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developments in Ireland resulted in further postponements, meaning that the Act never became effective; it was finally superseded by a fourth home rule bill, enacted as the Government of Ireland Act 1920, which partitioned Ireland, creating Northern Ireland and Southern Ireland, both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.
