At the same time, the Provisional IRA, emerged from the 1969 rioting intending to launch an armed campaign against the Northern state. By 1972, their campaign was of considerable intensity, killing over 100 British soldiers in that year alone. Unlike the IRA campaign of the 1950s, this campaign was viewed as having considerable public support among Northern nationalists and for this reason, Irish governments did not introduce internment as they had previously, in the absence of a political settlement in Northern Ireland. The Irish government also refused to allow British and Northern Ireland security units to pursue Republican paramilitaries over the border into the Republic and arrested those soldiers or police who did enter its territory armed.
