That time was indeed the nadir of order and civilization. From all sides the torrent of barbarism which Charles the Great had stemmed was rushing down upon his empire. The Saracen wasted the Mediterranean coasts, and sacked Rome herself. The Dane and Norseman swept the Atlantic and the North Sea, pierced France and Germany by their rivers, burning, slaying, carrying off into captivity: pouring through the Straits of Gibraltar, they fell upon Provence and Italy. By land, while Wends and Czechs and Obotrites threw off the German yoke and threatened the borders, the wild Hungarian bands, pressing in from the steppes of the Caspian, dashed over Germany like the flying spray of a new wave of barbarism, and carried the terror of their battleaxes to the Apennines and the ocean. Under such strokes the already loosened fabric swiftly dissolved. No one thought of common defence or wide organization: the strong built castles, the weak became their bondsmen, or took shelter under the cowl: the governor--count, abbot, or bishop--tightened his grasp, turned a delegated into an independent, a personal into a territorial authority, and hardly owned a distant and feeble suzerain. The grand vision of a universal Christian empire was utterly lost in the isolation, the antagonism, the increasing localization of all powers: it might seem to have been but a passing gleam from an older and better world.

When the male line of the eastern branch of the Carolingians had ended in Lewis (surnamed the Child), son of Arnulf, the chieftains chose and the people accepted Conrad the Franconian, and after him Henry the Saxon duke, both representing the female line of Charles. Henry laid the foundations of a firm monarchy, driving back the Magyars and Wends, recovering Lotharingia, founding towns to be centres of orderly life and strongholds against Hungarian irruptions. He had meant to claim at Rome his kingdom's rights, rights which Conrad's weakness had at least asserted by the demand of tribute; but death overtook him, and the plan was left to be fulfilled by Otto his son.
