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.
