NORMANDY, an ancient province of France, bordering on the English Channel, now divided into the departments of Seine-Inferieure, Eure, Ome, Calvados, and Manche; anciently comprised a portion of the kingdom of Neustria, and was ceded to Rollo, Rolf, or Raoul, by Charles III., in 911. William I., Duke of Normandy, invaded England in 1066, and established a Norman dynasty, thereby uniting Normandy with the latter country. Philip Augustus conquered it in 1204, the French holding it till 1417, when it was recovered by the English, who held it till 1450, when it was finally wrested from them by Charles VII.
