The Irish Parliamentary Party (IPP) was an political party formed in 1882 under the leadership of Charles Stewart Parnell and others, replacing the Home Rule League. It was instrumental in laying the groundwork for Irish self-government.
Following Parnell's fall in 1891, it split into Parnellite and anti-Parnellite wings, but reunited in 1900. The Easter Rising and the British response to it radicalised Irish politics to such an extent that the IPP lost massively in the 1918 general election, and was dissolved.
