On April 13, 1922, the Anti-Treaty Irish Republican Army (IRA), under the command of Rory O'Connor, occupied the Four Courts in Dublin. This action was a direct challenge to the newly formed Provisional Government of the Irish Free State, which had signed the Anglo-Irish Treaty. The occupation escalated tensions between pro- and anti-Treaty factions, ultimately leading to the Battle of Dublin in June 1922 and the outbreak of the Irish Civil War. The event marked a critical turning point in Ireland's struggle for independence and self-governance.
