Duchess of Prussia


The Queen of Prussia was the queen consort of the ruler of the Kingdom of Prussia, from its establishment in 1701 to its abolition in 1918. As all rulers of Prussia had to be male, there was never a Queen regnant of Prussia. Until 1806, the Queen of Prussia was also Electress of Brandenburg; after 1871, she was also German Empress. Until 1772, her title was Queen in Prussia (see King in Prussia).
