Henry the Fowler, elected after nineteen years of nominal kingship and unbridled anarchy, defined his position by a series of compacts with the great Dukes. Suabia, Bavaria and Lotharingia became dependent principalities, whose rulers attended national Diets, occasionally appeared at court, and still more occasionally rendered military service. Under their sway the new feudalism, which they encouraged as the means of creating armies both for defence and for pursuing an independent foreign policy, took root and throve as a legal institution. Within the borders of the duchies Henry had little power except as the patron of the church. He claimed the right of nominating bishops--though in Bavaria this claim was not made good till the next reign--and religious foundations held their privileges by his grace. The ecclesiastical councils which legislated with his sanction were more important than the Diets composed indifferently of laymen and prelates. His general policy gave greater cause for satisfaction to the clergy than to the remainder of his subjects. The assertion of supremacy over Lotharingia (925), and Bohemia (929), and the defeat of the Hungarians at the Unstrut (933), were national achievements; but for nine years before the battle of the Unstrut the King had allowed the Hungarians to work their will in Bavaria and Suabia, having secured the immunity of his own duchy by a separate truce. He had chiefly employed those years in building strong towns for the defence of Saxony, and in extending Saxon power by the conquest of Brandenburg, Lusatia, Strelitz and Schleswig. These could only be called national services on the assumption that the crown was to remain the hereditary possession of his house; but the German kingship was elective. To the Church, however, nothing was more welcome than conquests gained at the expense of heathen Slavs and Danes. In her eyes this Saxon statesman was the forerunner of the Christian faith in the dark places of Europe. For all these reasons, then, the power of Henry and his successors remained a power resting upon ecclesiastical support. To strengthen the alliance of church and state must be the first object of a Saxon ruler.
