The assassin was immediately killed by the returning attendants, but Henry III, after pleading with Navarre that his own conversion to Catholicism was the only way to save the Kingdom from protracted civil war, died early in the morning of the following day.

[1] Although traditionally seen by both Protestant and Royalist as a brutal act motivated by religious fanaticism, the regicide was viewed with very different feelings by the nobles and commons of Paris, who had expelled the King during the recent Day of the Barricades, and by the many partisans of the League.

Catherine de Guise, Duchess Montpensier, who had sanctioned Clément's plans to avenge the recent assassinations of her brothers, is said to have been particularly overjoyed and to have immediately boasted of her own role in plotting the regicide.

[3] Clément was even seen in some circles as a martyr and his actions were praised as tyrannicide by Pope Sixtus V, as well as the Jesuit historian and political philosopher Juan de Mariana, S.J.
