The aftermath of the Austro-Prussian war gave Bismarck full rein for his talents. I had never realized until I read someof the sources for today's work how much he did, in his deceptively lazy way, to shore up the benefits of Königgrätz. He may almost have done too much. The Luxemberg crisis of 1867, though, proved both how necessary his efforts were and how good he was at what he did. Wonders abound.
