The Capetians made Paris their principal seat: the royal domain (the estate of land, rights and taxes which were in the hands of the king) extended around Paris. From the 12th century onwards, the kings of France came to restore their power over the whole of France. Because of invasions, a multitude of local lords developed to be able to defend the country at a local level. The kings restored their power over France by using Paris and its region as the hub of power. The French court remained itinerant throughout the Middle Ages. The king went from estate to estate to hunt or to make war, but the birth of the State was accompanied by the development of a central administration in Paris. Some key points of this development were: - In 1146 King Louis VII established his treasury in Paris while he was away on Crusade. From then on the royal treasure remained in Paris. - In 1194, at the battle of Freteval, King Philippe-Auguste was robbed of his archives by the English. The archives after that were kept in Paris.
