The International Socialist Group (ISG) was a Trotskyist organisation in Britain. It was the British section of the Fourth International (FI) until 2009 when it dissolved into Socialist Resistance. The ISG was the result of the 1987 fusion of two organisations, the International Group and the Socialist Group. Former members of the Socialist League established the International Group in 1985. Sharp differences had developed within the Socialist League majority during the 1984-85 miners' strike. Initially, the FI recognised the International Group as individual members of the FI and the Socialist League as its section. The International Group and subsequently the ISG attracted several waves of ex-SL members into its organisation, beginning with a group of long time International Marxist Group leaders in 1985. It continued to win over established and emerging Socialist League minority tendencies and disaffected branches for several years. More information...
