On January 30, 1972, the streets of Derry, Northern Ireland, ran red with blood. What began as a peaceful civil rights march against internment without trial ended in a massacre when British paratroopers opened fire on unarmed civilians, killing thirteen on the spot, with another dying later from his wounds. It was a day that shattered trust, fueled the IRA’s rise, and left a permanent stain on British-Irish relations. Today, we break down the events of Bloody Sunday, the cover-ups that followed, and the decades-long fight for justice. This is not just history—it’s a wound that still bleeds.
