of fortification in Byzantine Asia, for which he was praised by Byzantine historian Niketas Choniates, is largely regarded as an important success. Manuel demanded tribute from the Turkmen of the Anatolian interior for the winter pasture in Imperial territory; he also improved the defenses of many cities and towns, and established new garrisons and fortresses across the region. As a result of the cumulative efforts of all three Komnenian emperors, Manuel's domination of Asia Minor was more effective than that of any emperor since before Manzikert. As historian Paul Magdalino makes clear, "by the end of Manuel's reign, the Byzantines controlled all the rich agricultural lowlands of the peninsula, leaving only the less hospitable mountain and plateau areas to the Turks." In the religious sphere, disputes between the Roman Catholic Church and the Eastern Orthodox Church occasionally harmed efforts at cooperation with the Latins; however, Manuel was almost certainly the Byzantine emperor who came closest to healing the breach between the two churches. Pope Innocent III clearly had a positive view of Manuel when he told Alexios III that he should imitate "your outstanding predecessor of famous memory the emperor Manuel... in devotion to the Apostolic See, both in words and in works". Manuel was very successful in expanding his influence, particularly over the Crusader states. As an example, he participated in the building and decorating of many of the basilicas and Greek monasteries in the Holy Land, including the Church of the Holy Sepulchre in Jerusalem where due to his efforts the Byzantine clergy were allowed to perform the Greek liturgy each day. All this reinforced his position as overlord of the Crusader states, with his hegemony over Antioch and Jerusalem secured by agreement with Raynald, Prince of Antioch, and Amalric, King of Jerusalem. This success in gaining influence and allies among the western states and the Pope is regarded one of the most impressive achievements of Manuel Komnenos's reign. Military reform At the beginning of the Komnenian period in 1081, the Byzantine Empire had been reduced to the smallest territorial extent in its history. Surrounded by enemies, and financially ruined by a long period of civil war, the empire's prospects had looked grim. Yet, through a combination of determination, military reform, and years of campaigning, Alexios I Komnenos, John II Komnenos and Manuel I Komnenos managed to restore the power of the Byzantine Empire.
