And so the Popes, who were not only very holy but also very practical, cast about for a friend, and presently they made overtures to the most promising of the Germanic tribes who had occupied north-western Europe after the fall of Rome. They were called the Franks. One of their earliest kings, called Merovech, had helped the Romans in the battle of the Catalaunian fields in the year 451 when they defeated the Huns. His descendants, the Merovingians, had continued to take little bits of imperial territory until the year 486 when king Clovis (the old French word for "Louis") felt himself strong enough to beat the Romans in the open. But his descendants were weak men who left the affairs of state to their Prime minister, the "Major Domus" or Master of the Palace. Pepin the Short, the son of the famous Charles Martel, who succeeded his father as Master of the Palace, hardly knew how to handle the situation. His royal master was a devout theologian, without any interest in politics. Pepin asked the Pope for advice. The Pope who was a practical person answered that the "power in the state belonged to him who was actually possessed of it." Pepin took the hint. He persuaded Childeric, the last of the Merovingians to become a monk and then made himself king with the approval of the other Germanic chieftains. But this did not satisfy the shrewd Pepin. He wanted to be something more than a barbarian chieftain. He staged an elaborate ceremony at which Boniface, the great missionary of the European northwest, anointed him and made him a "King by the grace of God." It was easy to slip those words, "Del gratia," into the coronation service. It took almost fifteen hundred years to get them out again. Pepin was sincerely grateful for this kindness on the part of the church. He made two expeditions to Italy to defend the Pope against his enemies. He took Ravenna and several other cities away from the Longobards and presented them to His Holiness, who incorporated these new domains into the so-called Papal State, which remained an independent country until half a century ago. After Pepin's death, the relations between Rome and Aix-la-Chapelle or Nymwegen or Ingelheim, (the Frankish Kings did not have one official residence, but travelled from place to place with all their ministers and court officers,) became more and more cordial. Finally the Pope and the King took a step which was to influence the history of Europe in a most profound way.
