The Count of Poitiers was a noble title in the historical region of Poitiers, located in western France. This title was held by various lords and counts from the early medieval period until the late Middle Ages. The Counts played a significant role in the feudal system, managing lands and providing military support to the king. One of the most notable figures to hold the title was William IX of Aquitaine, who was also a prominent poet and a key player in the politics of Aquitaine. The title eventually became associated with the larger Duchy of Aquitaine, reflecting the region's importance in French history.
