The Christian death cult in 15th to the 18th centuries. 200,000 women murdered because a witch makes Christians cry.

This is from Wikipedia. I also recommend "The Dark Side of Christian History" by Helen Ellerbe.

A witch-hunt is a search for persons labelled "witches" or evidence of witchcraft, often involving moral panic or mass hysteria. The classical period of witch-hunts in Early Modern Europe and Colonial North America took place in the Early Modern period or about 1450 to 1750, spanning the upheavals of the Reformation and the Thirty Years' War, resulting in an estimated 35,000 to 100,000 executions. Including illegal and summary executions it is estimated 200,000 or more "witches" were tortured, burnt or hanged in the Western world from 1500 until around 1800. The last executions of people convicted as witches in Europe took place in the 18th century.
