Heather Marsh has tied the persecution of witches to the fight of church and industry to control "the power of life and death" at a time when industry needed more workers. She also argues the persecution of witches was a fight for centralized power over the peasant rebellions and the ownership of knowledge by medicine and science which forbade the earlier teaching or practices by women and indigenous cultures. She writes that the persecution of witches has colored misogyny since the 1400s.
