Louis XIV's will gave power to his illegitimate son, and the Paris Parlement annulled it the day after he died

Louis XIV outlived his son and grandson. His heir was his five-year-old great-grandson, Louis XV. In 1714 he issued an edict making his sons by Madame de Montespan, the Duke of Maine and the Count of Toulouse, eligible to inherit the throne if the legitimate line died out. His will, deposited with the Parlement of Paris, named his nephew Philippe d'Orléans head of a regency council but bound him to majority votes, and gave Maine custody of the boy king and command of the household troops. Louis died on 1 September 1715. On 2 September Orléans went to the Parlement and had the will set aside, taking full powers as regent. In return he restored the Parlement's right to object to royal laws. In 1717 the legitimised sons lost their right to the throne, and in 1718 Maine was stripped of custody of the king. Maine's wife then joined a plot with Spain against the regent and was arrested^†.
