History tells us but little more of Charles. He carried his arms into the Netherlands, conquered the Frisians and other tribes which then dwelt there, made them Christians by force, and vassals of the Frankish crown. In Saxony, and other parts of Germany also, his power was feared and obeyed. Pope Gregory II. offered to transfer to him the allegiance due from Rome to the Greek emperor, but the scheme was ended by the death of Charles. After the decease of King Chilperic II., in 720, Thierry IV. reigned in the same feeble manner as the other kings of his degenerate race. On his death, in 736, the people did not care to appoint a successor, being satisfied with the government which Charles continued to exercise under the title of "Duke of the Franks." He died in 741, at the age of forty-seven, leaving the monarchy to his three sons, Pepin, Carloman, and Griffo. Of the elder of these, we shall hear more anon. Charles Martel is the first hero who succeeded in stamping his image upon the surface of European history, after the chaos of the broken Roman empire had in some measure yielded to the spirit of order. He was chieftain of an unruly tribe, rather than king of a settled state. In this light we must regard him if we would judge his character fairly; and thus considered, he may be said to have governed France wisely and well. If his memory cannot be cleared from the reproach of certain deeds of violence, we can afford to pardon him when we remember the good service that his strong hammer once wrought for Europe.
Charles Martel, as we have seen, was never king of the Franks, and his sons were too politic to assume the title on his death. Griffo, the third son, may be dismissed from our notice at once, as he was from the government of the kingdom, his brothers, Carloman and Pepin, taking advantage of his weakness to dispossess him. After this act of supremacy they were for some time content to act as Mayors of the Palace, in the districts of Neustria and Austrasia respectively, under the nominal sovereignty of Childeric III., the last of the _fainéant_ kings, whom they set up as a puppet. Carloman distinguished himself by attacking the Saxons and other tribes which threatened aggression; and in 744 Pepin severely punished a revolt of his father's old enemy (Eudes, Duke of Aquitaine), who, as already stated, had been compelled to do homage to the Frankish crown. Pepin soon had no sharer in his power or fame. Carloman was not made for a soldier, and, under the sudden impulse of devotional feeling, resigned his office in 747, and retired into a Roman monastery.
