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.
Medieval: Total War
The Creative Assembly announced the development of an expansion pack, "Medieval: Total War – Viking Invasion", on 7 January 2003. The "Viking Invasion" expansion pack adds a Viking campaign taking place from 793 to 1066, set upon an expanded map of the British Isles and western Scandinavia. The campaign replaces the original factions with earlier Anglo-Saxon and Celtic kingdoms such as Wessex, Mercia, Wales and Scotland, as well as the Vikings. The Viking faction is designed to raid the British Isles; to achieve this the faction has access to faster ships and gains money for every building destroyed upon the battle map. The Anglo-Saxon and Celtic factions have the goal of repelling the Vikings and ultimately controlling the British Isles. New historical units were included with the expansion pack, such as the huskarls. "Medieval: Total War: Viking Invasion" brought several enhancements that were also added to the original campaign: flaming ammunition giving the player an option to set alight enemy castles, and a pre-battle deployment screen, allowing the player to organise their forces and view the terrain and opposing forces before the battle begins. In addition, three new factions were added to the main "Medieval: Total War" campaign, along with ribauldequin artillery and the game's patch. The expansion pack was released on 7 May 2003 in the United States and on 9 May in the United Kingdom.
