Oka River
The Oka is a river of European Russia, about 1,500 kilometres long, the largest right-bank tributary of the Volga, which it joins at Nizhny Novgorod. Rising south of Oryol, it flows past Kaluga, Serpukhov, Ryazan and Murom. In the Middle Ages its banks were the land of the Vyatichi and of principalities such as Ryazan and Murom, and its middle course long formed Muscovy's southern defensive line against the steppe.
