Famous former Irish Regiments
Prior to 1922 and the foundation of the Irish Free State, many Irish soldiers served with distinction in regiments of the British Army. Among the regiments that disappeared on independence included:
The modern Irish Army is descended from the Irish Republican Army that fought for independence, and formed the initial Irish Free State Force under General Michael Collins, fighting on the pro-treaty side in the Irish Civil War. It included many former National Volunteers who served in Irish Regiments in World War 1, rather than the units that fought under the British Crown.
