The twenty years that followed the return to Constantinople were absorbed in the work of restoring the Empire and adjusting the quarrels of the partisans of the rival patriarchs. Of the restoration it is enough to say that, as in all similar efforts during the last three centuries of the Empire, it consisted in recovering the revenue of the Court and enriching the Emperor’s supporters, not in any serious attempt to revive the industries and commerce of the Empire.[34] Nor were Michael’s attempts to make foreign alliances much more successful. Foiled in his efforts to secure the interest of Latin rulers, he turned to the Servians and Bulgarians. In 1272 he decided that his second daughter, Anna, should marry the King of Servia. Theodora had some misgiving that the barbaric Servians were unfit to receive her daughter, and she directed the ministers who took Anna to the frontier to send on in advance a party to explore the Servian Court, and to linger sufficiently on the journey to receive their report. It proved a wise precaution. The Servians had gathered round the advance party like--as described in the Byzantine chronicles--a group of savages. Anna’s eunuchs excited their intense curiosity, though not their admiration, and the superb equipment of the princess was heatedly criticized. They brought out Anna’s prospective mother-in-law, a dirty and coarsely dressed woman, to show the Greeks a model queen. They also stole the imperial horses. So the advance party hastily sent a report to the ministers who lingered on the way with Anna and she was conducted back to her mother. In the same year Eulogia’s daughter Maria was married to the King of Bulgaria, but the marriage brought little profit to the Emperor. Eulogia had now quarrelled with Michael. She took the part of the ex-patriarch Germanus, and she and her daughters and her favourite monks threw themselves so ardently into the religious quarrel, which the Emperor vainly endeavoured to settle, that Michael was very angry with them. Monks now travelled constantly between the young Queen of Bulgaria and the Empress-nun, her mother, and gravely disturbed Michael’s work. After a time Maria sent some of the monks to Palestine to induce the Sultan to harass her uncle’s territory, and she even persuaded her husband to declare war on him. Michael hated the monks as heartily as Eulogia loved them, and he at length expelled his sister from the capital. When he went on to propose a union of the Latin and Greek Churches, and induced a synod at Constantinople to acknowledge the supremacy of the Pope, Eulogia’s love was turned into violent hatred of the Emperor.
