Picardy

Picardy was a historical region of northern France whose medieval towns included Amiens, Arras and Abbeville, rather than a single principality. During the Hundred Years' War it was a centre of the Jacquerie revolt in 1358, and the 1435 Congress of Arras brought French, English and Burgundian representatives to the region.
