Peter the Great had paid a famous visit to the Prussian court, hoping to conclude an alliance with Frederick William I against Charles XII, his northern adversary. Queen Catherine and her ladies had been sharply criticized when they arrived at Berlin, and Peter's own bearing did not escape much adverse comment and secret ridicule; nevertheless he received many splendid presents, and these, no doubt, atoned to him for anything which seemed lacking in his reception.

A splendid yacht sailed toward Petersburg as the gift of Frederick, who was anxious to conciliate the uncouth ruler of the East. In return, men of gigantic stature were sent annually from Russia to enter the splendid Potsdam Guards, so dear to the monarch, who was a stern soldier and loved the martial life. Prussia was a new kingdom obtained for his descendants by the Elector of Brandenburg. It was necessary that the rulers should devote themselves to recruiting a goodly force, since their land might be easily attacked by foreign foes and divided among the greater powers, if they did not protect it well.

Frederick William sent recruiting sergeants far and wide, and suffered these even to enter churches during service and to carry off by force the stalwart young men of the congregation. Yet he was a pious man, an enemy to vice, and a ruler of enormous diligence. He rid himself of useless attendants as soon as his father died, and exercised the strictest economy in his private life. He kept the purse-strings and was also his own general. He was ever about the streets, accosting idlers roughly, and bidding the very apple-women knit at their stalls while they were awaiting custom. He preached industry everywhere, and drilled his regiments with zealous assiduity.

Of tall stature and florid complexion, the King struck terror into the hearts of the coward and miscreant. He despised extravagance in dress. French foppery was so hateful to him that he clothed the prison gaolers in Parisian style, trusting that this would bring contempt on foreign fashions.

The Potsdam Guards were under the strictest discipline, and the Prussian soldiers won battles by sheer mechanical obedience to orders when they took the field. Death punished any resistance to a superior officer, and merciless flogging was inflicted on the rank and file. Boys were often reluctant to enter on such a course of training, and parents were compelled to give up their sons by means of Dragonnades—soldiers quartered upon subjects who were not sufficiently patriotic to furnish recruits for the State. Every man of noble birth had to be an officer, and must serve until his strength was broken. The King fraternized only with soldiers because these were above other classes and belonged more or less to his own order. The army had been raised to 80,000 men when Frederick William I died, holding the fond belief that his successor had it in his power to enlarge the little kingdom which the old Elector had handed down with pride.

The Crown Prince, Frederick of Brandenburg and Hohenzollern, was born in the royal palace of Berlin on January 24th of 1712. He was christened Friedrich "rich in peace"—a name strangely ironical since he was trained from his earliest years to adopt a martial life. From the child's eighth year he was educated by military tutors, and bred in simple habits that would make him able to endure the hardships of a camp.

The martinet, Frederick William I, laid down strict rules for his son's training, for he longed to be followed by a lad of military tastes. He was to learn no Latin but to study Arithmetic, Mathematics and Artillery and to be thoroughly instructed in Economy. The fear of God was to be impressed on the pupil, and prayers and Church services played an important part in the prince's day, of which every hour had its allotted task. Haste and cleanliness were inculcated in the simple royal toilette, for Frederick I had, for those days, a quite exaggerated idea of cleanliness, but he particularly impressed upon attendants that "Prayer with washing, breakfast and the rest" were to be performed within fifteen minutes. It was a hard life, destined to bring the boy a "true love for the soldier business." He was commanded to love it and seek in it his sole glory. The father returned from war with the Swedes in January 1716, victorious, and delighted to see the little Fritz, then of the tender age of three, beating a toy drum, and his sister Wilhelmina, aged seven, in a martial attitude.

But the Crown Prince began to disappoint his father by playing the flute and reading French romances. He liked fine clothes too, and was caught wearing a richly embroidered dressing-gown, to the rage of the King, who put it in the fire. Frederick liked to arrange his hair in flowing locks instead of in a club after the military fashion. "A Querpfeifer und Poet, not a soldier," the indignant father growled, believing the Querpfeif, or Cross-Pipe, was only fit for a player in the regimental band. Augustus William, another son, ten years younger than Fritz, began to be the hope of parental ambition. He took more kindly to a Spartan life than his elder brother. There were violent scenes at court when Frederick the younger was asked to give up his right to the succession. He refused to be superseded, and had to endure much bullying and privation. The King was ever ready with his stick, and punished his son by omitting to serve him at his rather scanty table!

There was much talk of a double marriage between the English and the Prussian courts, which were then related. Frederick was to marry Amelia, daughter of George I while his sister, pretty pert Wilhelmina, was destined for Frederick, Prince of Wales. The King of Prussia set his heart on the plan, and was furious that George I did not forward it. The whole household went in fear of him; he was stricken by gout at the time, an affliction that made him particularly ill-tempered, and Wilhelmina and Fritz were the objects of his wrath. They fled from his presence together; the Prince was accused of a dissolute life, and insulted by a beating in public.
