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 unstabl
e 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 cul
tures. 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 warfar
e 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 importa
nce. 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.
Little is known of the origin of the Slavs. Philologists and archaeologists theorize that the Slavs settled very early in the Carpathian Mountains or in the area of present-day Belarus. By A.D. 600, they had split linguistically into southern, western,
and eastern branches. The East Slavs settled along the Dnepr River in what is now Ukraine; then they spread northward to the northern Volga River valley, east of modern-day Moscow, and westward to the basins of the northern Dnestr and the western Bug riv
ers, in present-day Moldova and southern Ukraine. In the eighth and ninth centuries, many East Slavic tribes paid tribute to the Khazars, a Turkic-speaking people who adopted Judaism about A.D. 740 and lived in the southern Volga and Caucasus regions.
