In short
On August 24, 1572, Catholic mobs in Paris began systematically hunting and killing Huguenots-French Protestants-in a massacre that spread to other cities over weeks. Queen Catherine de' Medici, mother of King Charles IX, was widely believed to have orchestrated the violence, though her exact role remains debated by historians. The bloodshed killed somewhere between 5,000 and 30,000 people and hardened the religious fault lines that would fracture France for decades.
How it unfolded.
The five-minute version
What actually happened.
The Saint Bartholomew's Day massacre in 1572 was a targeted group of assassinations and a wave of Catholic mob violence directed against the Huguenots during the French Wars of Religion. Traditionally believed to have been instigated by Queen Catherine de' Medici, the mother of King Charles IX, the massacre started a few days after the marriage on 18 August of the king's sister Margaret to the Protestant King Henry III of Navarre. Many of the wealthiest and most prominent Huguenots had gathered in largely Catholic Paris to attend the wedding.
