1572 AD
On August 24, 1572, the Feast of St. Bartholomew, a wave of violence erupted in Paris that would spread across France for weeks. Triggered by the assassination of the Huguenot leader Admiral Gaspard de Coligny, Catholic mobsβencouraged by King Charles IX and his mother Catherine de' Mediciβslaughtered thousands of Huguenots (French Protestants). Estimates of the death toll range from 5,000 to 30,000 in Paris alone, with tens of thousands more killed in the provinces over the following months.
The massacre was a turning point in the French Wars of Religion (1562-1598), a series of eight civil wars that had devastated France. It shocked Protestant Europe and destroyed any hope of reconciliation between French Catholics and Huguenots. The massacre was condemned by some Catholic leaders, including St. Ignatius of Loyola, who reportedly said, 'May God forgive them, for they know not what they do.'
The wars would only end with the Edict of Nantes in 1598, when Henry IV (a former Huguenot who converted to Catholicism) granted religious toleration to the Huguenots. His famous words, 'Paris is worth a Mass,' captured the pragmatism that ended the bloodshed.
