A new Greek nation had in fact come into being, and it found itself in touch with new neighbours, whom the Ancient Greek had never known. Eastward lay the Armenians, reviving, like the Greeks, after the ebb of the Arab flood, and the Arabs themselves, quiescent within their natural bounds and transfusing the wisdom of Aristotle and Hippokrates into their native culture. Both these peoples were sundered from the Orthodox Greek by religion[1] as well as by language, but a number of nationalities established on his opposite flank had been evangelized from Constantinople and followed the Orthodox patriarch in his schism with Rome. The most important neighbour of the Empire in this quarter was the Bulgarian kingdom, which covered all the Balkan hinterland from the Danube and the Black Sea to the barrier-fortresses of Adrianople and Salonika. It had been founded by a conquering caste of non-Slavonic nomads from the trans-Danubian steppes, but these were completely absorbed in the Slavonic population which they had endowed with their name and had preserved by political consolidation from the fate of their brethren further south. This Bulgarian state included a large ‘Vlach’ element descended from those Latin-speaking provincials whom the Slavs had pushed before them in their original migration; while the main body of the ‘Rumans’, whom the same thrust of invasion had driven leftwards across the Danube, had established itself in the mountains of Transylvania, and was just beginning to push down into the Wallachian and Moldavian plains. Like the Bulgars, this Romance population had chosen the Orthodox creed, and so had the purely Slavonic Serbs, who had replaced the Rumans in the basin of the Morava and the Bosnian hills, as far westward as the Adriatic coast. Beyond, the heathen Magyars had pressed into the Danubian plains like a wedge, and cut off the Orthodox world from the Latin-Teutonic Christendom of the west; but it looked as though the two divisions of Europe were embarked upon the same course of development. Both were evolving a system of strongly-knit nationalities, neither wholly interdependent nor wholly self-sufficient, but linked together in their individual growth by the ties of common culture and religion. In both the darkness was passing. The future of civilization seemed once more assured, and in the Orthodox world the new Greek nation seemed destined to play the leading part. [Footnote 1: The Armenians split off from the Catholic Church four centuries before the schism between the Roman and Orthodox sections of the latter.]
