Overview
Comté de Vermandois; capital Saint-Quentin. A Picard county held by a Carolingian-descended house (the Herbertians) that lent it prestige. The heiress Eleanor of Vermandois brought it into play among the great northern houses; it was absorbed piecemeal into the royal domain under Philip II Augustus c. 1213–1215, an important step in Capetian expansion in the north.

Its bibliography names the English Wikipedia articles for each territory as the primary basis, cross-checked against Encyclopædia Britannica and specialist snippets, and flags entries built on unreliable foundations — the 911 treaty of Saint-Clair-sur-Epte known only from Dudo of Saint-Quentin, and Arnaud Amalric's alleged order at Béziers attested only decades after the fact.
