Halldóra Tumadóttir

Halldóra Tumadóttir (1180–1247), was a politically active Icelandic woman, spouse of Sighvatr Sturluson and sister of Kolbeinn Tumason; she became the mother of Sturla Sighvatsson. She is portrayed as a minor figure, but an important one, in the political wars and feuds on Iceland during the Age of the Sturlungs. Her marriage in 1215 was a political match which brought peace between her two families.
