The Social Democratic Federation was established as Britain's first organised socialist political party by H. M. Hyndman, and had its first meeting on June 7, 1881. Those joining the SDF included William Morris, George Lansbury and Eleanor Marx. However, Friedrich Engels, Karl Marx's long-term collaborator, refused to support Hyndman's venture. Many of its early leading members had previously been active in the Manhood Suffrage League. The SDF battled through defections of its right and left wings to other organizations during the first decade of the 20th Century before uniting with other radical groups to establish the Marxist British Socialist Party from 1911 until 1920.
