The Count of Rouen was a title held by the rulers of the region of Rouen in Normandy, France. This title emerged during the early medieval period, particularly as the area became significant in the context of the Viking invasions and subsequent settlements. The Counts played a crucial role in local governance and military leadership, often acting as intermediaries between the local population and the broader authority of the French crown. The title was closely associated with the Duchy of Normandy, which was established in the 10th century. Over time, the Counts of Rouen contributed to the development of the region, influencing its culture and politics. Notably, the title eventually became part of the larger title of the Duke of Normandy, especially after the Norman Conquest of England in 1066.
