Torsåker is a parish in Ångermanland, in northern Sweden, and in 1675 it was the site of the largest single execution for witchcraft in Swedish history. The parish record names a large group, the great majority of them women, beheaded and then burned on one day.
It belongs to a national panic, called in Swedish the Great Noise, which ran through the 1660s and 1670s and had a distinctive engine. The accusations turned on children, who were asked whether they had been carried at night to Blåkulla, a place in Swedish folk belief where witches were said to gather, and who were asked to name who had carried them. Children questioned that way by adults who plainly want an answer will produce one, and each name produced another round of questioning.
At Torsåker the identification is reported to have been done by boys who walked the assembled parish and pointed. Whatever the exact procedure, the result was a mass condemnation from a small community, and the parish never recovered its population balance.
The Swedish panic ended when the central authorities in Stockholm examined the children's testimony properly, found it contradictory, and stopped the commissions. Some of the child witnesses were themselves punished afterwards for false testimony.
