Viking raid warfare and tactics
Vikings were members of tribes, originally from Scandinavia, of Norse ancestry, who gained a reputation for their raids and piracy in many parts of Europe, especially England, Ireland, and Frankish territories. The term "Viking Age" refers to the period roughly from 793 AD to the late 11th century in Europe. In this era Viking activity started with raids on Christian lands in England and eventually expanded to mainland Europe, including parts of present-day Russia. While maritime battles were rare, Viking bands proved very successful in raiding coastal towns and monasteries due to their efficient warships, and intimidating war tactics, skillful hand-to-hand combat, and fearlessness. What started as Viking raids on small towns transformed into the establishment of important agricultural spaces and commercial trading-hubs across Europe through rudimentary colonization. Vikings' tactics in warfare gave them an enormous advantage in successfully raiding (and later colonizing), despite their small population in comparison to that of their enemies.
Viking Age
The end of the Viking Age is traditionally marked in England by the failed invasion attempted by the Norwegian king Harald III (Haraldr Harðráði), who was defeated by Saxon King Harold Godwinson in 1066 at the Battle of Stamford Bridge; in Ireland, the capture of Dublin by Strongbow and his Hiberno-Norman forces in 1171; and 1263 in Scotland by the defeat of King Hákon Hákonarson at the Battle of Largs by troops loyal to Alexander III. Godwinson was subsequently defeated within a month by another Viking descendant, William, Duke of Normandy. Scotland took its present form when it regained territory from the Norse between the 13th and the 15th centuries; the Western Isles and the Isle of Man remained under Scandinavian authority until 1266. Orkney and Shetland belonged to the king of Norway as late as 1469.
