Louis III, Count of Blois

Louis III of Châtillon, also known as Louis II of Blois-Châtillon, was count of Blois and Dunois from 1346 until his death. He also held the title count of Soissons until the county was ceded in connection with the ransom of his brother Guy II, who had been sent to England as a hostage after the Treaty of Brétigny.
