Byzantine Apogee: The Macedonian Emperors
For Byzantium, however, the ninth and tenth centuries represented a time of recovery and expansion. In the first place, the height of the Macedonian Renaissance took place in the later ninth and tenth centuries, resulting in a growth of learning among both clergy and lay elites. This growth of learning took place against the backdrop of military success by the emperors of the Macedonian Dynasty (867 – 1056). The first emperor of this dynasty, Basil I (r. 867 – 886), a soldier and servant of the emperor, had come from a peasant background. He seized control of the Empire when he murdered the reigning emperor and took the position for himself.
Basil was an effective emperor. To the east, as the Abbasid Caliphate broke down, he inflicted several defeats on the Arab emirs on the border, pushing the frontiers of the Empire further east. Although unsuccessful in fighting to maintain control of Sicily, he re-established Byzantine control over most of southern Italy.
It was under the Macedonian emperors that the Eastern Orthodox culture of the Byzantines spread north beyond the borders of the Empire. In 864, the Bulgar khan, whose predecessors had been building a state of their own, converted to Christianity and was baptized. This conversion allowed the Bulgar state to be legitimated by the Church in the same manner as had the Byzantine Empire and the kingdoms of Western Europe.
In the ninth century, Cyril and Methodius, missionaries from the city of Thessalonica, preached Orthodox Christianity to the Slavic peoples of Eastern Europe and devised the alphabet that we today call Cyrillic in order to write the Bible and liturgy in their own language, Slavonic. By bringing Orthodox Christianity to the Slavic peoples, the Byzantines brought them into the culture of the Byzantines.
Subsequent emperors maintained this record of successes. John Tzimisces (r. 969 – 976) established Byzantine control over most of Syria. Basil II (r. 976 – 1025) achieved further successes, crushing and annexing the Bulgar state that had grown up in the lands south of the Danube and further subordinating the Armenian kingdoms to the Byzantine emperor. By the end of his reign, the Byzantine territory encompassed about a fourth of what had been the Roman Empire at its height under Augustus. Basil II had further diplomatic triumphs. He allied with the princes of the Kievan Rus, a state that had grown up in Eastern Europe along the rivers between the Baltic Sea and the Black Sea. The Rus was a people group made up of a largely Slavic population, with rulers who were ethnically Norse and who had established themselves as rulers of both Slavic and Turkic subjects when they sailed down the rivers of Eastern Europe from their Scandinavian homeland. This was a hybrid culture already, combining Norse and Slavic. An alliance with the Byzantine Empire also brought Greek elements into the cultural mix. In 988, Kievan Grand Prince Vladimir (r. 980 – 1015) was baptized into the Christian religion and became a close ally of Basil II, sealing the alliance by marrying Basil’s sister, Anna. The elite culture of the Rus would come to reflect both Greek, Slavic, Norse, and also Turkic elements. Allying with these people had brought Basil II to the height of the Byzantine state’s power.
Despite its successes during the reign of the Macedonian emperors, the Byzantine state faced weaknesses. The theme system had gradually broken down. Increasingly, soldiers came not from the themes, but from the ranks of professional mercenaries, to include those made up of Norsemen. The soldiers of the themes received less training and served mainly as a militia that would back up the core of a professional army, known as the Tagmata. Whether this smaller tagmata would be up to the task of defending an empire the size of Byzantium would remain to be seen.
