During the late 1970s and early 1980s, the RCG became heavily involved in support for the Irish national liberation struggle, working with the Prisoners Aid Committee, Sinn Féin and the Troops Out Movement (TOM), and focusing particularly on support for Irish republican prisoners held in British prisons. The analysis which the RCG developed through this work, on the role of national liberation movements in opposing imperialism, laid the foundations for much of its later positions, and its relationship to the rest of the British left. Unlike many other left organisations, the RCG consistently argued that British troops had no progressive role to play in Ireland, and called for total support for the Republican movement in the struggle against British imperialism. Their involvement with the prisoner support groups established a tradition of outspoken support for prison struggles which has continued to the present, with a page of every issue of their newspaper dealing with prison conditions and struggles. In 1990, when prisoners at Strangeways (see 1990 Strangeways Prison riot) took over the prison in protest at conditions, the RCG was active together with other groups supporting them on the outside, and later published a book, 'Strangeways: A Serious Disturbance', largely written by prisoners and former prisoners.
