Summary: 1685 was a watershed year for events that would lead to what we call the Enlightenment. France´s Sun King Louis XIV revoked the Edict of Nantes and initiated a policy of religious persecution of Protestants. In England, the Catholic James II assumed the throne to the horror of the protestant majority in Parliament. The French philosopher Pierre Bayle wrote his groundbreaking defense of religious tolerance “Commentaire Philosophique” and John Locke wrote his Letter Concerning Toleration.
