She was the daughter of Duke Ulrich III of Mecklenburg-Güstrow and Princess Elizabeth of Denmark (a daughter of Frederick I and Sophie of Pomerania).[1][2] Sophie married her cousin, Frederick II of Denmark, when she was 14.[1] He was 37.[1] The marriage was arranged by the Danish Council, who wished the King to marry. Though their ages were very different, their marriage was usually quiet and even happy.[1] Queen Sophie was a loving mother, nursing her children herself when they were ill. Because her husband drank lots of wine and led an unfaithful life, she sent her three oldest children to live with her parents in Güstrow when they were young. She showed a great interest in science and visited the astronomerTycho Brahe. She was also interested in the old songs of folklore. Her daughter, Anne of Denmark, would marry James VI of Scotland and become Queen Consort in 1589. She arranged the marriage against the will of the Council.
She died on 4 October 1631 at Nykøbing, Jylland, Denmark.[2]
