I have heard it said on this website that WWI greatly diminished the power of the British aristocracy as their heirs died in battle and many went bankrupt funding the war. How true is this? If it is true, what would British aristocracy and the political landscape look like in the absence of WWI or in the absence of British participation in the war? What would this mean for government and everyday life in Britain? Would the House of Lords be more powerful? What effects, if any, would it have of the Empire/Commonwealth?
