The Easter Rising (Irish: Éirí Amach na Cásca), also known as the Easter Rebellion, was an armed insurrection in Ireland during Easter Week in April 1916. The Rising was launched by Irish republicans against British rule in Ireland with the aim of establishing an independent Irish Republic while the United Kingdom was fighting the First World War. It was the most significant uprising in Ireland since the rebellion of 1798 and the first armed conflict of the Irish revolutionary period. Sixteen of the Rising's leaders were executed starting in May 1916. The nature of the executions, and subsequent political developments, ultimately contributed to an increase in popular support for Irish independence.
Organised by a seven-man Military Council of the Irish Republican Brotherhood, the Rising began on Easter Monday, 24 April 1916 and lasted for six days. Members of the Irish Volunteers, led by schoolmaster and Irish language activist Patrick Pearse, joined by the smaller Irish Citizen Army of James Connolly and 200 women of Cumann na mBan seized strategically important buildings in Dublin and proclaimed the Irish Republic. The British Army brought in thousands of reinforcements as well as artillery and a gunboat. There was street fighting on the routes into the city centre, where the rebels slowed the British advance and inflicted many casualties. Elsewhere in Dublin, the fighting mainly consisted of sniping and long-range gun battles. The main rebel positions were gradually surrounded and bombarded with artillery. There were isolated actions in other parts of Ireland; Volunteer leader Eoin MacNeill had issued a countermand in a bid to halt the Rising, which greatly reduced the extent of the rebel actions.
With much greater numbers and heavier weapons, the British Army suppressed the Rising. Pearse agreed to an unconditional surrender on Saturday 29 April, although sporadic fighting continued briefly. After the surrender, the country remained under martial law. About 3,500 people were taken prisoner by the British and 1,800 of them were sent to internment camps or prisons in Britain. Most of the leaders of the Rising were executed following courts martial. The Rising brought physical force republicanism back to the forefront of Irish politics, which for nearly fifty years had been dominated by constitutional nationalism. Opposition to the British reaction to the Rising contributed to changes in public opinion and the move toward independence, as shown in the 1918 general election, in which Sinn Féin won 73 of the 105 Irish seats. Sinn Féin convened the First Dáil and declared independence.
Of the 485 people killed, 260 were civilians, 143 were British military and police personnel, and 82 were Irish rebels, including 16 rebels executed for their roles in the Rising. More than 2,600 people were wounded. Many of the civilians were killed or wounded by British artillery fire or were mistaken for rebels. Others were caught in the crossfire during firefights between the British and the rebels. The shelling and resulting fires left parts of central Dublin in ruins.
The Acts of Union 1800 united the Kingdom of Great Britain and the Kingdom of Ireland as the United Kingdom of Great Britain and Ireland, abolishing the Irish Parliament and giving Ireland representation in the British Parliament. From early on, many Irish nationalists opposed the union and the continued lack of adequate political representation, along with the British government's handling of Ireland and Irish people, particularly the Great Famine. The union was closely preceded by and formed partly in response to the Irish Rebellion of 1798 – whose centenary would prove an influence on the Easter Rising. Three more rebellions ensued: one in 1803, another in 1848 and one in 1867. All were failures.
Opposition took other forms: constitutional (the Repeal Association; the Home Rule League) and social (disestablishment of the Church of Ireland; the Land League). The Irish Home Rule movement sought to achieve self-government for Ireland, within the United Kingdom. In 1886, the Irish Parliamentary Party under Charles Stewart Parnell succeeded in having the First Home Rule Bill introduced in the British parliament, but it was defeated. The Second Home Rule Bill of 1893 was passed by the House of Commons but rejected by the House of Lords.
After the death of Parnell, younger and more radical nationalists became disillusioned with parliamentary politics and turned toward more extreme forms of separatism. The Gaelic Athletic Association, the Gaelic League, and the cultural revival under W. B. Yeats and Augusta, Lady Gregory, together with the new political thinking of Arthur Griffith expressed in his newspaper Sinn Féin and organisations such as the National Council and the Sinn Féin League, led many Irish people to identify with the idea of an independent Gaelic Ireland.
The Third Home Rule Bill was introduced by British Liberal Prime Minister H. H. Asquith in 1912. Irish Unionists, who were overwhelmingly Protestants, opposed it, as they did not want to be ruled by a Catholic-dominated Irish government. Led by Sir Edward Carson and James Craig, they formed the Ulster Volunteers (UVF) in January 1913. The UVF's opposition included arming themselves, in the event that they had to resist by force.
Seeking to defend Home Rule, the Irish Volunteers was formed in November 1913. Although sporting broadly open membership and without avowed support for separatism, the executive branch of the Irish Volunteers – excluding leadership – was dominated by the Irish Republican Brotherhood (IRB) who rose to prominence via the organisation, having restarted recruitment in 1909. These members feared that Home Rule's enactment would result in a broad, seemingly perpetual, contentment with the British Empire. Another militant group, the Irish Citizen Army, was formed by trade unionists as a result of the Dublin Lock-out of that year. The issue of Home Rule appeared to some, as the basis of an "imminent civil war".
On the outbreak of the First World War, the Third Home Rule Bill was enacted, but its implementation was postponed for the war's duration. It was widely believed at the time that the war would not last more than a few months. The Irish Volunteers split: the great majority of its 160,000 members – thereafter known as the National Volunteers – followed John Redmond and supported the British war effort, some 35,000 to 40,000 of them enlisting in the British Army, while the smaller faction of 2,000 to 3,000 – who retained the name – opposed any involvement in the war. The official policy thus became "the abolition of the system of governing Ireland through Dublin Castle and the British military power and the establishment of a National Government in its place"; the Volunteers believed that "England's difficulty" was "Ireland's opportunity".
The Supreme Council of the IRB met on 5 September 1914, just over a month after the British government had declared war on Germany. At this meeting, they elected to stage an uprising before the war ended and to secure help from Germany. Responsibility for the planning of the rising was given to Tom Clarke and Seán Mac Diarmada. Patrick Pearse, Michael Joseph O'Rahilly, Joseph Plunkett and Bulmer Hobson would assume general control of the Volunteers by March 1915.
In May 1915, Clarke and Mac Diarmada established a Military Council within the IRB, consisting of Pearse, Plunkett and Éamonn Ceannt – and soon themselves – to devise plans for a rising. The Military Council functioned independently and in opposition to those who considered a possible uprising inopportune. Volunteer Chief-of-Staff Eoin MacNeill supported a rising only if the British government attempted to suppress the Volunteers or introduce conscription in Ireland, and if such a rising had some chance of success. Hobson and IRB President Denis McCullough held similar views as did much of the executive branches of both organisations.
