Assassination of Henry III of France (1589) by Jacques Clément

The assassination of Henry III of France took place at Saint-Cloud, near Paris, on 1 August 1589, when the Dominican friar Jacques Clément stabbed the king during a private audience. Henry died the next morning, the last king of the Valois dynasty that had ruled France since 1328. His death left the Protestant Henry of Navarre as heir to the throne in the middle of a religious civil war.

Background

Henry III had come to the throne in 1574 during the French Wars of Religion. By 1588 he had lost control of Paris to the Catholic League, a movement determined to prevent his Protestant cousin, Henry of Navarre, from succeeding him. In December 1588 Henry III had the League’s leader killed, as described in the article on the Assassination of the Duke of Guise.

The murder made the king hated by militant Catholics. The Sorbonne declared his subjects freed from obedience, preachers denounced him as a tyrant, and the pope excommunicated him for killing a cardinal. In April 1589 Henry III allied with Navarre, and by late July their combined army, commonly estimated at 30,000 to 40,000 men, was besieging Paris from Saint-Cloud.

The assassination

Jacques Clément, born around 1567 in Burgundy, was a young friar of the Dominican convent in Paris. Inspired by League preaching that killing a tyrant could be lawful, he resolved to kill the king. He obtained letters of introduction, some from royalist prisoners in Paris, and left the city on 31 July.

On the morning of 1 August he was brought before the king, who received him while seated on his close-stool, a common practice for informal audiences at the time. Claiming to carry a confidential message, Clément approached and stabbed Henry in the lower abdomen with a knife hidden in his sleeve. The king pulled out the blade and struck back, and the guards killed Clément on the spot. His body was later quartered and burned.

At first the wound did not seem fatal, but infection set in. Henry summoned his officers, recognised Henry of Navarre as his successor and urged them to swear loyalty to him, while advising Navarre to convert to Catholicism. He died in the early hours of 2 August 1589, aged 37.

Key people

• Henry III (1551–1589): king of France from 1574 and earlier briefly elected king of Poland.
• Jacques Clément (c. 1567–1589): the Dominican friar who killed him.
• Henry of Navarre (1553–1610): Henry III’s Protestant heir, who became Henry IV.
• Charles, Duke of Mayenne (1554–1611): leader of the Catholic League after the death of his brother, the Duke of Guise.

Consequences

In League Paris, Clément was celebrated as a martyr, and Pope Sixtus V spoke approvingly of the deed in a consistory. Many Catholic nobles in the royal army refused to serve a Protestant king, and Navarre had to lift the siege of Paris.

Henry IV fought on, winning victories at Arques in September 1589 and at the Battle of Ivry in March 1590. He converted to Catholicism in July 1593, entered Paris in March 1594 and ended the wars with the Edict of Nantes in 1598, which granted Protestants limited toleration. He too was murdered by a Catholic fanatic, in 1610.

The debate over killing a tyrant

The murder of Henry III came at the height of a long argument in Europe about whether subjects could resist, or even kill, an unjust ruler. Protestant writers had developed theories of resistance after the St Bartholomew’s Day Massacre of 1572. By the late 1580s Catholic League preachers and pamphleteers had turned similar arguments against a Catholic king whom they accused of betraying the faith by allying with heretics and killing the Guise brothers.

Clément’s act was praised in League sermons and pamphlets, and some writers presented him as a new Judith, the biblical heroine who killed an enemy general. The Spanish Jesuit Juan de Mariana later discussed the case in his treatise De rege et regis institutione (1599), in a passage widely read as approving tyrannicide in some circumstances. After the murder of Henry IV in 1610, such ideas were condemned in France, and royal writers stressed the sacred, untouchable nature of kingship.

Myths and facts

“Clément acted on orders from the League’s leaders.” Royalists accused the Duke of Mayenne and his sister, the Duchess of Montpensier, of encouraging Clément. Some contacts with League figures are reported, but no clear proof of a planned order has survived.

“Henry III died instantly.” He lived for most of a day after the stabbing, long enough to arrange the succession and receive the last rites.

Why it matters

The murder of Henry III ended the Valois dynasty. It brought the Bourbons to the throne and set the stage for the compromise peace under Henry IV, while showing how far religious radicalism had gone in justifying the killing of kings.
