Robert II of France
After a lull in the first two decades of the eleventh century, the movement spread to the north of France with the support of king Robert II of France (reigned 996–1031). There, the high nobility sponsored Peace assemblies throughout Flanders, Burgundy, Champagne, Normandy, the Amiénois, and Berry. The oaths to keep the peace sworn by nobles spread in time to the villagers themselves; heads of households meeting communally would ritually swear to uphold the common peace.
