Knights of Labor, American labor organization, started by Philadelphia tailors in 1869, led by Uriah S. Stephens. It became a body of national scope and importance in 1878 and grew more rapidly after 1881, when its earlier secrecy was abandoned. Organized on an industrial basis, with women, black workers (after 1883), and employers welcomed, excluding only bankers, lawyers, gamblers, and stockholders, the Knights of Labor aided various groups in strikes and boycotts, winning important strikes on the Union Pacific in 1884 and on the Wabash RR in 1885.

(for which it was, although not responsible, condemned by the press) caused a loss of prestige and strengthened factional disputes between the craft unionists and the advocates of all-inclusive unionism. With the motto "an injury to one is the concern of all," the Knights of Labor attempted through educational means to further its aims—an 8-hour day, abolition of child and convict labor, equal pay for equal work, elimination of private banks, cooperation—which, like its methods, were highly idealistic. The organization reached its apex in 1886, when under Terence V. Powderly its membership reached a total of 702,000. Among the causes of its downfall were factional disputes, too much centralization with a resulting autocracy from top to bottom, mismanagement, drainage of financial resources through unsuccessful strikes, and the emergence of the American Federation of Labor. By 1890 its membership had dropped to 100,000, and in 1900 it was practically extinct.

Knights of Labor

First important national labour organization in the U.S. Founded in 1869 by Uriah Smith Stephens as the Noble Order of the Knights of Labor, it included both skilled and unskilled workers, and it proposed a system of workers' cooperatives to replace capitalism. To protect its members from employers' reprisals, it originally maintained secrecy. Under Terence V. Powderly (1879–93) it favoured open arbitration with management and discouraged strikes. National membership reached 700,000 in 1886. Strikes by militant groups and the Haymarket Riot caused an antiunion reaction that rapidly reduced the organization's influence. A splinter group left to form the AFL (later AFL-CIO).
