Beginning from 1870 under Isaac Butt's Home Government Association, it only became a disciplined successful party under Parnell 1880–90. It split into contending factions over Parnell's fall 1890–1 and unity was only restored in 1900 under John Redmond. Appearing close to success when the third Home Rule Bill was introduced in 1912, it suffered from the effective opposition in Ulster and in the Conservative Party to that bill. By supporting the British government in the First World War, it was blamed for the war's increasing unpopularity, and was obliterated by Sinn Fein in the 1918 general election.
