Duchesse d'Orléans


The Orléans part of the title comes from the city of Orléans, which was the capital of these kings. The Frankish kings in that region stopped calling themselves Kings of Orléans after they conquered the Burgundians. After 613 the Kingdom of Orléans became the Kingdom of Burgundy, and the queens became Queen consorts of Burgundy.
