Burning Times: This is a word used to describe the execution of the witches during their persecution from the Middle Ages onwards. Most executions were in fact by hanging, not burning. While it is claimed that thousands and even millions were killed, a small fraction were actually witches. Many were heretics or Christians accused of witchcraft by those who disliked them, from circa 1000 CE through the 17th century. This turned into an extremely profitable venture, as all land and property was seized from the accused individual and portions given to the accuser (in reward fashion) and the remainder seized by the church officials. Historians indicate that the majority of people tortured and murdered were women and children.
