what was the main cause of the irish civil war
Irish Civil War The civil war was waged between two opposing groups, Irish republicans and Irish nationalists, over the Anglo-Irish Treaty. The forces of the Provisional Government (which became the Free State in December 1922) supported the Treaty, while the Republican opposition saw it as a betrayal of the Irish Republic (which had been proclaimed during the Easter Rising). Many of those who fought on both sides in the conflict had been members of the Irish Republican Army (IRA) during the War of Independence.
