In this first comprehensive study of women as economic actors in medieval Norway, Susann Anett Pedersen analyses the economic agency of unmarried heiresses, wives and widows c.1400-1550. Drawing on sources such as sales contracts and private letter correspondence, the book investigates elite women’s formal and informal roles in decision making processes and their ability to make independent economic choices. In particular, the book stresses the importance of looking beyond the legal regulation of women’s economic activities and rather analyses women’s own actions, in order to better grasp the complexity of their economic agency.
