Established in 1903, the Tariff Reform League (closely allied to the Imperial Tarrif Committee, the Birmingham based organisation which it eventually superseded) was set up as a protectionist pressure group, supporting, in particular, Joseph Chamberlain's proposal for Preferential Treatment with the Colonies. At its most active, the League was well organised and many local branches and a few women's sections were. The League went out of existence some time after the First World War. Its work of propaganda was taken up by other organisations in the 1920s, notably the Empire Industries Association.
