Encyclopædia Britannica, Ninth Edition/Île-de-France

ÎLE-DE-FRANCE, an old district of France, forming a kind of island, bounded by the Marne, the Seine, the Oise, the Aisne, and the Ourcq. Until the end of the Carlovingian dynasty it was included in the domains of the crown. The government of Île-de-France, named after this district, now embraces the department of the Seine, together with the greater part of Seine-et-Oise, Seine-et-Marne, Oise, and Aisne, and a small part of Loiret and Nievre. It was bounded on the N. by Picardy, on the W. by Normandy, on the S. by Orleannais and Nivernais, and on the E. by Champagne. Its capital was Paris.
