Ingeborg of Norway
Ingeborg of Norway (1301–1361) was the only legitimate daughter of King Håkon V. In 1312 she married the Swedish duke Erik Magnusson. After Erik died in prison in 1318 and Håkon V in 1319, her young son Magnus inherited Norway and was elected king of Sweden, and Ingeborg participated in the regency governments, becoming Sweden's first female regent.
Her tie to Canute Porse and her independent rule led the nobility to remove her in 1326–1327. She later married Porse, duke of Halland, and died in 1361.
