George Dangerfield's The Strange Death of Liberal England is the classic account of the many-sided political crisis that threatened to overtake the British political system in the years leading up to the First World War. This encompassed industrial unrest and the rise of the Labour Party, interacting with the Suffragette movement and its overlapping demand for expansion of the franchise, and most fatefully, the Irish Party's demand for Home Rule, opposed by a new and militant Ulster unionism backed by the Conservative Party from their powerbase in the House of Lords.
