The Ulster Covenant is signed by some 500,000 Ulster Protestant Unionists in opposition to the Third Irish Home Rule Bill.
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 during a 28-year period in response to agitation for Irish Home Rule.
The Act was the first law ever approved by the Parliament of the United Kingdom that provided for a devolved government in any part of the UK proper (as opposed to colonial territories). However, the implementation of both it and the equally controversial Welsh Church Act 1914 was formally postponed for a minimum of twelve months with the beginning of the First World War. The continuation of the war beyond 1915 and subsequent developments in Ireland resulted in further postponements, meaning that the Act never became effective; it was finally superseded by a fourth home rule bill, enacted as the Government of Ireland Act 1920, which partitioned Ireland, creating Northern Ireland and Southern Ireland, both intended to have Home Rule.
Ulster's Solemn League and Covenant, commonly known as the Ulster Covenant, was signed by nearly 500,000 people on and before 28 September 1912, in protest against the Third Home Rule Bill introduced by the British Government in the same year.
