On August 18, 1572, the Catholic and Protestant royal houses of France were joined when Henry of Navarre, the leading Huguenot prince, married Margaret of Valois, sister of King Charles IX, in a wedding meant to seal the fragile peace that had ended the third of France's religious wars two years earlier. Thousands of Huguenot nobles had traveled to overwhelmingly Catholic Paris for the celebrations. Four days later, an assassin's bullet wounded but failed to kill the Huguenot military leader Admiral Gaspard de Coligny, whose growing influence over the young king had alarmed the Catholic court, including the king's mother, Catherine de Medici.
Fearing a Huguenot uprising in retaliation, the royal council authorized the killing of Coligny and a small number of Huguenot leaders in the early hours of August 24, the feast of Saint Bartholomew. What began as a targeted strike escalated within hours into an indiscriminate massacre as armed Catholic militia and mobs moved through Paris killing Huguenots in their homes and in the streets; Coligny himself was thrown from a window and his body mutilated. Several thousand were killed in Paris alone over the following days.
News, and in some cases direct orders from the crown, carried the killing into the provinces over the following weeks, with major massacres recorded in Orleans, Meaux, Lyon, Rouen, Bordeaux, Toulouse and elsewhere before the violence finally subsided in October. The massacre shattered a decade of uneasy peace efforts and convinced many Huguenots that no royal promise of toleration could be trusted, reigniting the French Wars of Religion for a generation.
