Results of the 1910 election in Ireland. Cork City was a two-seat constituency, in this case both seats were won by the All-for Ireland League.
The Irish component of the December 1910 UK general election took place between 3 and 19 December, concurrently with the polls in Great Britain. Though the national result was a deadlock between the Conservatives and the Liberals, the result in Ireland was, as was the trend by now, a large victory for the Irish Parliamentary Party. The IPP supported the Liberals to form a government after the election. This was to be the party's last victory, however. Due to the outbreak of World War I in 1914, the next general election would not be held until 1918, by which time events both in Ireland and Britain and outside would conspire to see the rise of a new nationalist party, Sinn Féin, and the subsequent demise of the IPP.
It was the government formed by this election which brought in the final, fourth Home Rule bill in 1914. The outbreak of the war led to its delay and eventual abandonment in response to the rise of Sinn Féin.
The war caused an unprecedented eight-year gap between this election and the next one. As a result, a large number of by-elections were held over the parliament's term. 1917 saw the first electoral victory for a new nationalist party, Sinn Féin, which won its first seat in the Roscommon North by-election of February 1917. The party would gain more seats in further by-elections, precipitating its landslide victory over the I.P.P. in the 1918 general election. Among the Sinn Féin MPs elected during this time were future Taoiseach and President of IrelandÉamon de Valera and future President of the Executive CouncilW. T. Cosgrave. Sinn Féin's cause was not Home rule but rather complete independence for an Irish Republic. The party and its members had been heavily involved in the Easter Rising of 1916, in which an unofficial republic had been declared. Its elected MPs operated by a policy of abstentionism from Westminster. Sinn Féin would use its success in the next election to form its own extra-legal parliament, Dáil Éireann in Dublin.
