The term "Valois-Orléans" refers to a branch of the {House of Valois}, a royal family that ruled France during the late Middle Ages. This branch emerged from the union of the Valois dynasty and the {House of Orléans}, which was established by {Louis I, Duke of Orléans} in the early 15th century. The Valois-Orléans family played a significant role in French politics and history, particularly during the {Hundred Years' War}. The most notable member of the Valois-Orléans branch was {Charles, Duke of Orléans}, a poet and soldier who was captured during the war. His literary contributions and experiences in captivity helped shape French literature. The Valois-Orléans lineage continued to influence French nobility until the end of the {Ancien Régime} in the late 18th century.
