In this situation, in the early morning of 24 August 1572, the Duke of Guise moved to avenge his father and murdered Coligny in his lodgings. As Coligny's body was thrown into the street, Parisians mutilated the body. The mob action then erupted into the St. Bartholomew's Day massacre, a systematic slaughter of Huguenots that was to last five days. Henry of Navarre managed to avoid death by pledging to convert to Catholicism. Over the next few weeks, the disorder spread to more cities across France. In all, up to 10,000 Huguenots were killed in Paris and the provinces.
