Industrial Workers of Great Britain

The Industrial Workers of Great Britain was a group which promoted industrial unionism in the early 20th century.

The Industrial Workers of the World (IWW) was founded in Chicago in 1905. It called for industrial unionism and aimed to organise workers in all industries, and many of its activists were members of the Socialist Labor Party of America. The British Socialist Labour Party had been founded in 1903 by Scottish supporters of Daniel de Leon, a leading figure in the American SLP and the IWW. In 1906, the British party formally adopted a policy of industrial unionism.
