At the turn of the 13th century, "Aigrefeuille" became a lordship that had already acquired a certain importance in "Aunis", and the lord, Guillaume Maingot, was sire of "Surgères". He was also the first known lord of "Aigrefeuille". "Aigrefeuille" was then a "considerable parish of "Aunis" and one of the oldest Châtelains of the barony of Surgères with the right of "chasteau" and a fortress with high, medium, and low jurisdiction, honorific rights and the first bench in the church". It was from this time that the village became a busy market, since before the 15th century it had already received approval to build a hall.
