North Germanic peoples
Vikings were also active in Francia. Some of these Vikings would sail through the Strait of Gibraltar and pillage the coasts of the Mediterranean Sea. In the early 10th century, a group of Vikings under the leadership of Rollo settled in Rouen, France, and established the Duchy of Normandy. The descendants of these Vikings, known as the "Normans", would in the 11th century conquer England, Southern Italy, and North Africa, and play a leading role in launching the Crusades. Sub-groups of the Normans include Anglo-Normans, Scoto-Normans, Cambro-Normans, Hiberno-Normans and Italo-Normans.
Vikings
Anglo-Scandinavian is an academic term referring to the people, and archaeological and historical periods during the 8th to 13th centuries in which there was migration to—and occupation of—the British Isles by Scandinavian peoples generally known in English as Vikings. It is used in distinction from Anglo-Saxon. Similar terms exist for other areas, such as Hiberno-Norse for Ireland and Scotland.
