The troubles in Northern Ireland rolled grimly on for almost 30 years from the late 1960s until the onset of the current shaky peace process. In that time, the conflict never strayed far off the news schedules of the world's media.

This is an account of what happened in the Northern Ireland conflict, and why, told by award-winning Ireland Correspondent for the "Independent", David McKittrick, and historian David McVea.
