Louis rebelled against his father in 1440 as head of the "Praguerie". Despite this, he was forgiven. Louis gave him the management of an area of south-east France known as the Dauphiné. There, Louis led his own political establishment and married Charlotte of Savoy, daughter of Louis, Duke of Savoy. His father did not approve of the marriage and sent an army, but Louis fled to Burgundy, where he was hosted by Charles' biggest enemy Philip the Good, Duke of Burgundy.
