هنري الثاني ملك إنجلترا
Henry II of England continued to stoke revolts and rebellions in Brittany against Conan IV. In response, Conan IV took the Breton counties of Tréguier and Guingamp from his uncle Count Henri, a supporter of Henry II of England. Richmond was returned to Conan IV later that year in an agreement reached with Henry II of England.
