The Renaudie affair (1559–1560)
King Henry II died in 1559 and was succeeded by his son François II, then only 15. Though he was old enough to rule without a regent, he delegated his power to the House of Guise. Jean du Barry, Lord of La Renaudie, a friend of Jean's, then imagined removing the queen-mother and the young king from the influence of the Guise.
La Renaudie took the lead in the conspiracy, which originated in December 1559, in Geneva, shortly after the execution of Anne du Bourg. Its goal was to impose around the young king a council of regency, where the princes of blood, particularly Condé, would hold the first place. Antoine de Bourbon was opposed to it as well as Calvin; it does not seem that the latter nor Théodore de Bèze were really informed of the real aims of the conspirators. La Renaudie was personally angry with François II and Charles de Guise who had his brother-in-law arrested and executed. He gave himself as accomplices a few friends, Raunay, Baron Charles de Castelnau, François II, Baron d'Aubeterre (Jean V de Parthenay's brother-in-law), Edme de Ferrière-Maligny (brother of Jean II de Ferrières), Captain Mazères, but also the father of Agrippa d'Aubigne. If the Guises resisted, the conspirators promised to massacre them. La Renaudie, who linked up with Soubise at the siege of Metz, confided to him his intention of seizing the king from the month of September 1559, at a time when the conspiracy was far from having taken shape.
A first assembly of conspirators was held in Nantes in February 1560, and their troops, nearly 500 men, split up with the intention of moving towards Blois, Tours, and Orléans. Originally scheduled for 10 March 1560; the operation was postponed until 17 March. However, from 12 February, the Guises, warned by the Parisian lawyer with whom La Renaudie was staying, were made aware of the plot. They decided to take refuge in Amboise. Condé d'Andelot, Coligny, and Odet de Chatillon—taken into confidence by La Renaudie—negotiated an amnesty for Protestants except for the conspirators with Guise.
On 15 March, Jacques de Savoie, Duke of Nemours, seized the castle of Noizay, where some of the conspirators had gathered. Condemned for the crime of lèse-majesté, Castelnau, Mazères, and Raunay died beheaded or hanged at the windows of the castle of Amboise. For the next few days, La Renaudie was nowhere to be found. Jean V, for his part, was retained by the service of the queen mother, who interrogated Jean V and tried to ascertain where his friend was hiding.
Conversation between the Queen mother and Jean V de Parthenay. Jean replied,
When I know, I'd rather be dead than say it.
The Queen Mother assures him that he need fear nothing if La Renaudie has done nothing against the King. Jean V de Parthenay replied,
I know well that it will be found that he acted against the king, since he acted against those of Guise, because today in France it is a criminal lèse-majesté to have acted against them, of as indeed they are the ones who are kings.
The conspiracy ended in a massacre. Bertrand de Chandieu's troops were destroyed when they marched towards Ambroise on 17 March. La Renaudie was killed on 19 March.
