Custom House Fire and Truce
Archived: 9 October 2026
In 1921, Ireland moved from intense War of Independence fighting towards truce and treaty, amid coercion, raids and executions. IRA engagements at Crossbarry and Tourmakeady maintained pressure, while the Custom House burning destroyed records but cost lives and arrests. May elections confirmed Sinn Féin’s southern mandate and established Northern Ireland’s unionist government. The 11 July truce ended principal IRA–Crown operations but not Belfast’s sectarian violence. London negotiations produced the December Anglo-Irish Treaty, creating a dominion Free State while retaining the Crown, partition and British naval facilities. Signed but unapproved, it deeply divided republicans, leaving border, constitutional and security questions unresolved.
