Catholics. By mid-1969 the violence in Northern Ireland exploded. Consistent with their new political ideology, the IRA declined to intervene. By late August, the British government had to intervene and declare a state of emergency, sending a large number of troops into Northern Ireland to stop the intercommunal violence. Initially welcomed by some Catholics as protectors, later events such as Bloody Sunday and the Falls Road curfew turned many against the British Army. 1970–1985 Divisions began to emerge in the Republican movement between leftists and conservatives. The leader of the IRA, Cathal Goulding believed that the IRA could not beat the British with military tactics and should turn into a workers' revolutionary movement that would overthrow both governments to achieve a 32-county socialist republic through the will of the people (after WWII the IRA no longer engaged in any actions against the Republic). Goulding also drove the IRA into an ideologically Marxist–Leninist direction which attracted idealistic young supporters in the Republic, but alienated and angered many of the IRA's core supporters in the North. In particular, his decision to regard the UVF as deluded rather than as the enemy, was anathema to traditionalists and those who were its potential victims. The argument led to a split in 1970, between the Official IRA (supporters of Goulding's Marxist line) and the Provisional IRA (also called Provos, traditional nationalist republicans). The Provos were led by Seán Mac Stíofáin and immediately began a large scale campaign against British state forces and economic targets in Northern Ireland. The Official IRA were also initially drawn into an armed campaign by the escalating communal violence. In 1972, the Official IRA declared a cease-fire, which, apart from feuds with other republican groups, has been maintained to date. Nowadays the term 'Irish Republican Army' almost always denotes the Provisional IRA. Throughout the 1970s and 1980s the conflict continued claiming thousands of lives, with the UVF (and other loyalist groups) extending attacks into the Republic of Ireland and the IRA launching attacks on targets in England. However some things slowly began to change. In the 1980s Provisional Sinn Féin (the Provisional IRA's political wing) began contesting elections and by the mid-1990s was representing the republican position at peace negotiations. In the loyalist movement splits occurred, the Ulster Unionist Party made tentative attempts to reform itself and attract Catholics into supporting the union with Britain, while the radical Democratic Unionist Party
