Voting in most Irish constituencies occurred on 14 December 1918.
While the rest of the United Kingdom fought the 'Khaki election' on other issues involving the British parties, in Ireland four major political parties had national appeal.
These were the IPP, Sinn Féin, the Irish Unionist Party and the Irish Labour Party.
The Labour Party, however, decided not to participate in the election, fearing that it would be caught in the political crossfire between the IPP and Sinn Féin; it thought it better to let the people make up their minds on the issue of Home Rule versus a Republic by having a clear two-way choice between the two nationalist parties.
The Unionist Party favoured continuance of the union with Britain (along with its subordinate, the Ulster Unionist Labour Association, who fought as 'Labour Unionists').
A number of other small nationalist parties also took part.

In Ireland 105 MPs could be elected from 103 constituencies (although, as stated below, four MPs were elected for two constituencies and so the total number of people elected was 101).
Ninety-nine seats were elected from single seat geographical constituencies under the first-past-the-post voting system.
However, there were also two two-seat constituencies: University of Dublin (Trinity College) elected two MPs under the single transferable vote and Cork City elected two MPs under the bloc voting system.

In addition to ordinary geographical constituencies there were three university constituencies: the Queen's University of Belfast (which returned a Unionist), the University of Dublin (which returned two Unionists) and the National University of Ireland (which returned a member of Sinn Féin).

Of the 105 seats, 25 were uncontested, with a Sinn Féin candidate winning unopposed.
Seventeen of these seats were in Munster.
In some cases it was because there was a certain winner in Sinn Féin.
British government propaganda formulated in Dublin Castle and circulated through a censored press alleged that republican militants had threatened potential candidates to discourage non-Sinn Féiners from running.
