Count and adventurer. He was the last of a Swedish branch of a German noble dynasty. Grandson of Swedish Field Marshal Hans Christoff von Königsmarck and brother of Aurora von Königsmarck, he is most known for his love affair with Sophie Dorothea of Celle, the wife of Elector Georg Ludwig, who later became George I. of England. In 1681 he visited with his mother the court of Celle for a few weeks where he met Sophie Dorothea the first time. A few years later he met the future Friedrich August I of Saxony in Venice and went with him to Dresden to live at the court there. In 1688 he returned to Hanover, where he fell in love with Sophie Dorothea. The affair lasted nearly six years. They planed to flee from Hanover to live in Dresden under the protection of Friedrich August. During the night of July 1, 1694 Königsmarck entered the palace and was never seen again. Aurora and Friedrich August tried to find out what happened that night but were unsuccessful. Philipp Christoph either died that night or some time later in prison. According to some information Duke Anton Ulrich of Brunswick-Wolfenbüttel gathered, Königsmarks body may have been sunk in the Leine River in a sack weighted with stones. Sophie Dorothea was divorced from Georg Ludwig later that year and was banished to live at the Castle of Ahlden for the rest of her live.
