Smolensk, Lubetch and Kief were captured, and Askold and Dir put to death. Between the years 879-912, Oleg organized the Russian empire. For the sake of commerce, he tried to preserve peace with the Greeks, but when difficulties arose he called in new armies from Sweden and great expeditions started against Byzantium. But these Variagi were an unruly element, and, in order to satisfy their desire for war and booty, the Russian rulers always let a plundering expedition to the Caspian Sea follow every unsuccessful attack upon Byzantium; also when war with the Greeks was avoided through decrees of peace, expeditions to the Caspian Sea took place. These expeditions against the Arabs, who inhabited the coasts of the Caspian Sea, were neither in any marked degree successful. Masudi is the first author among the Arabs who mentions the expeditions of the Swedes. They came down the river Volga in their ships. The Arabs describe the “Rûs” as blond and “tall as palm-trees.” The burial of a Rûs is described by Ibn Fosslan, who visited Bulgaria in 921. “The hero was burned in a ship with weapons, horses, dogs and a woman.” In 965, the Israelite, Ibrahim Ibn Jakub, made a journey to Germany. He tells that the Arabs in his day with Rûs (Russians) meant partly the Swedes of Sweden, “who often came in ships from the West to plunder,” partly the Swedes settled in Russia, “who speak the language of the Slavs, on account of admixture with them.” It was the destiny of the Swedes in Russia to exchange their language for that of the Slavs and finally to absorb Slav customs. Such might not have been the case if they had been greater in numbers, or if their coming had been deferred to a later, Christian period, when to a strong form of government would have been added a strong Church organization. Yet their influence was greater than that of the Vikings in any other country, for the Russian empire was entirely a Northern creation. To follow further the Rurik dynasty would lead us away from Swedish into Russian history. But let us mention that Oleg was succeeded by Rurik’s son Igor, who also was a great war-lord, and undertook the third expedition of Russians and Variagi against Byzantium. His widow was the celebrated Olga, who was converted to Christianity and afterward canonized. She reigned during the minority of her son Sviatoslaf, whose conversion she was never able to effect. Sviatoslaf’s son and grandson, Saint Vladimir and Jaroslaf the Great, were the Clovis and the Charlemagne of Russia.
