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.
History of the Netherlands
In the 9th and 10th centuries, the Vikings raided the largely defenceless Frisian and Frankish towns lying on the coast and along the rivers of the Low Countries. Although Vikings never settled in large numbers in those areas, they did set up long-term bases and were even acknowledged as lords in a few cases. In Dutch and Frisian historical tradition, the trading centre of Dorestad declined after Viking raids from 834 to 863; however, since no convincing Viking archaeological evidence has been found at the site (as of 2007), doubts about this have grown in recent years.
