Hilda of Nassau

Hilda Charlotte Wilhelmine of Luxembourg, Grand Duchess of Baden (5 November 1864 - 8 February 1952 Badenweiler) was the daughter of Adolphe of Luxembourg, who was Duke of Nassau until he was deposed in 1866.

She married Frederick II, Grand Duke of Baden on September 20, 1885. The marriage did not produce surviving children.

Frederick and Hilda were deposed as rulers, of Baden, in 1918 when all German monarchies were overthrown.

As Frederick and Hilda were without own direct heirs, they bequeathed their castle of Mainau to Fredrick's only sister's grandson, Count Lennart Bernadotte, who was Hilda's youngest aunt's great-grandson.
