Mette Iversdatter was born at
Tirsbæk in
Jutland in
Denmark. She was the daughter of the Danish
knight Iver Jenssen Dyre (d. ca. 1463) and Kristine Pedersdatter Oxe (d. after 1503). In ca. 1483, she married the Norwegian knight and
riksråd Anders van Bergen (d. 1491). With her first spouse, she had her only child to reach adulthood, her daughter Christina Andersdatter. In 1496, she married secondly to the Norwegian-Swedish noble
Knut Alvsson Tre Rosor (d. 1502), who was a Norwegian
riksråd and the fiefholder of
Akershus Fortress in
Oslo. In 1499, Knut Alfsson lost his position in Norway, and she followed him to Sweden. In Sweden, the couple allied themselves with
Svante Sture: he was at that time not yet Regent of Sweden, but a leading member of the Swedish party who wished to dissolve the union between Sweden and
Denmark-Norway. In 1501, supported by Sture, Knut Alfsson
invaded Norway in an attempt to unite Sweden and Norway against
King Hans. Mette remained in Sweden at Svante's fiefdom
Stegeborg Castle. Initially successful, Knut Alfsson was murdered by
Henrik Krummedige during a
parley. In collaboration with Svante Sture, Mette continued the work of her late spouse, and maintained negotiations with Norwegian representatives through correspondence from her base in Sweden in an attempt to convince them to ally Norway with Sweden against Denmark. King Hans of Denmark accused her of having sent out letters to encourage the Norwegian peasantry to rebel against him. == Regent consort ==
