A witch is a person who practices witchcraft or magic. Traditionally, the word “witch” was used as an accusation. Witches were accused of bewitching people, or casting spells to control them. 

Today, followers of Wicca practice witchcraft and worship nature. Some call themselves witches. Note that the practicioners of Wicca are completely unrelated to the historical Witches, this article is about.

History 
Most indigenous peoples throughout history have had some beliefs about spirits and believed that certain individuals could gain magical powers through herbs or spirits. However, these individuals were not called 'witches' until indigenous people had contact with western ideas. Spirits and people who interacted with them were not always viewed negatively in indigenous societies.

The Malleus Maleficarum 
The Malleus Maleficarum, a book published in 1487, fueled panic over witchcraft. It was written by a German Catholic clergyman named Heinrich Kramer. The book was a witch-hunting manual that explained how to persecute witches. It suggested using torture to get accused witches to confess to witchcraft. It also encouraged  burning “witches” at the stake. 

The new technology of the printing press made it possible for Malleus Maleficarum to be mass produced. The book was printed 29 times before 1669 - more than any other book except the Bible. As a result, its ideas spread throughout Europe. These ideas were common in Europe for several centuries after the book was published.

The book says that three things are needed in order to create witchcraft: the witch’s evil intentions, the Devil’s help, and God’s permission.

Witch Hunts 

Many women throughout Europe and in South America were killed by witch hunts. Historians debate how many women were killed. Because of poor record keeping, it is impossible to know exactly how many victims there were. Also, historians have different opinions about what regions and time frames should be included when estimating how many women were killed in witch hunts.

The entire persecuting legal system - "judges, ministers, priests, constables, jailers, judges, doctors, prickers, torturers, jurors, executioners" - were nearly all male. Meanwhile, the victims were overwhelmingly female. For this reason, some scholars call the witch hunts a "gynocide". In the documentary The Burning Times, Thea Jensen calls this period in history a "Women's Holocaust".

Modern understanding 

In the 20th century, many people made a new attempt to understand witchcraft. Some say that witches were in fact wise women who were hunted down by the Catholic Church - mostly for their knowledge about how to treat certain diseases using herbs. Some followers of pagan religions like Wicca began to call themselves witches. This has led to a new understanding of what a “witch” really is.

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.

Silvia Federici tied the witch hunts to a history of the female body in the transition to capitalism.

Witchcraft and accusations of witchcraft are still very common in some parts of West Africa.

Witch crimes in the Malleus Maleficarum 
Control of procreation was a constant theme, as was medical knowledge:

Concerning Witches who copulate with Devils. Why is it that Women are chiefly addicted to Evil superstitions?

Whether Witches may work some Prestidigatory Illusion so that the Male Organ appears to be entirely removed and separate from the Body.

That Witches who are Midwives in Various Ways Kill the Child Conceived in the Womb, and Procure an Abortion; or if they do not this Offer New-born Children to Devils.

How Witches Impede and Prevent the Power of Procreation.

How, as it were, they Deprive Man of his Virile Member.

Of the Manner whereby they Change Men into the Shapes of Beasts.

Of the Method by which Devils through the Operations of Witches sometimes actually possess men.

Of the Method by which they can Inflict Every Sort of Infirmity, generally Ills of the Graver Kind.

Of the Way how in Particular they Afflict Men with Other Like Infirmities.

How Witch Midwives commit most Horrid Crimes when they either Kill Children or Offer them to Devils in most Accursed Wise.

She died in 1634, probably from the plague.
