William I of Prussia

The outcome of the war increased the prestige of Prussia. She had armed, not with the idea of going to the aid of a German power in difficulties, but in order, at the right moment, to cast her sword into the scale wherein her own interests might for the time lie. At the menace of her armaments, concentrated on the Rhine, Napoleon had stopped dead in the full career of victory; Austria, in the eyes of German men, had been placed under an obligation to her rival; and Italy realized the emergence of a new military power, whose interests in antagonism to Austria were identical with her own.

No one who looked at the state of European politics in 1861, could have imagined that in less than ten years Prussia would have waged three wars and humbled the might of Austria and France. At that time she showed no signs of exceptional vigour: she had as yet produced no leaders so inspiring as Mazzini and Garibaldi, no statesman so able as Cavour. Her new king, William, far from arousing the feelings of growing enthusiasm that centred in Victor Emmanuel, was more and more distrusted and disliked by Liberals for the policy of militarism on which he had just embarked.

For Frederick William the position of leader of Germany now meant the employment of the military force of Prussia to crush the scattered elements of revolution that survived the collapse of the national movement. His establishment of the northern confederacy was a reversion to the traditional policy of Prussia in opposition to Austria, which, after the emperor Nicholas had crushed the insurrection in Hungary, was once more free to assert her claims to dominance in Germany.
