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.

Viking raiders attacked wealthy targets on the north-western coasts of Europe from the late 8th until the mid-11th century CE. Pre-Christian traders and sea raiders, the Vikings first enter recorded history with their attack on the Christian monastic community on Lindisfarne Island in 793.
