The Hungarians were still untamed, and, profiting by the civil war of 953, they now poured in overwhelming numbers into south Germany. But the common danger was met by common action. On 10th August 955, Otto won a decisive victory on the Lechfeld, near Augsburg, at the head of an army drawn equally from all parts of Germany, and including among its leaders Conrad the Red, the former Duke of Lorraine, who died in the fight. [Sidenote: The battle on the Lechfeld, 955.] This crushing defeat damped the waning energies of the Magyars, and the carrying out of the same policy against them that had been so successful against their northern neighbours resulted in the setting up of an east mark (the later Austria), which carried German civilisation far down the Danube, and effectually bridled the Magyars. In these regions Henry of Bavaria did the work that Hermann Billung and Gero were doing in the north. The final defeat of the barbarian marauders, and the wide extension of German territory through the marks, are among Otto’s greatest titles to fame. Moreover, Otto forced the rulers of more distant lands to acknowledge his sovereignty. In 950 he invaded Bohemia, and forced its duke, Boleslav, to do him homage. Nor did he neglect the affairs of the more settled regions of the west. Already in 946 he had marched through north France as far as the frontiers of Normandy, striking vigorous blows in favour of the Carolingian Louis IV.—who had married his sister Gerberga, Duke Giselbert’s widow—against his other son-in-law, Hugh the Great, the head of the rival Robertian house [see page 69]. He also took under his protection Conrad the Pacific, the young king of the Arelate.
