Frederick William was known as a brutal man because of his short temper, severity, and coarse manners. He was born at Oranienbaum Castle (modern-day
Oranienbaum-Wörlitz,
Wittenberg), and was educated and raised by his uncle, King Frederick I, and then by his cousin, King
Frederick William I. His character closely resembled that of his second royal guardian, who like himself, hated idleness and was a terror to all loungers. The clergy were especial objects of his ridicule and persecution. His cane was as much feared as that of his royal namesake. He made the fashionable
Grand Tour, travelling to
Geneva 1715, and in 1716 to Italy. He returned in 1719 to Prussia, where he received the Order of the Black Eagle from Frederick William I. On 15 June 1723 he was made a Prussian
major-general. On 10 July 1737 he was appointed
lieutenant-general. The existence of the Schwedt branch of the Hohenzollern dynasty, descended as they were from Frederick I's father and being 'princes of the blood', posed a theoretical threat to the Prussian kings. Frederick William I tried to neutralise this threat by keeping his cousins close, bringing the Schwedt brothers into his own household, acting as their guardian, and later marrying Frederick William to his daughter. Following the margrave's reaching adulthood the king was so fearful of any covert political activity on his cousin's part that he sent spies to Schwedt to find out who met with Frederick William and his brother. ==Issue==
