The Affair of the Placards (French: Affaire des Placards) was an incident in which anti-Catholic posters appeared in public places in Paris and in four major provincial cities, Blois, Rouen, Tours and Orléans, in the night of the 17 to 18 October 1534. One of the posters was posted on the bedchamber door of King Francis I at Amboise, an affront and a breach of security that left him shaken. The Affaire des Placards brought an end to the conciliatory policies of Francis, who had formerly attempted to protect the Protestants from the more extreme measures of the Parlement de Paris, and also of the public entreaties for moderation of Philip Melanchthon.
