The Irish component of the 1918 United Kingdom general election took place on 14 December 1918. It was the final United Kingdom general election to be held throughout Ireland, as the next election would happen following Irish independence. It is a key moment in modern Irish history, seeing 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. Sinn Féin had never previously stood in a general election, but had won six seats in by-elections in 1917–1918. The party had vowed in its manifesto to establish an independent Irish Republic. In Ulster, however, the Unionist Party was the most successful party.
The 1925 Northern Ireland general election was held on 3 April 1925. It was the second election to the Parliament of Northern Ireland. It saw significant losses for the Ulster Unionist Party, although they maintained their large majority. This was the last election for the Stormont parliament conducted using Single transferable voting, a form of Proportional Representation. Fifty-two members were elected in ten districts, which each elected between four and eight members. The Ulster Unionist government abolished proportional representation during this parliament and replaced it with the first-past-the-post system used in Great Britain.

The 1986 Northern Ireland by-elections were fifteen by-elections held on 23 January 1986, to fill vacancies in the Parliament of the United Kingdom caused by the resignation in December 1985 of all sitting Unionist Members of Parliament (MPs).
