1431: Beaumont and Vivonne

From The Law of Treason and Treason Trials in Later Medieval France:

Little is known about the prosecution of treason during the first fifteen years of Charles VII‘s reign. A few minor cases only came before the Parlement of Poitiers. Struggling to consolidate his position against the Anglo-Burgundians, Charles VII appears to have tacitly approved of, even to have subtly encouraged, court intrigues. But when political machinations went beyond certain limits, as was the case with Louis d’Amboise, vicomte of Thouars, Andre de Beaumont, baron of La Haye, and Antoine de Vivonne, Charles VII did not hesitate to act with the full authority at his disposal. During the winter of 1429-30 Amboise, Beaumont and Vivonne plotted not only to seize Georges de La Tremoille, the most powerful lord at court, and to kill him if necessary, but also to take the king into custody. Amboise was one of Artur de Richemont‘s staunchest allies, and one does not have to look very hard to see the hand of the constable, then fallen from grace, in this conspiracy to take control of the government. Amboise, Beaumont and Vivonne were arrested in mid-November 1430, but it seems that not all the details of their treason were known to the king at that time. When Charles VII decided to take Amboise with him from Loches to Saint-Aignan, Amboise managed to send word to his intimates and advised them to ambush the royal party in order to free him. It was the king’s discovery of this communication that sealed Amboise’s fate. He, Vivonne and Beaumont were subsequently imprisoned at Poitiers. Charles VII then commissioned the presidents and lay councillors of the Parlement there, along with several members of the grand conseil, to conduct their trial. On the advice of his commissioners Charles VII himself then condemned the three traitors to death, with confiscation of their property. This procedure was a compromise between the king’s personal act of justice and condemnation by a court, and was to be a regular feature of the prosecution of treason in the reigns of Charles VII and Louis XI. On 31 May 1431 Beaumont and Vivonne were executed, but Charles VII commuted Amboise’s death sentence to a term of imprisonment ‘at our good pleasure’; and Amboise’s children were spared the penalty of complete disinheritance that would ordinarily have ensued. In not having Amboise executed Charles VII demonstrated for the first time the clemency towards members of the higher nobility that was a distinct characteristic of his rule. In 1434, at the intercession of Yolande d’Aragon and Charles d’Anjou — La Tremoille had since fallen from power and the Angevins were now in the ascendants at court — Charles VII released Amboise from prison and restored to him all of his property except for the castellanies of Chaumont, Chateau-Gontier and Amboise.
