The Army Comrades Association (ACA), later the National Guard, then Young Ireland and finally League of Youth, but better known by the nickname The Blueshirts (Irish:Na Léinte Gorma), was a far-right organisation in the Irish Free State in the early 1930s. The organisation provided physical protection for political groups such as Cumann na nGaedheal from intimidation and attack by the anti-Treaty IRA. Some of its members went on to fight for the Fascists in the Spanish Civil War.
