The Capitulary of Quierzy was a capitulary of Emperor Charles II that had a series of measures to safeguard the administration of his realm during his second Italian expedition, as well as directions for his son Louis the Stammerer, who was entrusted with the government during his father's absence. It has traditionally been seen as the basis on which the major vassals of the kingdom of France such as the counts of Flanders, were enabled to become more independent.
