parish of the Auxerrois region during the early Middle Ages: it is cited several times in a manuscript started in the late 9th century, the Gesta episcoporum autissiodorensium, as a station in the respective itineraries of Bishops Aunarius (Saint Aunaire, late 6th century), Tetricius (Saint Tétry, late 7th century), and Gerrannus (, early 10th century). The land of Thury was part of the battlefield of the Battle of Fontenoy (841). Echoes of the battle survive in toponyms around the village to this day. For example, the name of the nearby hill and wood of Roichat refers to King Charles the Bald (le roi Charles), who had established his temporary base camp there. After 1000 CE, lordship over the land of Thury alternated between the County of Auxerre, its Bishop (long a territorial lord as well), the Count of Champagne, the Count of Nevers, and occasionally the Duke of Burgundy. There is no trace of a specific lordship of Thury during that period though, and it is not clear how significant the village was if indeed it remained inhabited. Late Middle Ages and Early Modern Era In any event, Thury and the surrounding region suffered greatly during the Crisis of the Late Middle Ages, including the Hundred Years' War. It was ravaged by roaming armies, especially in 1411 during an episode of the Armagnac–Burgundian Civil War and in 1423 in the run-up to the Battle of Cravant. Security did not return until well after the Peace of Arras in 1435. Thury was (re-)populated by newcomers (known as horsains, "foreigners") from other parts of the Kingdom of France. The village castle was built around that time. The church was rebuilt in the late 15th century and completed in 1503, with the portal sculpted in 1521. In 1542, Francis I granted Thury by letters patent the right to hold a weekly market and three fairs a year (and also to erect fortifications around the village), which was reaffirmed by Henry III in 1576 and Louis XIV in 1669. The region suffered from renewed insecurity during the French Wars of Religion, as it was on the way of the armies of John Casimir of the Palatinate-Simmern in 1576, of Count in 1587, and of in 1617 during the aristocratic uprising against Concino Concini. The hamlets of Grangette and Colangette, despite being geographically very close to Thury, where under separate jurisdiction as lands of the
