These five titles were ranked from high to low, representing different fiefs and social status. According to the records, a duke was the highest rank of nobility, and his fief was five hundred miles. Marquises ranked second, with military strength and a good reputation. Earls were ranked third, and their national strength was relatively small. Viscount and baron were the titles of nobles.
