St. Bartholomew’s Day Massacre Summary

  • Last updated on November 11, 2022

With King Charles IX’s approval, France’s Catholic nobles murdered several Huguenot leaders and thousands of other Protestants in an attempt to eliminate Protestantism in the nation once and for all. Instead, the massacre renewed the civil wars of religion, severely undermined the crown’s authority, and created profound social disorder throughout France.

Summary of Event

In 1562, a series of civil wars between Huguenot Huguenots and Catholic Catholicism;France forces broke out in France. These wars, known as the French Wars of Religion, Religion, French Wars of (1562-1598) were to last, with intermittent periods of calm, until the 1598 Treaty of Vervins Vervins, Treaty of (1598) and Henry IV’s Edict of Nantes, Nantes, Edict of (1598) which together created a peace and established limited freedom of religion in the country. The immediate causes of the wars were the 1559 decision by Queen Catherine de Médicis to persecute and execute leading Protestants and the 1562 massacre by troops of the Guise family of numerous Protestants in the French provincial city of Vassy.

After several years of intense fighting, the 1568 Treaty of Longjumeau Longjumeau, Treaty of (1568) put a temporary end to the civil war. Both sides, however, continued their intrigues, and war broke out again in September, 1568. Charles IX adopted a strong anti-Huguenot policy out of fear that the Huguenots might ally with Dutch Protestant rebels, who had revolted against the Spanish occupation of the Netherlands, and provoke a Spanish attack on France. This fear of a possible Spanish invasion of France played a decisive role in August, 1572, when the king approved what came to be known as the St. Bartholomew’s Day Massacre. Meanwhile, at Jarnac on March 13, 1569, Catholic forces won a decisive victory in which the Huguenot leader, Louis I of Bourbon, prince of Condé, was captured and later assassinated. Admiral Gaspard II de Coligny then became leader of the Huguenots. When Coligny’s forces marched on Paris in June, Charles made peace.

Religious tolerance was nominally established once again by the Treaty of St. Germain St. Germain, Treaty of (1569)[Saint Germain, Treaty of (1569)] , and certain towns were given to the Huguenots as strongholds. The most important provision of this treaty was a marriage alliance between Marguerite of Valois, the sister of Charles IX, and Henry of Navarre, the leading Huguenot prince and son of Antoine de Bourbon. Henry was in the line of succession to the French throne. Suspicious of Catherine de Médicis and Charles IX in spite of this treaty, Coligny, Henry of Navarre, and his mother Jeanne d’Albret hesitated to come to court. Their fears were perfectly reasonable, because Catherine de Médicis and Charles IX had already approved several political assassinations, and their promises therefore seemed meaningless. Coligny, however, finally arrived at the royal court in September of 1571, and he was well received.

Coligny persuaded Jeanne d’Albret to accept the marriage proposal, and the marriage of Marguerite of Valois and Henry of Navarre was planned for August 18, 1572. Jeanne d’Albret joined the court in March, 1572, but when she died shortly afterward, her fellow Huguenots suspected that she had been poisoned. This may well have been the case. Mistakenly believing that Catherine de Médicis and Charles IX would not risk killing them since to do so would ensure a resumption of the civil war, Coligny and Henry of Navarre (who had entered Paris in July, 1572, with an entourage of Huguenot nobles) did not realize that they were walking into a carefully prepared trap.

During the early summer of 1572, Huguenot forces had confirmed Charles IX’s worst fears by supporting a Dutch uprising against the Spanish occupation of their homeland. Charles IX believed that King Philip II of Spain now had an excuse for invading France if that was his plan. What exactly transpired next is not entirely clear, but historians generally agree that sometime before the wedding of Marguerite and Henry, Catherine de Médicis decided to have her Catholic forces assassinate Coligny and other leading Huguenots. The presence of so many Protestants at the royal court gave her a unique opportunity to reduce Protestant influence in France with a single stroke. The Guises hired an assassin named Maurevert to kill Admiral Coligny.

On August 22, four days after the wedding, Maurevert shot Coligny. Coligny, however, survived the attack. The complicity of the Guises was quickly established, and the Huguenots demanded justice from King Charles IX. It has never been determined whether Charles IX approved the failed assassination of Coligny. However, it is known that, faced with the ruin of her plans, Catherine de Médicis and her advisers now urged Charles IX to approve another murder attempt on Coligny for the good of the kingdom. Plans of a fictitious Huguenot conspiracy were shown to the king.

Charles gave in to their arguments. It was reported that he ran from the room shouting: “Kill them all, so that none will return to reproach me!” By thus approving the mass murder of his own subjects, King Charles IX guaranteed a resumption of the French civil wars and his own place in history as a monarch who had committed crimes against humanity. With the help of her son François, duke of Alençon (better known by his later title, duke of Anjou), Catherine drew up a list of prominent Huguenots who were to be slain and made arrangements with Claude Marcel, a former mayor of Paris, to recruit thugs and common criminals for the indiscriminate slaughter of all the Protestants who had remained in the city after the wedding. Early on the morning of August 24, Coligny was stabbed to death in his room, and his body was mutilated. Henry of Navarre and Henry I of Bourbon, prince of Condé, were forced to recant their religious beliefs under threat of death.

Dozens of Huguenot nobles were killed in the courtyard of the Louvre. Criminals led by the duke of Alençon and Henry I of Lorraine, duke of Guise, then went through the city systematically attacking and slaying prominent Huguenots. These gangs then began killing Protestants all over Paris. Pregnant women and even children were tortured and murdered. Peter Ramus, the leading French philosopher of the era, was killed, and the English ambassador to France barely escaped with his life. King Charles IX accepted full responsibility for this butchery, and he ordered his troops to carry out similar massacres in provincial cities. He claimed that Huguenots had plotted against his throne. However, only the most fanatical supporters of Catherine de Médicis and the Guises believed this lie.


It has been impossible to determine the precise number of people murdered during the St. Bartholomew’s Day Massacre. Contemporaries spoke of between 2,000 and 100,000 victims. An extremely conservative estimate is that at least 7,000 French Protestants were killed as a result of the criminal activity ordered by King Charles IX.

News of the massacre quickly spread throughout Europe. In Rome, Pope Gregory XIII had a solemn thanksgiving sung. Many French Catholics, however, were revolted by the killings. Protestants throughout Europe were appalled by this state-sponsored terrorism. The eminent French Protestant writer Theodore Beza, who was then living in Geneva, eloquently summarized the general Protestant reaction by writing that those responsible for this massacre would be “held in perpetual execration.” Both Catholic and Protestant historians have agreed with Beza’s judgment.

Much to the displeasure of Catherine de Médicis and Charles IX, the massacre of St. Bartholomew’s Day did not produce the effect they had expected. The civil war quickly resumed, and it did not end for another twenty-five years. Having approved the political assassinations, Charles IX launched a cycle of violence that would end in the assassinations of his two successors: Henry III in 1589 and Henry IV in 1610.
