During the reign of Henri III, Maintenon fulfilled a variety of roles for his lord. He was captain of fifty men-at-arms, extraordinary ambassador to España and was appointed
Chambellan in 1580.
Sixth war of religion With the generous
Peace of Monsieur having been broken off in 1577, and civil war resumed. The king's brother
Alençon, now loyal to the crown desired to prove himself by campaigning against the rebels he had fought with in the prior civil war. Henri gave him command of the army, and many of the king's favourites filled its ranks. Not among them however were Maitenon, D'O,
La Guiche and
Georges de Villequier who preferred to stay with the royal court in Poitou. The royal army besieged first
La Charité-sur-Loire and then
Issoire, subjecting each to a brutal sack after they were stormed. As the royal army progressed, it disintegrated, the king having been unable to secure funds from the
Estates General for the campaign, as such a peace was concluded in the
Treaty of Bergerac in September.
Seventh war of religion In 1578, Maintenon was elevated to being a member of Henri's council of state. His attendance would be sporadic, like his brothers. He fought again for the king in the brief civil war of 1580, where he was present at the
Siege of La Fère, the city having been seized by
the Protestant prince of Condé. He arrived on the siege lines in February. After months of siege, the town was willing to provide terms,
Marshal Matignon, in overall command offered a generous settlement to La Fère, hoping to blunt the advantage to the
ligueurs aligned
duke of Aumale who had brought a large contingent to assist with the siege. Having established his new order of chivalry in 1578, Maintenon was included in its fourth induction on 31 December 1581 as a
''chevalier de l'Ordre du Saint Esprit''. Hoping to reform abuses in the kingdom, Henri established an
Assembly of Notables to look through reform packages from 1583 to 1584. Both Maintenon and his brother
Rambouillet participated in the proceedings.
Estates General of 1588 With the
Estates General called, a vicious election campaign got underway, as Henri and the
ligueurs competed through whatever means they had at their disposal for prospective control of the body. In
Chartres, Henri intervened in the election of the noble deputy. He asked the governor of the city whether a candidate had been selected for the area.
the seigneur de Réclainville told him the decision had not yet been made, but that the candidacies of the baron de Courville and sieur de Memelon were being considered. Henri did not feel either of these men could be trusted to support him reliably in the upcoming meeting, he dismissed Memelon as obstinate and a dream, and Courville for a minor military defeat. Henri proposed Maintenon be the deputy for Chartres. Réclainville started stuttering, horrified at the proposal yet unable to voice his opposition. Hesitating to accept, Henri snapped at Réclainville, telling him if Courville was dispatched to the estates at Blois, he would have him executed. Réclainville aceded to the king, and Maintenon was selected. This proved one of the minority of areas in which Henri achieved success, meanwhile the Lorraine family busied itself with engineering
ligueur elections in Bourgogne, Picardie and Champagne. During the Estates General word arrived that
the duke of Savoie had invaded France and seized
Saluzzo, the final Italian possession France held from the
Italian Wars. Maintenon rallied the Second Estate behind him, convincing them of his royalist argument that not only should they seize Saluzzo back from Savoie they should unite the kingdom behind a war against a hereditary enemy Spain. The First and Third Estates were not as easily won to Maintenon's arguments, and favoured focusing the kingdoms military efforts in an internal war against heresy, the noble Second Estate was eventually brought back into line with this perspective. Henri was humiliated, and incorrectly saw the hand of
the duke of Guise behind the original invasion.
Assassination of the duke of Guise Henri could no longer tolerate the humiliations put upon him by
the duke of Guise and the
ligue and resolved to take some action against them by December 1588. On 18 December he took council with
Marshal Aumont,
the future Marshal Ornano and two of the Angennes brothers, Maintenon and
Rambouillet. At the council three of the four present spoke in favour of assassinating the duke. After some more consultation this was the course of action Henri decided to pursue. Henri convened his council on 23 December, present were Maintenon, Rambouillet, D'O, Aumont,
Retz the archbishop of Lyon
Pierre d'Épinac; the cardinals of
Guise,
Vendôme and
Gondi; and the duke of Guise. Guise was called off to a side room, so that he might meet with the king, shortly thereafter he was cut down. Writing sometime after, one of the duke's young valets puts particular responsibility in the hands of Maintenon and his brother Rambouillet for what had transpired. With the assassination accomplished, Henri again reconfigured his council to ensure its reliable trustworthiness. Maintenon and Rambouillet were both among those who maintained their position in the king's inner circle. Maintenon accompanied the king as he moved from Blois to
Tours. In Tours Henri established an exiled version of the Paris
Parlement filled with the royalist deputies expelled from the
ligueur controlled Paris
Parlement. Maintenon was present for the
lit de justice that Henri opened the chamber with. ==Reign of Henri IV==
