In 1324/1325 she was accused and convicted for exercising witchcraft. She was sentenced to strict fasting and a seven year long pilgrimage to holy places outside of Norway. The trial against Ragnhild TregagÃ¥s is the only one concerning witchcraft that is known from medieval Norway, taking place 250 years before the witch-hunt in Norway started.Witchcraft, in various historical, anthropological, religious and mythological contexts, is the alleged use of supernatural or magical powers. Witchcraft often refers to the alleged use of supernatural or magical powers in order to inflict harm or damage upon members of a community or their property. Other uses of the term distinguish between bad witchcraft and good witchcraft, with the latter often involving healing, perhaps remedying bad witchcraft. The concept of witchcraft is normally treated as a cultural ideology, a means of explaining human misfortune by blaming it either on a supernatural entity or a known person in the community. A witch (from Old English wicce f. / wicca m.) is a practitioner of witchcraft.
