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
Led by the operas of German composer Richard Wagner, such as "Der Ring des Nibelungen", Vikings and the Romanticist Viking Revival have inspired many creative works. These have included novels directly based on historical events, such as Frans Gunnar Bengtsson's "The Long Ships" (which was also released as a 1963 film), and historical fantasies such as the film "The Vikings", Michael Crichton's "Eaters of the Dead" (movie version called "The 13th Warrior"), and the comedy film "Erik the Viking". The vampire Eric Northman, in the HBO TV series "True Blood", was a Viking prince before being turned into a vampire. Vikings appear in several books by the Danish American writer Poul Anderson, while British explorer, historian, and writer Tim Severin authored a trilogy of novels in 2005 about a young Viking adventurer Thorgils Leifsson, who travels around the world.
