Why did the byzantines saved their city from the invasions and the greek’s classic?

Shortly after the extended controversy over iconoclasm, which more or less ended (at least in the east) with the regent Theodora reinstating icon worship in 842 CE, Emperor Basil I founded a new dynasty, the Macedonian Dynasty, in 867 CE. Basil was born a simple peasant in the Byzantine theme of Macedonia; he rose in the Imperial Court, and usurped the imperial throne from Emperor Michael III (r. 842-867). Despite his humble origins, he showed great ability in running the affairs of state, leading to a revival of imperial power and a renaissance of Byzantine art. He was perceived by the Byzantines as one of their greatest emperors, and the Macedonian Dynasty ruled over what is regarded as the most glorious and prosperous era of the Byzantine Empire.
