Sophie Dorothee was a very pretty child. The plan was probably already contemplated by the parents that the two should be married in due time. Soon after this Frederick William lost his mother, and with her all of a mother’s care and gentle influences. Her place was taken by a step-mother, whose peevishness and irritability soon developed into maniacal insanity. When Frederick William was eighteen years of age he was allowed to choose between three princesses for his wife. He took his pretty cousin, Sophie Dorothee. They were married with great pomp on the 28th of November, 1706. A son was born and died. A daughter came, Wilhelmina. But a daughter could not inherit the crown. Another son was born and died. There was great anxiety at court, from fear that the direct line of succession might not be preserved. But on the 24th of January, 1712, when the monarchy was but twelve years old, the little prince was born who subsequently obtained such renown as Frederick the Great. The king, his grandfather, was aged and infirm. The excessive joy with which he greeted little Fritz, as he fondly called the child, was cordially reciprocated throughout the Prussian nation. The realm blazed with bonfires and illuminations, and resounded with every demonstration of public joy. The young prince was christened with great pomp, Charles Frederick. The emperor, Charles VI., was present on the occasion, and in the solemnities there were blended the most imposing civil, military, and ecclesiastical rites. The baptism took place on the 31st of January, 1712, when the babe was a week old. The young prince subsequently dropped the name of Charles, and Frederick became his sole designation. Wilhelmina, Frederick’s sister, was about three years older than himself. We shall have frequent occasion to allude to her in the course of this history, as between her and her brother there sprang up a warm attachment, which was of life-long continuance. Ten children were subsequently born to the royal pair, making fourteen in all, most of whom attained mature years. Frederick William, the Crown Prince, was at the time of the birth of his son Frederick twenty-four years of age. He was a very peculiar man, sturdy and thick-set in figure, of strong mental powers, but quite uneducated. He was unpolished in manners, rude in his address, honest and sincere, a stern, persevering worker, despising all luxurious indulgence, and excessively devoted to the routine of military duties.
