The Viking Age approximately lasted from 790 to 1066 A.D. During this period, Vikings left their Scandinavian homelands and ranged far and wide in Western Europe.
They expanded their influence through warfare and built settlements throughout the Europe, Central Asia and England. Scandinavian Norsemen explored many new lands for raids, colonization and conquest. They left a permanent and very strong impact on the lands they ruled and governed.
The reason behind the Viking attacks in the early history was for finding secure trade routes because like other countries, they needed to sell their goods to earn money and buy new things for their need. But with time they started looting isolated lands and town for gold.
They started with coastal lands especially the monasteries that were undefended. They killed the priests and collected the booty leaving everything destroyed in their way.
Another big reason to move and raid for new lands was the climate changes, population pressure and harsh winters in their original homelands that forced them to seek land and resources elsewhere.
In A.D. 793, the first Viking raid took place against the Lindisfarne monastery on the coast of England. The attacked shocked the Europeans and Christians all around Europe.
As compared to other pirates and attackers, this new group had no rules and no respect for religious institutions.
After some years, the Vikings raided the undefended island monasteries of Skye and Iona in 799. In the subsequences years, they continued to attack many isolated lands along the coastal lands in Britain and Europe.
Building on these raids, they began to establish permanent settlements. They took advantage of the internal dispute and conflicts in Europe and England to extend their lands. With time, the Vikings adopted Christianity and settled in France, Italy and England.
The English coastal lands and monasteries were the first target of the Viking raiders. By the mid-eighth century England, Ireland and Scotland had become the main targets of Viking raiders.
They gained control of much of the Scotland and founded the first trade center in Dublin, Ireland. Then they launched attacks on England across the Irish Sea.
After 851, the repeated waves of Viking attacks in England left only one original Anglo-Saxon kingdom intact – Wessex. Many of the Vikings settled in England as traders and farmers and established a new city called York.
In time, a permanent section of England called Danelaw became home to Vikings.
The Vikings were attracted by the wealth of their neighbors with whom they often traded during the 8th and 9th centuries. They began to venture to France in long Viking boats and raid the coastal lands.
In 845, the Viking ventured as far as Paris, laid siege to Paris and then sacked the city. Over time, Vikings established permanent settlements in modern-day Normandy.
To end the threat of Viking invasions, King Charles III of West France conceded the lands as the Duchy of Normandy to Roll, a famous Viking leader.
