Everyday life during the Troubles — the Troubles Local people walking past a British soldier on guard in Northern Ireland, August 1969.

The march in Derry on January 30, 1972, was organized by the Northern Ireland Civil Rights Association (NICRA) to protest the British government’s policy of internment without trial.1

Following the introduction of internment in August 1971, which allowed authorities to detain suspected members of the Irish Republican Army (IRA) without trial, tensions in Northern Ireland escalated significantly. The overwhelming majority of those arrested under this policy were nationalists, fueling widespread grievances against the government.23

Although the demonstration was declared illegal, approximately 10,000 people gathered to march in opposition to these security measures. The event, which became known as Bloody Sunday, turned violent when British paratroopers opened fire on the demonstrators. A 2010 government inquiry, the Saville Report, later concluded that none of the victims had posed a threat to the soldiers and that the shooting was entirely unjustified.12
