Note S — Chapter V · THE DEVELOPMENT OF THE FEUDAL STATE
John M. (John Milton) Gitterman translation
One of the most notable instances may be found in the case of Markward of Annweiler, Marquis of Ancona and Duke of Ravenna, seneschal of Henry VI., who after the death of the Emperor Henry VI. disputed the power of the Regent Constance acting for her son, Frederick II. (See Boehmer-Ficker, Regesta Imperii, V, vol. 1, No. 511. v. ad. annum 1197.)—Translator.
