The Count of Toulouse was a title held by the rulers of the region of Toulouse in southern France during the medieval period. This title was significant in the feudal system, where counts governed territories on behalf of the king. The Counts of Toulouse played a crucial role in the political and cultural development of the region, often engaging in alliances and conflicts with neighboring territories. One of the most notable Counts was Raymond IV, who participated in the First Crusade in the late 11th century. The count's influence extended beyond military endeavors, as he also contributed to the spread of Catharism and the development of the local economy. The title eventually became part of the larger Duchy of Aquitaine.
