Answer:
The Treaty on Tolerance is a work that François-Marie Arouet, better known as Voltaire, wrote and published in 1763 in Ferney-Voltaire Castle, after the death of the Huguenot Jean Calas, unjustly accused and executed on March 10, 1762 for the murder of his son.
In this work, Voltaire invites tolerance among religions, attacking with harsh religious fanaticism, especially that of the Jesuits. The French philosopher had studied in his youth in a school of this order, where he stood out for his wit and application. Voltaire defends in this Treaty the freedom of cults, and criticizes religious wars as a violent and barbaric practice. He argues that no one should die for his ideas, and considers fanaticism a disease that must be combated and extirpated.
