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.
