It was at the end of the tenth century – tradition says 988 – that Russia (or, at any rate, its people, the Rus) became Christian, under Prince Vladimir the Great (c.956–1015), monarch of Kiev and Novgorod, who secured unchallenged rule over his dominions in 980.
Absolutely lame historical claim; its ruth, not rus; its Kyiv not Kiev; In 10th century there was no Russia or russian territories, author is biased.
