Whether such a command over the atmospherical forces impressed the barbarian chiefs with the desirable qualities of so militant a religion, or whether the glories of the Tzargrad as seen dimly from their boats had insensibly attracted them to the worship of the “cold Christ and tangled trinities,” which was so much a part of the Byzantine life, it was said that Askold, shortly after the miscarriage of the expedition, professed the Christian faith. This much at least seems certain, that the Greek patriarch Photius was able in the year 866 to send to Kiev a priest with the title, if not the recognition of Bishop, and that from that time there existed a small Christian community in that town.
The Chronicle of Nestor, almost the only record of this period of Russian history in existence, is silent on two interesting points, namely, the works and fightings in which Rurik was presumably engaged on behalf of his infant state, and the attitude of the Khazars towards the adventurers who had filched Kiev and the adjoining territory from their authority.
The only further item in the Chronicle relating to Rurik is the announcement of his death in the year 879, his child son Igor and the governance of the country being entrusted to Oleg, a blood relation of the late Prince. The reign of this chieftain was of great importance to the fortunes of the germinating Russian State, and if Rurik played the part of a William the Bastard, Oleg may not unwarrantably be compared with Charles the Great. The rumours which had reached the North of a Varangian power that had sprung up among the tribes of the Slavic hinterland had attracted thither streams of roving warriors, eager to share the dangers and divide the fruits of their kinsfolks’ enterprise. Thus both Rurik and the Kievian adventurers had been able to maintain an easily-recruited standing force of their own countrymen for purposes offensive and defensive. The larger designs of Oleg, however, required a larger army, and he enlisted under his captaincy Slavs and Finns in addition to his Varangian guards. Having spent three years in gathering and perfecting his resources, he advanced in 882 into the basin-land of the Dniepr and moved upon Smolensk, the stronghold of the independent remnant of the Slav tribe of Krivitches. By virtue, possibly, of his position as leader of an army partly drawn from men of that tribe, he was allowed to take undisputed possession of the place, which was henceforth incorporated in the Russ dominion. Still following the course of the Dniepr, as Askold and Dir had followed it before him, he entered the country of the Sieverskie Slavs and made himself master of their head town, Lubetch.
By these successive steps Oleg had brought himself nigh upon Kiev, the headquarters of the rival principality, which was possibly the object he had had in view from the commencement of his southward march. For to the rising Russ-Slavonic State Kiev was at once a menace and an injury; not only did it offer an alternative attraction to the Norsemen pouring into the country, the natural reinforcements of Oleg’s following, but its separate existence cut short the expansion of the northern territory, and, above all, hindered free intercourse with Byzantium and the south. To the sea-rovers, reared among the rude and penurious lands that lay dark and uncivilised between the Baltic and the Arctic Sea, Byzantium was a dazzling and irresistible attraction; rich beyond their comprehension of riches, luxurious to a degree unknown to them, renowned for everything except renown, she seemed a golden harvest ripe for the steel of the valorous and enterprising. Between this desired land and the Novgorodian principality the territory of Askold presented a vexatious obstacle, and it was inevitable that the sagacity of Oleg should aim at its destruction. At the same time it was understandable that he should seek to avoid an armed conflict with his fellow-countrymen, the Varangians of Kiev, and to effect his purpose by stratagem rather than by force. To this end he approached the town, laid an ambuscade on the banks of the Dniepr, and in the guise of a trader travelling from Novgorod to Byzantium, sought speech with the Kievian rulers. Askold and Dir came out unwittingly to see this wayfarer, and found no man of wares and whining suppliance; found rather one whose face they well knew, and with him a small lad whose significance was swiftly made plain to them. “You are not of the blood of princes,” cried a voice of triumph and boding in their ears, “but here behold the son of Rurik.” And therewith rushed out the hidden ones and slew the unsuspecting chieftains. And in guerdon of this stroke Oleg was accepted as sovereign by the people of Kiev, the Russian State was solidified, and the supremacy of Rurik’s dynasty received a valuable recognition.
The town of Kiev, advantageously situated at a pleasant elevation above the west bank of the Dniepr, and commanding the waterway to the coveted south, compared favourably with Novgorod, built among the flat marshes that bordered Lake Ilmen and surrounded by the Finn-gripped coasts of Ladoga. The advantages of the former were not lost upon its conqueror, who saluted it with the title of “mother of all Russian cities” (so the Chronicles), and thenceforth it became the capital of the country. It was now necessary to secure the connection between the newly-won territory and the districts lying to the north. West and north of Kiev dwelt the Drevlians, a fierce and formidable Slavic tribe, whose country was fortified by natural defences of forest and marsh. Against them Oleg turned his arms, and once more victory went with him; the Drevlians, while retaining their own chieftain, were reduced to the standing of vassals, and an annual tribute of marten and sable skins was imposed upon them. Within the next two years the Russian ruler completed the subjugation of the Sieverskie and enthralled the remaining lands of the Krivitches, both of which tribes had hitherto owned allegiance to the Khazars. The growing Russian dominions were now put under a system of taxation, the sums levied being devoted in the first place to the payment of the Varangians in the Prince’s service. The contribution of Novgorod was assessed at the yearly value of 300 grivnas, a token of its substantial footing at this particular period.
It was about this time that the Ougres or Magyars, the ancestors of the modern Hungarians, squeezed out of their Asiatic home by the pressure of the Petchenigs, burst through the Khazar and Kievian territories and settled themselves in Moldavia and Wallachia, and finally in Hungary. Their passage through the Dniepr basin-land would scarcely have been undisputed, and the Magyar Chronicles speak of a victory over Oleg; the Russian chronicler is silent on the subject. This scurrying horde of nomad barbarians, unlike the Avars who preceded them, or the Petchenigs and Kumans who followed in their wake, crystallised in a marvellously short space of time into a civilised European State, and became an important neighbour of the Russian principality.
In 903 the young Igor was mated to a Varangian maiden named Olga, who, by one account, was born of humble parents in the town of Pskov and attracted the Prince by her beauty. Other accounts make her, with more probability, a near relative of the Regent, of whose strength of character she seems to have inherited a share.
In 907 Oleg was in a position to put into practice a project which had probably never been lost sight of, the invasion, namely, of the Byzantine Empire, including an attack on Constantinople itself, a project dear to the Russian mind in the tenth century as well as in later times. His footing differed essentially from that of Askold and Dir in their attempt at a like undertaking. No longer the leader of a mere troop of adventurers, Oleg swayed an army inspired by a long series of successes and confident in the sanction and prestige of the princely authority. Slavs, Finns, and Varangians were bonded together in a representative Russian army, trained, disciplined, and, above all, reliant on the ability of their captain. In their long, light barques they went down the Dniepr, hauling their craft overland where the rapids rendered navigation impossible, and thence emerged into the Black Sea; the boats were escorted along the river-banks by a large body of horsemen, but the Chronicle does not tell whether this branch of the expedition made its way through Bessarabia and Bulgaria into the Imperial territory, and probably it only served to guard the main body from the attacks of hostile tribes in the steppe
