When Friedrich von Raumer was in England, in 1835, he, at an English dinner, gave this toast: "The King of Prussia, the greatest and best reformer in Europe." That he was the "best reformer in Europe," we will not insist upon,--but that he was the greatest reformer there, we have no doubt whatever. That he was a reformer at heart, originally, no one would pretend who knows his history. He was made one by stress of circumstances. But having become a reformer, he did a great work, as contemporary history shows. He would have been content to live, and reign, and die, sovereign of just such a Prussia as he found in 1797; but, in spite of himself, he was made to effect a mightier revolution than even a French revolutionist of 1793 would have deemed it possible to accomplish. His career is the liveliest illustration that we know of the doctrine that men are the sport of circumstances. Frederick William III. died in 1840. His son and successor, Frederick William IV., was a man of considerable ability and a rare scholar; but he was not up to his work, the more so that the age of revolutions appeared again early in his reign. He might have made himself master of all Germany in 1848, but had not the courage to act as a Prussian sovereign should have acted. He was elected Emperor by the revolutionary Diet at Frankfort, but refused the crown. A little later, under the inspiration of General Radowitz, he took up such a position as we have seen his successor fill so effectively. War with Austria seemed close at hand, and the unity of Germany might have been brought about sixteen years since had the Prussian monarch been equal to the crisis. As it was, he "backed down," and Radowitz, who was a too-early Bismark, left his place, and died at the close of 1853. The king lost his mind in 1857; and his brother William became Regent, and succeeded to the throne in 1861, on the death of Frederick William IV.
