Irish Republic

The Irish Republic was a revolutionary state that declared its independence from the United Kingdom of Great Britain and Ireland in January 1919. The Republic claimed jurisdiction over the whole island of Ireland, but by 1920 its functional control was limited to only 21 of Ireland's 32 counties, and British state forces maintained presence across much of the north-east, as well as Cork, Dublin and other major towns.

Its origins date back to the Easter Rising of 1916, when Irish republicans seized key locations in Dublin and proclaimed an Irish Republic. The insurrection was crushed, but the survivors united under a reformed Sinn Féin party to campaign for a republic. The party won a clear majority of largely uncontested seats in the 1918 general election, and formed the first Dáil of Ireland in Dublin on 21 January 1919. Republicans then established a government, a court system and a police force. At the same time, the Irish Volunteers, who came under the control of the Dáil and became known as the Irish Republican Army, fought against British state forces in the Irish War of Independence.
