As a truce to end the Irish War of Independence approached on 11 July 1921, police launched a raid against republicans in Belfast. The IRA ambushed the police patrol and killed an officer, prompting immediate and severe retaliation by Protestant loyalists against Catholic communities in west Belfast.
On 10 July 1921, loyalists attacked Catholic enclaves, burning homes and businesses, which ignited widespread rioting and gun battles between Protestant and Catholic communities and paramilitaries. Police also engaged in gun battles with republicans and some officers fired indiscriminately at Catholic civilians, resulting in 17 killed that day.
By the time the truce took effect at noon on 11 July, three additional people had been fatally wounded, bringing the total to 20 dead. Approximately 200 homes were destroyed or badly damaged, displacing around 1,000 residents, the majority of them Catholic, underscoring the deep sectarian divisions that would persist in Northern Ireland.
Political Outcome
Widespread sectarian violence resulted in 20 deaths and 1,000 people displaced; the truce ending the Irish War of Independence took effect at noon on 11 July 1921, halting but not resolving communal tensions in Belfast.
