How did the Catholic Church fight heretics?

The Catholic Church of the Middle Ages imposed on the common people the opinion that one must live in poverty, this is the only way God will help. At the same time, the clergy themselves lived in luxury, performed expensive church rituals and collected taxes from the population. All this caused a wave of popular indignation. The Inquisition is created – a secret church court. The Inquisition arranges interrogations for heretics, subjects them to terrible tortures. Mass burning at the stake was practiced. If initially the victims of the church court were dissatisfied with the policy of the church, later attractive women were accused of witchcraft, children with disabilities were ranked among the children of the devil. They also faced the death penalty. Scientists, astronomy, physics and chemistry workers were burned at the stake.
