Sinn Féin, pledged to an Irish Republic, wins 73 of 105 Irish Member of Parliament (MP) seats in the 1918 Irish general election held on December 14, 1918. Winners include Constance Markievicz who becomes the first woman elected to the Parliament of the United Kingdom. In 1919 she is appointed Minister for Labour, the first female minister in a democratic government cabinet.
The Irish general election is that part of the 1918 United Kingdom general election which takes place in Ireland. The election is now seen as a key moment in modern Irish history because it sees the overwhelming defeat of the moderate nationalist Irish Parliamentary Party (IPP), which had dominated the Irish political landscape since the 1880s, and a landslide victory for the radical Sinn Féin party. The party had never stood in a general election, but had won six seats in by-elections in 1917–1918. Sinn Féin vows in its manifesto to establish an independent Irish Republic. In Ulster, however, the Unionist Party is the most successful party.
The election is held in the aftermath of World War I, the Easter Rising and the Conscription Crisis. It is the first general election to be held after the Representation of the People Act 1918. It is thus the first election in which women over the age of 30, and all men over the age of 21, can vote. Previously, all women and most working-class men had been excluded from voting.
In the aftermath of the elections, Sinn Féin’s elected members refuse to attend the British Parliament in Westminster. Instead they form a parliament in Dublin, the First Dáil Éireann, which declares Irish independence as a republic. The Irish War of Independence is conducted under this revolutionary government which seeks international recognition, and sets about the process of state-building.
