The Normans (Norman: Normaunds; ; Old Norse: Norðmaðr) are an ethnic group that arose from contact between Norse Viking settlers of a region in France, named Normandy after them, and indigenous Franks and Gallo-Romans. The settlements in France followed a series of raids on the French coast mainly from Denmark — although some came from Norway and Iceland as well — and gained political legitimacy when the Viking leader Rollo agreed to swear fealty to King Charles III of West Francia following the Siege of Chartres in 911 AD. The intermingling of Norse settlers and native Franks and Gallo-Romans in Normandy produced an ethnic and cultural "Norman" identity in the first half of the 10th century, an identity which continued to evolve over the centuries. - Source: Wikipedia
