In what became known as the St. Bartholomew's Day Massacre of 24 August – 3 October 1572, Catholics killed thousands of Huguenots in Paris. Similar massacres took place in other towns in the weeks following. The main provincial towns and cities experiencing the Massacre were Aix, Bordeaux, Bourges, Lyon, Meaux, Orleans, Rouen, Toulouse, and Troyes. Nearly 3,000 Protestants were slaughtered in Toulouse alone. The exact number of fatalities throughout the country is not known. On the 23–24 August, between about 2,000 and 3,000 Protestants were killed in Paris and between 3,000 and 7,000 more in the French provinces. By 17 September, almost 25,000 Protestants had been massacred in Paris alone. Outside of Paris, the killings continued until the 3 October. An amnesty granted in 1573 pardoned the perpetrators.
The Siege of Beziers and the Siege of Magdeburg, too, will provide insight into christian on christian savagery.
