Witchcraft

In 1692, a resident of Salem Village asked for help for his wife from several girls in the village who were said to have the power to detect and cure disease. After visiting her, the girls claimed that several people in Andover had bewitched her. During the course of the frenzy that swept Salem Village and surrounding communities, more than 40 Andover citizens, mostly women, were eventually accused of being in league with Satan. About a quarter of them were condemned to death, and as many as three were executed. Many of the rest were imprisoned for months.
