"The Witch-Cult in Western Europe" is an anthropological study by Margaret Alice Murray, published in 1921. This book presents Murray's controversial theory that the witch trials of Europe were not merely a result of superstition and hysteria, but were actually targeting a secret, pre-Christian pagan religion that worshipped a horned god. Murray's hypothesis, known as the witch-cult theory, suggests that this ancient religion was practiced in secret by covens of witches who held regular meetings and rituals. The book delves into historical records, trial documents, and folklore to support Murray's claims, offering a detailed analysis of the practices, beliefs, and organizational structure of this supposed witch-cult. Although her theories have been widely discredited by modern scholars, "The Witch-Cult in Western Europe" remains a significant work in the history of witchcraft studies and has influenced the development of modern Wicca and neopaganism.
