conference on Irish labour history held at an Irish university in 1974. Daly became active in the Northern Ireland civil rights movement following the introduction of internment without trial of suspected IRA members in 1972 by Westminster officials at the request of Prime Minister of Northern Ireland Brian Faulkner. She was active in the Northern Ireland Civil Rights Association (NICRA) and the Northern Resistance Movement (NRA), becoming involved in the former when she moved to Belfast; Daly subsequently joined the National Democratic Party (NDP), and its successor, the Social Democratic and Labour Party (SDLP). As a member of the SDLP she butted heads with John Hume and opposed advocacy for increased private home ownership rather than extended state housing. At the first SDLP annual conference, Daly led opposition to a motion condemning all political violence that was proposed by Hume. The rapid escalation of violence in Northern Ireland during this period, in particular, the killing of 14 civil rights marchers by members of 1 PARA in Derry on 14 January 1972 in what later became known as "Bloody Sunday" further radicalised her. After Bloody Sunday, she left the SDLP and joined Sinn Féin. During her political career, Daly, in line with many Irish republicans, opposed the two nations theory which held that Ulster Protestants constituted a distinct Irish nation. She also joined the Prisoners' Relatives Action Committee (PRAC), the National Hunger Strike Committee (NHSC) and the Murray Defence Committee (MDC), the latter of which successfully prevented the anarchist couple Marie and Noel Murray from being executed after they were convicted of murder and sentenced to death in June 1976 for murdering Garda Síochána officer Michael Reynolds. During the campaign to prevent the Murrays from being executed, Daly worked with Seamus Costello. In 1977, Daly and her partner left Sinn Féin over the party's advocacy of an Irish federation of four self-governing provinces. They were recruited in August 1977 to the IRSP by Costello, and co-opted to its Árd Chomhairle or governing body just before Costello's assassination on 5 October 1977, allegedly by the Official IRA. In February 1978 Miriam Daly was elected chair of the IRSP. Some later IRSP/INLA material describes Daly as a 'volunteer', but she was never a member of the Irish National Liberation Army, the IRSP's military wing. In 1974 the Dalys, who had received death threats, moved from their home in Stranmillis, close to Queen's University
