Margravine Philippine of Brandenburg-Schwedt

Friederike was described as witty and charming. She belonged to the reformed faith, while her consort was Catholic, but she brought up her children as Lutheran upon agreement with the Lutheran council, from whom she received an allowance.

From 1769 she lived at Montbéliard, which was being managed by her husband, but which had to be abandoned in 1792 because of the French Revolution. Her husband inherited the Dukedom of Württemberg in 1795–97.

Friederike was a daughter of Margrave Frederick William of Brandenburg-Schwedt and his wife Princess Sophia Dorothea of Prussia. Her mother was a sister of Frederick the Great.
