Other bands of these Northmen (Danes and Norwegians) began to prey on the northern coast of Frankland, and in the tenth century seized all the coast of what is now northern France and down as far as Paris and Tours. From Tours to Corbie (see Figure 41) churches and monasteries were pillaged and burned, Tours and Corbie with their libraries both perishing. Amiens and Paris were laid siege to, and disorder reigned throughout northern Frankland. _The Annals of Xanten_ and the _Annals of Saint Vaast_, two mediaeval chronicles of importance, give gloomy pictures of this period. Three selections will illustrate: According to their custom the Northmen plundered East and West Frisia and burned ... towns.... With their boats filled with immense booty, including both men and goods, they returned to their own country. [19] The Normans inflicted much harm in Frisia and about the Rhine. A mighty army of them collected by the river Elbe against the Saxons, and some of the Saxon towns were besieged, others burned, and most terribly did they oppress the Christians. [20] The Northmen ceased not to take Christian people captive and kill them, and to destroy churches and houses and burn villages. Through all the streets lay bodies of the clergy, of laymen, nobles, and others, of women, children, and suckling babes. There was no road or place where the dead did not lie, and all who saw Christian people slaughtered were filled with sorrow and despair. [21] After much destruction, Rollo, Duke of the Normans, finally accepted Christianity, in 912, and agreed to settle down in what has ever since been known as _Normandy_. From here portions of the invaders afterward passed over to England in the Norman Conquest of 1066. This was the last of the great German tribes to move, and after they had raided and plundered and settled down and accepted Christianity, western Europe, after six centuries of bloodshed and pillage and turmoil and disorder, was at last ready to begin in earnest the building-up of a new civilization and the restoration of the old learning.
