The Counts of Vermandois were noble rulers in the region of Vermandois, located in northern France. This title emerged in the early medieval period, particularly during the 9th century, as part of the feudal system. The counts played a significant role in local governance and military leadership, often aligning with powerful families and the French monarchy. One notable count was Hugh of Vermandois, who was a prominent figure in the 10th century. The title eventually became associated with various noble houses, including the House of Capet, influencing the political landscape of France during the Middle Ages.
