Based on legislation and legal practice from the period c. 1250-1600 the book takes issue with the most important viewpoints in earlier research by early modernists: that the Reformation represented a watershed in a development characterized by greater criminalisation of sexual acts, increase in the severity of sentences and deterioration of the position of women. According to this study, in principle all or mostly all factors were already in place in the Middle Ages. In Norwegian historiography the period investigated is characterized by paucity of sources, and the period has tended to fall between two stools, respectively the medievalist and the early modernist. The ambition of this book has been to bridge the gap.
