BIOGRAPHY: In the early 880s, his brother, BOSON, king of Provence, made him count of Autun. By 890, Richard, who, by then, was known by his nickname, "The Justiciar" was also master of Sens, Auxerre, and Troyes. This was the Frankish portion of the ancient kingdom of Burgundy and was destined to become the Duchy of Burgundy under the Capetian kings of France.
