Overview
Christina Nilsdotter Gyllenstierna of Fogelvik (Swedish: Kristina or Kerstin: 1494 – January 1559, Hörningsholm Castle) 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 house of nobility to which she belonged.
Early life
Christina Gyllenstierna was born to riksråd Nils Eriksson (Gyllenstierna), Lord of Tullgarn (also written with the Danish spelling Niels Eriksen, and surnamed "Gyllenstjerna" by later historians) and Sigrid Eskilsdotter (Banér) of Venngarn, Heir of Lindholm. She was a great-granddaughter of King Charles VIII of Sweden through her paternal grandmother princess Christina Karlsdotter Bonde (1432-1493/1500), heir of Fogelvik, after whom she was named. Her grandfather Erik Eriksen of Demstrup ("Gyldenstjerne") originated from Denmark, but during the power struggle between Denmark and Sweden, two formally united parts of the Kalmar Union, he allied with the Swedish claimant, Charles VIII, who made him his son-in-law and High Steward of Charles' court. By the second marriage of her mother, Christina became the half-sister of Cecilia Månsdotter of Eka and thereby the maternal aunt of the future king Gustav I.
Christina was first engaged to Nils Gädda (d. 1508), governor of Kalmar and Lycka, but the marriage never took place due to his death. On 16 November 1511 in Stockholm, she married the son of the Swedish regent Svante and the nephew of her former betrothed, Sten Sture the Younger. She had five children during her marriage: Nils (1516-1528), Iliana (1514), Magdalena (1516-1521), Svante Stensson Sture (1517-1567), Anna (1518), and Gustav (1520-1520).
Reign of Sten Sture
In 1512, Sten Sture succeeded his father as elected regent of Sweden upon his death. During this period, Denmark, Norway and Sweden were formally part of the Kalmar Union through a personal union under the king of Denmark, but in reality, Sweden had been a de facto independent kingdom under "Regents" (Sw. riksföreståndare) native high nobles elected to rule the country.
