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 metal
Viking metal features the Vikings as its subject matter and for evocative imagery. The Vikings were Northern European seafarers and adventurers who, during the Middle Ages, relied on sailing vessels such as longships, "knerrir", and "karvi" to explore, raid, pirate, trade, and settle along the North Atlantic, Baltic, Mediterranean, Black Sea, and Caspian coasts and Eastern European river systems. The Viking Age is generally cited as beginning in 793, when a Viking raid struck Lindisfarne, and concluding in 1066, with the death of Harald Hardrada and the Norman conquest of England. During this two-hundred-year period, the Vikings ventured west as far as Ireland and Iceland in the North Atlantic and Greenland and what is now Newfoundland in North America, south as far as the Kingdom of Nekor (Morocco), Italy, Sicily, and Constantinople in the Mediterranean, and southeast as far as what are now Belarus, Russia, and Ukraine in Eastern Europe, Georgia in the Caucasus, and Baghdad in the Middle East.
