The document discusses the Home Rule movement in Ireland and the political crisis it caused in Britain between 1909-1914. It outlines that Nationalists wanted Home Rule and an Irish parliament, while Unionists in Ulster wanted to remain part of Britain. This caused tensions, with Unionists forming the Ulster Volunteer Force (UVF) of over 100,000 men to resist Home Rule. Nationalists responded by forming the Irish Volunteers. Both groups began importing arms, increasing the threat of civil war. World War 1 interrupted this by postponing Home Rule, though tensions remained high.
