German princess of the House of Hohenzollern and the Duchess of Württemberg by marriage. Elisabeth Friederike Sophie was considered one of the most beautiful princesses of her time. She was praised by Italian serial lover and writer Casanova as “the most beautiful princess in Germany.”
She was the daughter of Friedrich, Margrave of Brandenburg-Bayreuth by his first wife, Princess Friederike Sophie Wilhelmine of Prussia, the favourite sister of King Friedrich II the Great.
On 26 September 1748, Elisabeth Friederike Sophie married Karl Eugen, Duke of Württemberg. On 19 February 1750 Elisabeth gave birth to their only child, a daughter, Princess Friederike Wilhelmine Augusta Luisa Charlotte of Württemberg, who died on 12 March 1751 shortly after her first birthday. The absence of a male heir increased conflicts between the young couple. The ducal couple became permanently estranged in 1756, when Karl Eugene despotically arrested and illegally imprisoned Elisabeth’s friend, chamber singer Marianne Pirker.
After the death of her father in 1763, Elisabeth inherited the castle (German: Schloss) near Donndorf (now municipality Eckersdorf), which was still under construction. It had been begun by the Margrave Friedrich, but was not completed until 1765. She remodelled and furnished the Schloss to suit her taste and personality, and gave it the name of Schloss Fantaisie which it still bears today.
She died on 6 April 1780 in the Old Castle (Alten Schloss) in Bayreuth, aged 47.
