The book by the American scientist Henry Charles Lee is recognized as one of the best, complete and detailed publications dedicated to such an interesting and controversial period in the history of the Church as the Inquisition. This work, which once caused a real sensation in Europe, is a deep and impartial study of the reasons for the emergence of the Inquisition, the biographies of its servants, archival documents from different countries and times. The proposed publication will be of interest not only to history buffs, but also to all those who are interested in studying politics and the laws of government. Uncontrolled, categorical, autocratic, not knowing any other law except the only one: this is how I want, this is what I command, and let my will be the argument, the Inquisition for many centuries was a symbol of absolute power, a weapon in the fight against freedom of conscience, religion, and especially freedom thoughts.
