Otto von Bismarck was the first Chancellor of Germany, whose unification he largely engineered.  The Schleswig-Holstein Question, a fiendishly complex matter of sovereign inheritance, led in part to the formation of the new Germany.

If Bismarck is the ‘Great Hound', the ‘Two Powers’ would be Prussia and Austria, who went to war over the duchies of Schleswig and Holstein.
