Early Scandinavian Dublin
In the year 795 Vikings (probably of Norwegian origin) raided islands off the coast of Ireland for the first time. This was the beginning of a new phase of Irish history, which saw many native communities – particularly ecclesiastical ones – relocate themselves on the continent, or further afield in places like Iceland and the Faroe Islands, to escape the pagan marauders. For about two decades the invaders confined their activities to coastal settlements; raiding parties were generally small and there is no evidence that any of them wintered in Ireland during this early phase of "hit-and-run" activity. Typically the Vikings would arrive at a settlement without warning, plunder what goods and people they could – the people were usually sold as slaves, though notable personages were often held for ransom – before retreating to their Scandinavian or British bases. This period lasted from 795 until 813, after which there occurred a hiatus of eight years.
It is now thought that these early raids were launched directly from southwest Norway, and that during the period of calm (814–820) the Norwegian Vikings were occupied in northern Britain, laying the foundations of a new kingdom referred to in Irish sources as Laithlind (later Lochlainn). Laithlind was once thought to be in Norway but it is now identified with Viking settlements in the British Isles, especially those in Scotland and the Isle of Man.
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.
