Sophia Dorothea of Celle

Sophia Dorothea (15 September 1666 – 13 November 1726) was the wife and cousin of George Louis, Elector of Hanover, later George I of Great Britain, and mother of George II through an arranged marriage of state, instigated by the machinations of Duchess Sophia of Hanover. She is best remembered for her affair with Philip Christoph von Königsmarck that led to her being imprisoned in Castle of Ahlden for the last thirty years of her life. Although from 1714 she became Queen Consort of Great Britain she was never to visit that country because of her imprisonment.
