The Home Rule movement (Irish: Rialtas Dúchais) was a movement that campaigned for self-government (or "home rule") for Ireland within the United Kingdom of Great Britain and Ireland. It was the dominant political movement of Irish nationalism from 1870 to the end of World War I.
Isaac Butt founded the Home Government Association in 1870. This was succeeded in 1873 by the Home Rule League, and in 1882 by the Irish Parliamentary Party. These organisations campaigned for home rule. The House of Commons of the United Kingdom introduced the First Home Rule Bill in 1886, but the bill was defeated in the House of Commons after a split in the Liberal Party. After Parnell's death, Gladstone introduced the Second Home Rule Bill in 1893; it passed the Commons but was defeated in the House of Lords. After the removal of the Lords' veto in 1911, the Third Home Rule Bill was introduced in 1912, leading to the Home Rule Crisis. Shortly after the outbreak of World War I it was enacted, but implementation was suspended until the conclusion of the war.
