This category is for Members of Parliament elected for the Irish Parliamentary Party from 1882 to 1918. The constituency organisation which supported IPP candidates was initially the Irish National League, and later the United Irish League. In 1890 the Party split into Parnellite and Anti-Parnellite factions when the party leader, Charles Stewart Parnell, was named in a divorce action. The party reunited in 1900 under the leadership of John Redmond.
