Throughout this period, the main paramilitary organisations began to form. 1972 was the most violent year of the conflict. In 1970 the Provisional IRA, was created as a breakaway from what then became known as the Official IRA (the Provisionals came from various political perspectives, though most rejected the increasingly Marxist outlook of the Officials and were united in their rejection of the Official's view that physical force alone would not end partition), and a campaign of sectarian attacks by loyalist paramilitary groups like the Ulster Defence Association (formed to co-ordinate the various Loyalist vigilante groups that sprung up) and others brought Northern Ireland to the brink of civil war. On 30 March 1972, the British government, unwilling to grant the unionist Northern Ireland government more authoritarian special powers, and now convinced of its inability to restore order, pushed through emergency legislation that prorogued the Northern Ireland Parliament and introduced direct rule from London. In 1973 the British government dissolved the Parliament of Northern Ireland and its government under the Northern Ireland Constitution Act 1973.
