The drujina and warriors did not take kindly to Christianity. They, as well as the peasants, preferred to worship Perun and Voloss. The same thing happened elsewhere. Christianity made the greatest progress (p. 037) in cities, whereas the dwellers on the "heath" remained "heathen." "When one of the warriors of the prince wished to become a convert," says Nestor, "he was not prevented; they simply laughed at him." When Olga returned from Constantinople, she was anxious that her son, who was of age and had succeeded to his father, should follow her example. Sviatoslaf refused; "my men will laugh at me," was his usual answer. Nestor mentions that he sometimes lost his temper. Christianity did not make much progress during his reign.
He was a warrior, like his Norse ancestors. In the brief time of eight years, 964-972, he found time to wage two wars. The first was with the Khazar empire on the Don. Sviatoslaf captured its capital, the White City, and received tribute from two tribes of the Caucasus. The second war did not turn out so well.
From Nestor's account and that of Leo the Deacon, it appears that the Byzantine emperor, wishing to make use of Sviatoslaf, decided to find out what sort of man he was. He therefore sent him presents of gold and fine clothes, but the grandson of Rurik would scarcely look at them and told his warriors to take them away. When the emperor heard this, he sent him a fine sword and other weapons; these were accepted with every token of satisfaction by Sviatoslaf. When the emperor was informed of the result, he exclaimed: "This must be a fierce man, because he despises wealth and accepts a sword as tribute."
This did not prevent the emperor, who had a private quarrel with Peter, Czar of Bulgaria, from urging Sviatoslaf to make war upon (p. 038) his enemy. The Russian gave a hearty consent, and in a very short time he captured several fortresses and Peréiaslaf, the capital, fell into his hands. He determined to transfer his capital there, and when he returned to Kief, he told his mother of the city on the Danube. "The place," he said, "is the central point of my territory, and abounds in wealth. Precious goods, gold, wine, and all kinds of fruit, come from Greece. Silver and horses are brought from the country of the Czechs and Hungarians, and the Russians bring money, furs, wax, and slaves."
