Title: Timeline of the Irish War of Independence
Content:  This is a timeline of the Irish War of Independence (or the Anglo-Irish War ) of 1919–21. The Irish War of Independence was a guerrilla conflict and most of the fighting was conducted on a small scale by the standards of conventional warfare. Although there were some large-scale encounters between the Irish Republican Army and the state forces of the United Kingdom (Royal Irish Constabulary and Dublin Metropolitan Police paramilitary units—the Black and Tans and the Auxiliary Division—and the regular British Army), most of the casualties were inflicted in assassinations and reprisals on either side. The war began with an unauthorised ambush by IRA volunteers Dan Breen and Seán Treacy at Soloheadbeg in 1919 and officially ended with a truce agreed in July 1921. However, violence continued, particularly in the disputed territory of Northern Ireland, until mid-1922. In the rest of Ireland, the war was followed by the Irish Civil War between supporters and opponents of the Anglo-Irish Treaty.

The Confederation was essentially an independent state and was a coalition of all shades of Irish Catholic society, both Gaelic and Old English. The Irish Confederates professed to side with the English Cavaliers during the ensuing civil wars, but mostly fought their own war in defence of the Catholic landed class's interests. The Confederates ruled much of Ireland as a de facto sovereign state until 1649, and proclaimed their loyalty to Charles I. From 1642 to

Content:  Irish Civil War, in which Irish Free State, or "pro-treaty", forces proved victorious. The history of Northern Ireland has since been dominated by the division of society along sectarian faultlines and conflict between (mainly Catholic) Irish nationalists and (mainly Protestant) British unionists. These divisions erupted into the Troubles in the late 1960s, after civil rights marches were met with opposition by authorities. The violence escalated after the deployment of the British Army to maintain authority led to clashes with nationalist communities. The violence continued for 28 years until an uneasy, but largely successful peace was finally achieved with the Good Friday Agreement in 1998.
