Home Rule seemed certain when the Parliament Act 1911 abolished the veto of the House of Lords, and John Redmond secured the Third Home Rule Act in 1914. However, the Unionist movement had been growing since 1886 among Irish Protestants after the introduction of the first home rule bill, fearing discrimination and loss of economic and social privileges if Irish Catholics achieved real political power. In the late 19th and early 20th-century unionism was particularly strong in parts of Ulster, where industrialisation was more common in contrast to the more agrarian rest of the island, and where the Protestant population was more prominent, with a majority in four counties. Under the leadership of the Dublin-born Sir Edward Carson of the Irish Unionist Party and the Ulsterman Sir James Craig of the Ulster Unionist Party, unionists became strongly militant in order to oppose "the Coercion of Ulster". After the Home Rule Bill passed parliament in May 1914, to avoid rebellion with Ulster, the British Prime Minister H. H. Asquith introduced an Amending Bill reluctantly conceded to by the Irish Party leadership. This provided for the temporary exclusion of Ulster from the workings of the bill for a trial period of six years, with an as yet undecided new set of measures to be introduced for the area to be temporarily excluded.
