The Government of Ireland Bill 1886, commonly known as the First Home Rule Bill, was the first major attempt made by a British government to enact a law creating home rule for part of the United Kingdom of Great Britain and Ireland.
 It was introduced in 8 April 1886 by Liberal Prime Minister William Gladstone to create a devolved assembly for Ireland which would govern Ireland in specified areas.
 The Irish Parliamentary Party under Charles Stewart Parnell had been campaigning for home rule for Ireland since the 1870s.
The Government of Ireland Act 1920 (10 & 11 Geo.
 5 c. 67) was an Act of the Parliament of the United Kingdom.
 The Act's long title was "An Act to provide for the better government of Ireland"; it is also known as the Fourth Home Rule Bill or (less accurately) as the Fourth Home Rule Act.
The Home Rule Crisis was a political and military crisis in the United Kingdom of Great Britain and Ireland that followed the introduction of the Third Home Rule Bill in the House of Commons of the United Kingdom in 1912.
 Ulster unionists, determined to prevent any measure of home rule for Ireland, formed a paramilitary force, the Ulster Volunteers, which threatened to resist by physical force the implementation of the Act and the authority of any Dublin Parliament by force of arms.
 Irish nationalists responded by setting up the Irish Volunteers "to secure the rights and liberties common to all the people of Ireland".
 Both sides then began importing weapons and ammunition from Germany, in the Larne gun-running and Howth gun-running incidents.
 HM Government's ability to face down unionist defiance was thrown into question by the "Curragh incident", when dozens of British Army officers tendered their resignation rather than secure arms against Ulster loyalist seizure, forcing a climb-down by the government.
 The crisis was temporarily averted by the outbreak of World War I.
 The Home Rule Bill was enacted, but its implementation was suspended for the duration of the war.
The Council of Ireland (Irish: "Comhairle na hÉireann" ) was a statutory body established under the Government of Ireland Act 1920 as an all-Ireland law-making authority with limited jurisdiction, initially over both Northern Ireland and Southern Ireland, and later solely over Northern Ireland.
 It had 41 members: 13 members of each of the Houses of Commons of Southern Ireland and of Northern Ireland; 7 members of each of the Senates of Southern Ireland and of Northern Ireland; and a President chosen by the Lord-Lieutenant of Ireland.
 It was abolished in 1925.
The Government of Ireland Bill 1893 (known generally as the Second Home Rule Bill) was the second attempt made by William Ewart Gladstone, as Prime Minister of the United Kingdom, to enact a system of home rule for Ireland.
 Unlike the first attempt, which was defeated in the House of Commons, the second Bill was passed by the Commons only to be vetoed by the House of Lords.
Ulster's Solemn League and Covenant, commonly known as the Ulster Covenant, was signed by just under half a million Irishmen and women, mainly from Ulster, on and before 28 September 1912, in protest against the Third Home Rule Bill introduced by the British Government in the same year.
 Sir Edward Carson was the first person to sign the Covenant at Belfast City Hall with a silver pen, followed by Lord Londonderry (the former viceroy of Ireland), representatives of the Protestant churches, and then by Sir James Craig.
 The signatories, 471,414 in all, were all against the establishment of a Home Rule parliament in Dublin.
 The Ulster Covenant is immortalised in Rudyard Kipling's poem "".
 On 23 September 1912, the Ulster Unionist Council voted in favour of resolution pledging itself to the Covenant.
The Government of Ireland Act 1914 (4 & 5 Geo.
 5 c. 90), also known as the Home Rule Act, and before enactment as the Third Home Rule Bill, was an Act passed by the Parliament of the United Kingdom intended to provide home rule (self-government within the United Kingdom) for Ireland.
 It was the third such bill introduced by a Liberal government in a 28-year period in response to the Irish Home Rule movement.
"Rome Rule" was a term used by Irish unionists to describe their belief that with the passage of a Home Rule Bill, the Roman Catholic Church would gain political power over their interests in Ireland.
 The slogan was coined by the Radical MP and Quaker John Bright during the first Home Rule crisis in the late 19th century and continued to be used in the early 20th century.
The Parliament of Southern Ireland was a Home Rule legislature set up by the British Government during the Irish War of Independence under the Fourth Home Rule Bill.
 It was designed to legislate for Southern Ireland, a political entity which was created by the British Government to solve the issue of rising Irish nationalism and the issue of partitionism, whilst retaining Ireland as part of the United Kingdom.
Irish Protestant Home Rule Association was founded in Belfast in the Castle Restaurant in Donegall Place on 21 May 1886 to support Gladstones Home Rule bill for Ireland among members of the various Protestant faiths, following a defeat in the House of Commons.
