Who was Ramsay Macdonald? When was Asquith? What (and why) was Bonar Law? Whenever I hear one of these names I wish I knew more about British politics of the past hundred years.
I was about to say that I don't care so much about the Nineteenth Century... but now I sense a creeping uncertainty about Gladstone, Disraeli, Palmerston, Peel and Melbourne.
Still, for my own benefit, I've just drawn up a list of Twentieth Century prime ministers.
