The Burgundian party was a political allegiance against France that formed during the latter half of the Hundred Years' War. The term "Burgundians" refers to the supporters of the Duke of Burgundy, John the Fearless, that formed after the assassination of Louis I, Duke of Orléans. Their opposition to the Armagnac party, the supporters of Charles, Duke of Orléans, led to a civil war in the early 15th Century, itself part of the larger Hundred Years' War.
