Early Russian History

Eastern Slavs
Many ethnically diverse peoples migrated onto the East European Plain, but the East Slavs remained and gradually became dominant. Kievan Rus', the first East Slavic state, emerged in the ninth century A.D. and developed a complex and frequently unstable political system that flourished until the thirteenth century, when it declined abruptly. Among the lasting achievements of Kievan Rus' are the introduction of a Slavic variant of the Eastern Orthodox religion and a synthesis of Byzantine and Slavic cultures. The disintegration of Kievan Rus' played a crucial role in the evolution of the East Slavs into the Russian, Ukrainian, and Belorussian peoples.

The Inhabitants of the East European Plain
  Long before the organization of Kievan Rus', Iranian and other peoples lived in the area of present-day Ukraine. The best known of those groups was the nomadic Scythians, who occupied the region from about 600 B.C. to 200 B.C. and whose skill in warfare and horsemanship is legendary. Between A.D. 100 and A.D. 900, Goths and nomadic Huns, Avars, and Magyars passed through the region in their migrations. Although some of them subjugated the Slavs in the region, those tribes left little of lasting importance. More significant in this period was the expansion of the Slavs, who were agriculturists and beekeepers as well as hunters, fishers, herders, and trappers. By A.D. 600, the Slavs were the dominant ethnic group on the East European Plain.

By the ninth century, Scandinavian warriors and merchants, called Varangians, had penetrated the East Slavic regions. According to the Primary Chronicle , the earliest chronicle of Kievan Rus', a Varangian named Rurik first established himself in Novgorod, just south of modern-day St. Petersburg, in about 860 before moving south and extending his authority to Kiev. The chronicle cites Rurik as the progenitor of a dynasty that ruled in Eastern Europe until 1598. Another Varangian, Oleg, moved south from Novgorod to expel the Khazars from Kiev and founded Kievan Rus' about A.D. 880. During the next thirty-five years, Oleg subdued the various East Slavic tribes. In A.D. 907, he led a campaign against Constantinople, and in 911 he signed a commercial treaty with the Byzantine Empire as an equal partner. The new Kievan state prospered because it controlled the trade route from the Baltic Sea to the Black Sea and because it had an abundant supply of furs, wax, honey, and slaves for export. Historians have debated the role of the Varangians in the establishment of Kievan Rus'. Most Russian historians--especially in the Soviet era--have stressed the Slavic influence in the development of the state. Although Slavic tribes had formed their own regional jurisdictions by 860, the Varangians accelerated the crystallization of Kievan Rus'.
