A full length portrait of Friedrich Wilhelm by an unknown hand is in the castle, Schwerin (see E. & J. Borchardt, Mecklenburgs Herzöge, p.84, ill).
Friedrich Wilhelm, son of Friedrich I, Duke of Mecklenburg-Schwerin (1638-1688) and Christine Wilhelmine, née Von Hessen-Homburg (1653-1722), married Sophie Charlotte Von Hessen-Kassel on 2 January 1704. He succeeded his father to the throne in 1692. In a subsequent war, he was besieged by his cousin Adolf Friedrich II, Duke of Mecklenburg-Güstrow until the Treaty of Hamburg in 1701. In this treaty it was confirmed, that Friedrich Wilhelm annexed Güstrow, and that Adolf Friedrich kept Stargard and Ratzeburg, and Strelitz as his residence. During his reign Friedrich Wilhelm concentrated on the finances of the city of Schwerin: he developed a new currency and he undertook the construction of a new part of the city, called Schelfstadt, and the Nikolaikirche. His marriage with Sophie Charlotte remained childless.
