The last years of Otto’s reign were full of triumph. Secure in the obedience of the Church, he ruled both Germany and Italy with an ever-increasing authority. The Magdeburg archbishopric received new suffragans in the sees of Zeiz, Meissen, and Merseburg. A new era of peace and prosperity dawned. The German dukes were afraid to resist so mighty a power. The division of Lotharingia into the two duchies of Upper and Lower Lorraine which now took place was the first step in the gradual process that soon began to undermine the unity of the traditional ‘nations’ of the German people. Beyond his Teutonic kingdom the kings of the barbarous north and east paid Otto an increasing obedience. The marauding heathens of an earlier generation were now becoming settled cultivators of the soil, Christian and civilised. Their dukes looked up to Otto as an exemplar of the policy which they themselves aspired to realise. The dukes of Poland and Bohemia performed homage to Otto as Emperor. Ambassadors from distant lands, France, Denmark, Hungary, Russia, and Bulgaria, flocked around his throne. He intervened with powerful effect in the West Frankish kingdom. He aspired to the domination of southern Italy, and, having won over to his side the powerful Pandulf, prince of Capua and Benevento, he enlarged that prince’s dominions and erected them into a mark to withstand the assaults of the Arabs and Greeks of southern Italy. But while waging war against the Mohammedans, Otto was anxious to be on good terms with the Romans of the East. The accession of John Zimisces to the Eastern Empire [see pages 161–162] gave Otto his opportunity. The new lord of Constantinople offered the hand of Theophano, daughter of his predecessor Romanus II., as the bride of the young Otto II., with Greek Italy as her marriage portion. [Sidenote: Marriage of the young Otto and Theophano, 972.] The Emperor welcomed the opportunity to win peacefully what he had sought in vain to acquire by war. Early in 972 Theophano was crowned by John XIII. at Rome, and immediately afterwards married to the young Emperor. The gorgeous festivities that attended this union of East and West brought clearly before the world the reality of Otto’s power.
