3. The kings of the Franks—the German nation that conquered Gaul—up to the time of Charlemagne, labored to consolidate their power and rule like the Roman emperors. But the genius of their race and the peculiarities of the situation were both opposed to that purpose. Charles Martel, Pepin, his son, and Charlemagne, his grandson, were all rulers of great vigor, and the last, apparently, succeeded for a time. But the military strength lay only in the scattered feudal chieftains, each of whom sought to build up his own power on his own estates. It was not possible to maintain a strong central government for any length of time, or under an ordinary man. For two hundred years these petty lords grew in strength at the expense of the king. They were still held to him by the necessity of supporting him in war, by a system of checks, which, in time, were increased, and still more enlarged, when the people began to make themselves felt in the twelfth century; but from the fifth to the fifteenth century feudalism was the prevailing system in all the civilized European nations. 4. It was a very rude and violent period, but some of the most happy traits of modern life grew out of it. The isolation of the feudal lord in his fortified chateau or castle, where his wife and children were his only equals, combined with the constant influence of the church, gradually elevated the condition of the woman, the rudeness and violence of the time were modified by the rise of chivalry, which was, in great part, founded on this new respect for the gentler sex, and sympathy for her helpless condition when exposed, without a powerful protector, to unrestrained insolence and passion; and the feudal system held all the elements of society in suspense until the mighty forces—revived learning, the printing press, and a new commerce and industry—were ready to take a prominent part in making it what we now find it—far superior to the old society.
