacturer of railroad cars in the mid-to-late 19th century through the first half of the 20th century, during the boom of railroads in the United States. Through rapid late-19th century development of mass production and takeover of rivals, the company developed a virtual monopoly on production and ownership of sleeper cars.
