The Carolingian dynasty ruled France until 987, when Hugh Capet, Duke of France and Count of Paris, was crowned King of the Franks. His descendantsthe Capetians, the House of Valois and the House of Bourbonprogressively unified the country through wars and dynastic inheritance into the Kingdom of France, which was fully declared in 1190 by Philip II of France (''Philippe Auguste''). Later kings would expand their directly possessed ''domaine royal'' to cover over half of modern continental France by the 15th century, including most of the north, centre and west of France. During this process, the royal authority became more and more assertive, centered on a hierarchically conceived society distinguishing nobility, clergy, and commoners.
