 However, it was not until the 12th century and the reigns of Louis VI (1108–1137) and Louis VII of France (1137–1180) that Paris became the principal residence of the kings, and the term Palais de la Cité (or "Royal Palace") was commonly used.Philip II (1180–1223) placed the royal archives, the treasury and courts within the royal palace, and thereafter the city functioned, except for brief periods, as the capital of the kingdom of France.Louis IX, or Saint Louis, the grandson of Philip II, gave the palace a new symbol that combined royal and religious symbolism.
