At a battle with Richard I of England (Richard Coeur de Lion, Richard the Lion Heart) on the edge of the Fréteval forest (near Vendome) Philip II Augustus (Philippe Auguste) of France suffered a crushing defeat, and lost the treasure and the fiscal records that he carried on his campaigns. As a result Philippe Auguste was forced to reconstruct his records, and he decided to establish a greffe (registry) for his public acts. This project he entrusted to the monk Guerin. From 1195 official records were stored in the Trésor des Chartes.
In 1204 Philippe Auguste had the archive moved to the Louvre. At the end of the reign of St. Louis the Trésor des Chartes was moved to a building adjoining the Sainte-Chapelle within easy reach of the advocates of the palais. The archive grew as rapidly as the monarchy itself, and there was already a well-established archivist tradition in France by the fourteenth century.
