The House of Capet was a royal dynasty that ruled France from 987 to 1328. Founded by Hugh Capet, it marked the beginning of the Capetian dynasty, which became one of the most influential royal families in European history. The Capetians expanded their territory and strengthened the monarchy, establishing a centralized state. Over the centuries, the House of Capet produced several notable kings, including Louis IX and Philip IV. The dynasty's influence extended beyond France, as it intermarried with other royal families across Europe. The Capetian legacy continues to shape the history of France and its monarchy.
