As a result of the constant attacks by the Vikings and other nomads, the governments of Europe were constantly under attack. Communities did not feel that their governments were providing adequate protection for them against outsiders. The economies of Western Europe were in shambles, and trade routes were disrupted.
As the monarchs of central governments lost power, a new type of government evolved called Feudalism. Feudalism began in France around 900 A.D., and spread throughout the remainder of Europe within 150 years.
In the long run men hit only what they aim at.
Henry David Thoreau
The phrase ''it''s raining cats and dogs'' came from the fact that pets often hid in the roof of medieval homes to stay warm. During rainstorms they would sometimes slip off.
