The Crumlin-Drimnagh feud is a feud between rival criminal gangs in south inner city Dublin, Ireland. The feud began in 2000 when a drugs seizure led to a split in a gang of young criminals in their late teens and early twenties, most of whom had grown up together and went to the same school. The resulting violence has led to 16 murders and scores of beatings, stabbings, shootings and pipe bomb attacks.
