There are many theories towards the behavior that the young girls, who accused so many of practicing witchcraft, experienced at the beginning of the Salem Witch Trials in 1692. Among the theories are adolescent hysteria and ergot poisoning. The Salem Witch Trials is an example of the dangers of isolationism, religious extremism, false accusations and lapses in due process. Historians consider the trials to have been highly influential in subsequent United States history. After the trials had concluded, Jurors and magistrates apologized. Restitution was made to the victims' families and a Day of Fasting and Remembrance was instituted.
