Who married Sten Sture the Younger?

Sten Sture the Younger (Swedish: Sten Sture den yngre) (1493 – 3 February 1520), was a Swedish nobleman who served as the regent of Sweden during the era of the Kalmar Union.

Christina Nilsdotter Gyllenstierna of Fogelvik (Swedish: Kristina or Kerstin: 1494 – January 1559) was a Swedish noblewoman. She was married to the Swedish regent Sten Sture the Younger and led the Swedish resistance against Christian II of Denmark after the death of her spouse. In her own lifetime, she was simply referred to as Fru Kristina ('Lady Christina'), but she has become known in history as Kristina Gyllenstierna because of the noble family to which she belonged.
