The Capetian house of Valois (UKˈvælwɑː , also USvælˈwɑː,_vɑːlˈwɑː , valwa) was a cadet branch of the Capetian dynasty. They succeeded the House of Capet (or "Direct Capetians") to the French throne, and were the royal house of France from 1328 to 1589. Junior members of the family founded cadet branches in Orléans, Anjou, Burgundy, and Alençon.
The Valois descended from Charles, Count of Valois (1270–1325), the second surviving son of King Philip III of France (reigned 1270–1285). Their title to the throne was based on a precedent in 1316 (later retroactively attributed to the Merovingian Salic law) which excluded females (Joan II of Navarre), as well as male descendants through the distaff side (Edward III of England), from the succession to the French throne.
After holding the throne for several centuries the Valois male line became extinct and the House of Bourbon succeeded the Valois to the throne as the senior-surviving branch of the Capetian dynasty.
The Capetian dynasty seemed secure in the rule of the Kingdom of France both during and after the reign of King Philip IV (Philip the Fair, 1285 - 1313). Philip left three surviving sons (Louis, Philip and Charles) and a daughter (Isabella). Each son became king in turn, but each died young without surviving male heirs, leaving only daughters who could not inherit the throne. When Charles IV died in 1328 the French succession became more problematic.
In 1328 three candidates had a plausible claim to the French throne:
Philip, Count of Valois, son of Charles of Valois, who was the closest heir in male line and a grandson of Philip III ( 1270 - 1285). Because his father was the brother of the late Philip IV, the Count of Valois was therefore a nephew of Philip IV and the cousin of Louis X, Philip V and Charles IV. Further, Charles IV had chosen him as the regent before his death.
Joan of Navarre, daughter of Louis X. Although Philip V had used his position relative to his niece to take the throne in 1316, Joan nevertheless had a strong claim as the heir-general of Philip IV, and her maternal family had initially supported her claim after the death of Louis X.
