Normandy
Normandy (French: Normandie) is an administrative region in northwestern France, consisting of the departments of Calvados, Eure, Manche, Orne, and Seine-Maritime, covering 29,907 square kilometers with a population of 3,339,074 in 2022.[1][2] The region emerged from Viking (Norsemen) settlements along the Seine River valley starting in the early 9th century, culminating in the establishment of the Duchy of Normandy in 911 when the Viking leader Rollo received territorial grants from the West Frankish king Charles the Simple via the Treaty of Saint-Clair-sur-Epte, marking the formal assimilation of Norse settlers into Frankish feudal structures.[3][4] Under Duke William II (later William the Conqueror), Normandy launched the successful invasion of England in 1066, defeating King Harold Godwinson at the Battle of Hastings and initiating the Norman Conquest, which profoundly reshaped English governance, language, and society through the imposition of feudalism and Norman aristocracy.[5][6] In modern history, Normandy's coastline hosted the Allied amphibious landings of Operation Overlord on June 6, 1944—known as D-Day—the largest seaborne invasion in history, involving over 156,000 troops and enabling the liberation of Western Europe from Nazi occupation after nearly three months of intense combat.[7][8] Today, Normandy is renowned for its bocage hedgerow landscapes, dairy farming producing cheeses like Camembert and Livarot, cider and calvados production, and cultural landmarks such as Mont Saint-Michel abbey and the Bayeux Tapestry depicting the Conquest, drawing millions of tourists annually while maintaining a strong agricultural economy.[9][10]
