Basse-Normandie ('Lower Normandy') is an administrative region of France. It was created in 1956, when the Normandy region was divided into Basse-Normandie and Haute-Normandie (Upper Normandy). The region includes three departments, Calvados, Manche and Orne, that cover the part of Normandy traditionally termed "Lower Normandy" lying west of the Dives River, the Pays d'Auge (except a small part remaining in Haute-Normandie), a small part of the Pays d'Ouche (the main part remaining in Haute-Normandie), the Norman Perche and part of the "French" Perche. It covers 10,857 square miles, 3.2 percent of the surface area of France.
Traditional regions of Lower Normandy include the Cotentin Peninsula and La Hague, the Campagne de Caen, the Norman Bocage, the Bessin and the Avranchin.
The traditional province of Normandy, with an integral history reaching back to the 10th century, was divided in 1957 into two regions: Basse-Normandie and Haute-Normandie ("Upper Normandy").
During the Roman era, the region was divided into several different city-states. That of Vieux was excavated in the 17th century, revealing numerous structures and vestiges bearing testimony to the prosperity of the Caen region.
The region was conquered by the Franks in the 5th century.
In the 9th century, the Norman conquests devastated the region. Much of the territory of Lower Normandy was added to the Duchy of Normandy in the 10th century.
In 1066, William the Bastard conquered England, becoming William the Conqueror, or William I of England. He was buried in Caen.
The victory of Tinchebray in 1106 gave Normandy to the Plantagenets. Nearly one hundred years later, in 1204, Philippe Auguste confiscated the region. Then, during the Hundred Years' War, the region was annexed by England.
The French regained the region from 1436 to 1450. By 1468, it was entirely under the control of the French monarchy.
The main thrust of Operation Overlord during World War II was focused on Basse-Normandie. The beaches of Calvados were the site of the D-Day landings in June 1944. Basse-Normandie suffered badly during World War II, with many of the region's towns and villages being destroyed during the Battle of Normandy.
In terms of music, composer Erik Satie also hailed from this region. And in the visual arts, Jean-François Millet was a native of La Hague. Eugène Boudin was born in Honfleur and Fernand Léger in Argentan. Importants events include Deauville Asian Film Festival and Deauville American Film Festival.
