After the failure of Raymond Trencavel II in 1240, Raymond VII of Toulouse had one last hope of popular uprising in the Languedoc against the French occupiers and the Inquisition. The uprising was planned for 1242, supported by the Holy Roman Emperor, James I King of Aragon, Henry III King of England , Roger IV Count of Foix, Raymond Trencavel II, and other allies.
It proved a disaster. The Holy Roman Emperor kept delaying until it was too late. Henry III was defeated at Taillebourg by Louis IX King of France. The Aragonese forces were not enough to galvanise the exhausted population, and the new Count of Foix deserted his family's ancient ally, sealing both their fates.
The only achievement of note was the killing of a few widely hated Inquisitors at Avignonet, along with their retinue, during the night of 28 May 1242 by soldiers from Château of Montségur ( Montsegùr) led by Pierre-Roger de Mirepoix. The removal of these Inquisitors was enormously popular. Church bells were rung to celebrate the event as the solders passed through villages on their way home.
The Château at Avignonet, where the Inquisitors were lodging, belonged to Raymond VII of Toulouse, and was kept by his his brother-in-law, Raymond d'Alfaro.
The events at Avignonet prompted the final notable action of the war - the famous siege of the Château of Montségur ( Montsegùr) in 1243-4. Many of those who had participated in the killing of the Inquisitors were captured at Montsegùr and interrogated by the Inquisition. This is why historians have a remarkable amount of detail about them and their movements.
Today the castle where the killing of the Inquisitors took place is gone, but the church is built on the site of the castle chapel. As everywhere else in the Languedoc, the people here are still proud to fly the flag of their ancient count. The fact that the church here stands on the site of his castle is commemorated in a small stained glass window (shown above) depicting his arms surmounted by his coronet with a star above. It may just be a coincidence, but the Cathars thought of stars as perfected souls in heaven.
Many attempts have been made to have the dead Inquisitors elevated to sainthood - normally a formality for Catholic clergy killed for "upholding the faith" - but the Inquisitors were widely hated and a suitably discreet time for their canonisation has never been found. The townspeople have still not forgotten that their Catholic ancestors were punished for their complicity by the Church for a generation after the killing.
