The first of these facts is the existence of a Slav race on the banks of the Dnieper in the seventh and eighth centuries, and the growth of cities and trade centres such as Kiev, Smolensk, and Novgorod, which seem already to have been considerable settlements when the earliest Russian records were written. Of these, from the point of view of literature, Kiev was the most important. Kiev on the Dnieper was the mother of Russian culture; Moscow and St. Petersburg became afterwards the heirs of Kiev.
Another factor of vital historical importance which had an indirect effect on the history of Russian literature was the coming of the Norsemen into Russia at the beginning of the ninth century. They came as armed merchants from Scandinavia; they founded and organized principalities; they took Novgorod and Kiev. The Scandinavian Viking became the Russian Kniaz, and the Varanger principality of Kiev became the kernel of the Russian State. In the course of time, the Norsemen became merged in the Slavs, but left traces of their origin in the Sagas, the Byliny, which spread from Kiev all over Russia, and still survive in some distant governments. Hence the Norse names Oleg (Helgi), Olga (Helga), Igor (Ingvar). The word Russian, Rus, the origin and etymology of which are shrouded in obscurity, was first applied to the men-at-arms who formed the higher class of society in the early Varanger states.
The next determining factor in the early history of Russian literature is the Church. Vladimir, Prince of Kiev, married the sister of the Emperor of Byzantium and was baptized; henceforward Christianity began to spread (987-8), but the momentous fact is that it was the Christianity of the East. The pearl of the Gospels, says Soloviev, was covered over with the dust of Byzantium, and Russia was committed to the Greek tradition, the Greek rivalry with the West and was consequently excluded from the civilization of the West and the great intellectual community of which Rome was the centre. This fact is of far-reaching and momentous importance. No less important was the introduction of the Slavonic liturgy, which was invented by two Greek brothers from Saloniki, in the ninth century, who tried to force their Macedonian dialect on all the Slavs, and succeeded in the case of Bulgaria and Servia. A century or so later it reached the Russian Slavs. Through Bulgaria, the Russians acquired a ready-made literature and a written language in a dialect which was partly Bulgarian and partly Macedonian, or rather Macedonian with Bulgarian modifications. The possession of a written language acted as a lever as far as culture was concerned. In the eleventh century, Kiev was one of the most enlightened cities in Europe.
