With Germany it was different. As the Merwing kingdoms decayed, the Eastern one, Austrasia, with its capital, Metz, was but a poor bulwark against heathen tribes on its borders, which were yet, it might seem at times, little more barbarous than itself. The kingdom of Austrasia stretched eastwards from Rheims "spreading across the Rhine an unknown distance into Germany, claiming the allegiance of Thuringians, Alamanni and Bavarians, fitfully controlling the restless Saxons, touching with warlike weapons and sometimes vainly striving with the terrible Avars." [1] Kings of the Bavarian line came to rule in Northern Italy, but Bavaria was little touched by Christian faith. At last when the descendants of Arnulf[2] came as kings over a now again united Frankish monarchy, when Charles Martel made one power of Austrasia, Neustria, and Burgundy, the time for a new advance seemed to have come. Theodelind, the Catholic queen of the Lombards, was herself of Bavarian birth, but a century after her time the people of her native land, it seems, were still heathen. They were apart from the Roman civilisation and the Catholic tradition: conversion, to touch them, must be a direct and aggressive movement. At the end of the seventh century S. Rupert began the work. He settled his episcopal throne at Salzburg. He was followed by Emmeran, and by Corbinian. Slowly the work proceeded, hindered by violence on the part of dukes and saints, favoured by popes and making a beginning for Roman missionary interest in the distant borders of the Empire under the Germans. {136} But it was not to these Frankish missionaries, or to Roman envoys, that the most important work was due. It was due to an outburst of converting zeal on the part of the newly converted race who had made Britain the land of the English. [Sidenote: Saint Boniface.]
