context_page_description: The first evidence of human presence in Ireland may date to about 12,500 years ago. The receding of the ice after the Younger Dryas cold phase of the Quaternary around 9700 BC, heralds the beginning of Prehistoric Ireland, which includes the archaeological periods known as the Mesolithic, the Neolithic from about 4000 BC, the Copper and Bronze Age from about 2300 BC and Iron Age beginning about 600 BC. Ireland's bronze age begins with the emergence of "protohistoric" Gaelic Ireland in the 2nd Millennium BC and ends with arrival of Celtic la Tène culture by central Europe
  By the late 4th century AD Christianity had begun to gradually subsume or replace the earlier Celtic polytheism. By the end of the 6th century it had introduced writing along with a predominantly monastic Celtic Christian church, profoundly altering Irish society. Viking raids and settlement from the late 8th century AD resulted in extensive cultural interchange, as well as innovation in military and transport technology. Many of Ireland's towns were founded at this time as Viking trading posts and coinage made its first appearance.
context_section_description: Home Rule became certain when in 1910 the Irish Parliamentary Party (IPP) under John Redmond held the balance of power in Commons and the third Home Rule Bill was introduced in 1912. Unionist resistance was immediate with the formation of the Ulster Volunteers. In turn the Irish Volunteers were established to oppose them and enforce the introduction of self-government.
  In September 1914, just as the First World War broke out, the UK Parliament passed the Government of Ireland Act 1914 to establish self-government for Ireland, but it was suspended for the duration of the war. To ensure implementation of Home Rule after the war, nationalist leaders and the IPP under Redmond supported with Ireland's participation in the British and Allied war effort under the Triple Entente against the expansion of Central Powers. The core of the Irish Volunteers were against this decision, but the majority left to form the National Volunteers who enlisted in Irish regiments of the New British Army, the 10th and 16th (Irish) Divisions, their Northern counterparts in the 36th (Ulster) Division. Before the war ended, Britain made two concerted efforts to implement Home Rule, one in May 1916 and again with the Irish Convention during 1917–1918, but the Irish sides (Nationalist, Unionist) were unable to agree to terms for the temporary or permanent exclusion of Ulster from its provisions.
  The period 1916–1921 was marked by political violence and upheaval, ending in the partition of Ireland and independence for 26 of its 32 counties. A failed militant attempt was made to gain separate independence for Ireland with the 1916 Easter Rising, an insurrection in Dublin. Though support for the insurgents was small, the violence used in its suppression led to a swing in support of the rebels. In addition, the unprecedented threat of Irishmen being conscripted to the British Army in 1918 (for service on the Western Front as a result of the German Spring Offensive) accelerated this change. In the December 1918 elections Sinn Féin, the party of the rebels, won three-quarters of all seats in Ireland, twenty-seven MPs of which assembled in Dublin on 21 January 1919 to form a 32-county Irish Republic Parliament, the first Dáil Éireann unilaterally declaring sovereignty over the entire island.
  Unwilling to negotiate any understanding with Britain short of complete independence, the Irish Republican Army, the army of the newly declared Irish Republic, waged a guerilla war (the Irish War of Independence) from 1919 to 1921. In the course of the fighting and amid much acrimony, the Fourth Government of Ireland Act 1920 implemented Home Rule while separating the island into what the British government's Act termed "Northern Ireland" and "Southern Ireland". In July 1921 the Irish and British governments agreed to a truce that halted the war. In December 1921 representatives of both governments signed an Anglo-Irish Treaty. The Irish delegation was led by Arthur Griffith and Michael Collins. This abolished the Irish Republic and created the Irish Free State, a self-governing Dominion of the Commonwealth of Nations in the manner of Canada and Australia. Under the Treaty, Northern Ireland could opt out of the Free State and stay within the United Kingdom: it promptly did so. In 1922 both parliaments ratified the Treaty, formalising independence for the 26-county Irish Free State (which renamed itself Ireland in 1937, and declared itself a republic in 1949); while the 6-county Northern Ireland, gaining Home Rule for itself, remained part of the United Kingdom. For most of the next 75 years, each territory was strongly aligned to either Catholic or Protestant ideologies, although this was more marked in the six counties of Northern Ireland.
