The Capetian Dynasty was a royal family that ruled France from 987 to 1328. It began with Hugh Capet, who became king after the last Carolingian monarch. The dynasty is known for establishing a strong centralized monarchy and expanding the French territory through strategic marriages and alliances. Over the years, the Capetian Dynasty produced several notable kings, including Louis IX, also known as Saint Louis, who was revered for his piety and justice. The dynasty eventually split into several branches, including the Valois and Bourbon families, which continued to influence French history for centuries.
