Not exactly, the Irish had constituencies represented in the British Parliament since the Act of Union between Great Britain and Ireland in 1800, the number of seats located in Ireland usually numbered in the range of 100-105 MPs. For example, in 1906 the Irish Nationalists who called for 'Home Rule' in Ireland won 82 seats. However, what should be remembered is that between 1885-1918 the electorate of Great Britain and Ireland was around 60% of the adult male population, so in that way there was some form of 'Taxation without Representation'.

The main reason for the Irish revolt was generally the aftermath of the 1916 Easter Rising, where members of the then small group Sinn Fein stormed the General Post Office in Dublin and attempted to establish an independent Ireland as the Third Irish Home Rule Bill was suspended in 1914 due to the outbreak of World War I. The rebels were summarily executed by the British Government which sparked an outcry among the Irish public leading to the illegal (to the British Government) formation of an Irish Parliament when Sinn Fein won 73 seats in 1918 which lead to the Irish War of Independence.
