Revisionist history or romance?
The troubles between catholic and protestant stared centuries before NI. In the early 1600s when Scotts and English were give land in ireland.
The first ira formed in 1909 (incidentally before northern ireland was formed) to fight the war and disbanded 1922
Various versions of the ira formed in 1969 (named official ira), another 1974 (irish national liberation army), another 1997 (real ira), (and several more small terrorist groups aligning themselves broadly with the larger groups)

Their goals were not democratic but terrorist and criminal
