Cambrésis

Cambrésis was an imperial prince-bishopric centred on Cambrai. Its bishop held comital rights, and in 1337 Bishop Guillaume d'Auxonne ruled the city and its surrounding county.

In 1339 Edward III of England besieged Cambrai during the Hundred Years' War, using cannon, but Guillaume sided with Philip VI of France and held out until the English withdrew. Burgundy dominated Cambrésis from the fifteenth century. France took Cambrai in 1677, and the Peace of Nijmegen annexed Cambrésis in 1678; the bishopric's temporal lands were dissolved in 1789.
