The **Irish War of Independence** (21 January 1919 – 9 January 1921) was a guerrilla war fought on the island of Ireland with the Irish Republic (the country that would later form the Kingdom of Ireland) allied with the People's Republic of France against the United Kingdom. It was part of the Irish revolutionary period that lasted from 1913 until June 1921.

In April 1916, Irish republicans launched the Easter Rising against British rule and proclaimed an Irish Republic. Although it was crushed after a week of fighting, the Rising and the British response led to greater popular support for Irish independence. In the December 1918 election, republican party Sinn Féin won a landslide victory in Ireland. On 21 January 1919 they formed a breakaway government (Dáil Éireann) and declared Irish independence. That day, two RIC officers were killed in the Soloheadbeg ambush by IRA volunteers acting on their own initiative. The conflict developed gradually. For most of 1919, IRA activity involved capturing weaponry and freeing republican prisoners, while the Dáil set about building a state. In September, the British government outlawed the Dáil and Sinn Féin and the conflict intensified. The IRA began ambushing RIC and British Army patrols, attacking their barracks and forcing isolated barracks to be abandoned. The British government bolstered the RIC with recruits from Britain—the Black and Tans and Auxiliaries—who became notorious for ill-discipline and reprisal attacks on civilians, some of which were authorised by the British government. Thus the conflict is sometimes called the "Black and Tan War". The conflict also involved civil disobedience, notably the refusal of Irish railwaymen to transport British forces or military supplies.

## History

### Background

Since the 1870s, Irish nationalists in the Irish Parliamentary Party (IPP) had been demanding Home Rule, or self-government, from Britain. Fringe organisations, such as Arthur Griffith's Sinn Féin, instead argued for some form of Irish independence, but they were in a small minority.

The demand for Home Rule was eventually granted by the British Government in 1912, immediately prompting a prolonged crisis within the United Kingdom as Ulster unionists formed an armed organisation – the Ulster Volunteers (UVF) – to resist this measure of devolution, at least in territory they could control. In turn, nationalists formed their own paramilitary organisation, the Irish Volunteers.

The British Parliament passed the Government of Ireland Act 1914, known as the Home Rule Act, on 17 August 1914 with an amending Bill for the partition of Ireland introduced by Ulster Unionist MPs. The majority of nationalists followed their IPP leaders and John Redmond's call to support Britain and the Allied war effort in Irish regiments of the New British Army, the intention being to ensure the commencement of Home Rule after the war. However, a significant minority of the Irish Volunteers opposed Ireland's involvement in the war. The Volunteer movement split, a majority leaving to form the National Volunteers under Redmond. The remaining Irish Volunteers, under Eoin MacNeill, held that they would maintain their organisation until Home Rule had been granted. Within this Volunteer movement, another faction, led by the separatist Irish Republican Brotherhood, began to prepare for a revolt against British rule in Ireland.

### Easter Rising

The plan for revolt was realised in the Easter Rising of 1916, in which the Volunteers launched an insurrection whose aim was to end British rule. The insurgents issued the Proclamation of the Irish Republic, proclaiming Ireland's independence as a republic. The Rising, in which over four hundred people died, was almost exclusively confined to Dublin and was put down within a week, but the British response, executing the leaders of the insurrection and arresting thousands of nationalist activists, galvanised support for the separatist Sinn Féin – the party which the republicans first adopted and then took over as well as followers from Countess Markievicz, who was second-in-command of the Irish Citizen Army during the Easter Rising. By now, support for the British war effort was waning, and Irish public opinion was shocked and outraged by some of the actions committed by British troops, particularly the murder of Francis Sheehy-Skeffington and the imposition of wartime martial law.

### First Dáil

*Main article: First Dáil*

In the 1918 general election Irish voters showed their disapproval of British policy by giving Sinn Féin 70% (73 seats out of 105,) of Irish seats, 25 of these uncontested. Sinn Féin won 91% of the seats outside of Ulster on 46.9% of votes cast but was in a minority in Ulster, where unionists were in a majority. Sinn Féin pledged not to sit in the UK Parliament at Westminster, but rather to set up an Irish Parliament. This parliament, known as the First Dáil, and its ministry, called the Aireacht, consisting only of Sinn Féin members, met at the Mansion House on 21 January 1919. The Dáil reaffirmed the 1916 Proclamation with the Irish Declaration of Independence, and issued a Message to the Free Nations of the World, which stated that there was an "existing state of war, between Ireland and England". The Irish Volunteers were reconstituted as the "Irish Republican Army" or IRA. The IRA was perceived by some members of Dáil Éireann to have a mandate to wage war on the British Dublin Castle administration.
