486—Clovis, king of the Franks, defeated the Romans and Gauls at the battle of Soissons. The Ostrogoths invaded 492—Italy under Theodoric the Great, deposed Odoacer, and founded a new kingdom. 496—Clovis defeated the invading Germans and embraced 500—Christianity. Clovis next defeated the Burgundians. 507—He subdued the Visigoths and all France was united under one rule. He was of the Merovingian line, or dynasty, of kings, which lasted over two hundred years, during which the remains of Roman civilization and the influence of the church were gradually modifying and penetrating the character of a new and energetic race. 527—Justinian became the ruler of the Eastern or Grecian Empire. 534—His generals waged war with the Vandals in Africa and the Ostrogoths in Italy, and after eighteen years of conflict, succeeded in reconquering part of Italy, which the Greek emperors continued to hold nominally for about three hundred years; the seat of their representative being at Ravenna. He was called an Exarch. Rome itself was left, substantially, to the control of the Christian bishop. When the Lombards founded a kingdom 568—in the north of Italy they were prevented, by the exarch and bishop, from spreading over the southern part; and when the exarch threatened to become too powerful to suit the views of the bishop, he supported the Lombards. Thus the temporal or political power of the popes arose, and they were the politic authors of the “Balance of Power” theory, or system, that has played so large a part in European history. The result has been exceedingly favorable to progress in all directions, since it has secured the independence of states, and a more various and perfect civilization by the development of the special genius of each people. Many circumstances conspired to support this idea, in later times, and render it very prominent and influential.
