obtained wealth by extortion, piracy, and plunder, and then distributed 
it to their followers. Where they could extort money without a fight, 
they did. Otherwise, they attacked in raids that were devastating and 
quick. During these raids, they took what they wanted and destroyed 
whatever was left. For three centuries, the Vikings terrorized the people 
of Ireland, Britain, France, Spain, and the Mediterranean. 
eir method was to attack with anything from several to dozens of 
longships, and dozens to hundreds of men. Viking longships snuck up 
on their targets, then they quickly closed in on their helpless victims.

e  British  Isles  and  western  Europe  were  studded  with  monas-
teries, and they were the raiders’ earliest targets. e monasteries had 
accumulated significant wealth in the form of gold and silver, cash, rit-

commodities, and luxury items.
In the mid-ninth  century, the Norse adopted two new strategies. 
Local kings began to pay the Norse to stay away. is protection money 
is known as tribute. e Vikings needed more than cash and gold, how-
ever.  Scandinavia’s  population was  outgrowing  its territory,  and they 
needed land. e second major strategic change was territorial expan-
sion. Instead of simply raiding, the Vikings began to conquer foreign 
kingdoms in order to establish their own settlements. By 1060, in fact, 
they had a kingdom in distant Sicily and southern Italy.

e British Isles were the Vikings’ earliest target. e Danes made their 
first attack on England in about a.d. 7
90 and continued these attacks 
for  the  next  two  centuries.  In  addition  to  its  mild  climate,  England 
offered rich farmland and opportunities for trade. In a.d. 8
65, between 
500  and  1,000  Vikings,  landed  on  the  east  coast.  Over  the  next  15 
years, they conquered the kingdoms of Northumbria, Mercia, and East 
Anglia. ey killed the English kings and set up their own chieftains
