The names of Oleg’s ambassadors who negotiated this treaty of peace, show that all of them were Northmen. From this we may conclude that the government of the country was as yet wholly in the hands of the conquerors. THE REIGN OF IGOR Igor, the son of Rurik, who was married to a Scandinavian princess named Olga (Helga), was nearly forty years of age when he succeeded Oleg in 913. He ascended the throne under trying circumstance, for the death of the victor revived the courage of the vanquished and the Drevlians raised the standard of revolt against Kiev; but Igor soon quelled them, and punished them by augmenting their tribute. The Uglitches, who dwelt on the southern side of the Dnieper, contended longer for their liberty against the voyevod Sveneld, whom Igor had despatched against them. One of their principal towns held out a siege of three years. At last they too were subdued and made tributary. Meanwhile new enemies, formidable from their numbers and their thirst for pillage, showed themselves on the frontiers of Russia: these were the Petchenegs, famous in the Russian, Byzantine, and Hungarian annals, from the tenth to the twelfth century. They were a nomad people, of the Turcoman stock, whose only wealth consisted in their lances, bows and arrows, their flocks and herds, and their swift horses, which they managed with astonishing address. The only objects of their desires were fat pastures for their cattle, and rich neighbours to plunder. Having come from the east they established themselves along the northern shores of the Black Sea. Thenceforth occupying the ground between the Greek and the Russian empires, subsidised by the one for its defence, and courted by the other from commercial motives--for the cataracts of the Dnieper and the mouths of the Danube were in the hands of those marauders--the Petchenegs were enabled for more than two hundred years to indulge their ruling propensity at the expense of their neighbours. Having concluded a treaty with Igor, they remained for five years without molesting Russia; at least Nestor does not speak of any war with them until 920, nor had tradition afforded him any clue to the result of that campaign.
