The Peace of Westphalia, 1648, marks the end of the Thirty Years' War, and finds Germany with a population reduced from sixteen millions to four millions. Famine which drove men and women to cannibalism, bands of them being caught cooking human bodies in a caldron for food; slaughter that drove men to make laws authorizing every man to have two wives, and punishing men and women who became monks and nuns; lawlessness that bred roving bands of murderers, who killed, robbed, and even ate their victims, demanded a ruler of no little vigor to lead his people back to civic, moral, and material health. The Great Elector wrested east Prussia from Poland, he defeated and drove off the Swedes, whom Louis XIV had drawn into an alliance against him, he travelled from end to end of his country, seeking out the problems of distress and remedying them by inducing immigration from Holland, Switzerland, and the north, by building roads, bridges, schools, and churches, and by encouraging planting, trade, and commerce. He built the Frederick William Canal connecting the Oder and the Spree, and introduced the potato to his countrymen. Germany now produces in normal years fifteen hundred million bushels of potatoes. The splendid equestrian statue of the Great Elector on the long bridge at Berlin, is a worthy monument to the first great Hohenzollern.
When Charles II of Spain died, Louis XIV, the Emperor Leopold I of the Holy Roman Empire, and the Elector of Bavaria, all three claimed the right to name his successor. In the war that followed and which lasted a dozen years, the Emperor, Holland, England, Portugal, the Elector of Hanover, and the Elector Frederick III of Brandenburg, the son of the Great Elector, were allied against France. Frederick, the Elector of Brandenburg, was permitted by the Emperor, in return for his services at this time, to assume the title of King, and he crowned himself and his wife Sophia Elizabeth, at Königsberg, King and Queen of Prussia, taking the title of Frederick I of Prussia, January 18th, 1701.
This novus homo among sovereigns was now a fellow king with the rulers of England, France, Denmark, and Sweden, and the only crowned head in the empire, except the Emperor himself, and the Elector of Saxony, who had been chosen King of Poland in 1697. By persistent sycophancy he had pushed his way into the inner circle of the crowned. Those who have picked social locks these latter days by similar sycophancies, by losses at bridge in the proper quarter, by suffering sly familiarities to their women folk, and by wearing their personal and family dignity in sole leather, may know something of the humiliating experiences of this new monarch. He was a feeble fellow, but his son and successor, Frederick William I, "a shrewd but brutal boor," so Lord Rosebery calls him, and there could not be a better judge, amazed Europe by his taste for collecting tall soldiers, by his parsimony, his kennel manners in the treatment of his family and his subjects, and leaves a name in history as the first, greatest, and the unique collector of human beings on a Barnumesque scale. All known collectors of birds, beetles, butterflies, and beasts accord him an easy supremacy, for his aggregation of colossal grenadiers.
