Olga's origins are not certain. Although she may have come from Pskov, according to the Russian Primary Chronicles, she came from Vyshgorod. She was probably of Varangian heritage. She is believed to have been born about 890. About 903 she married Prince Igor I, who was the son of the founder of Russia, Rurik. Prince Igor succeeded his father Oleg as the ruler of Kiev and its territories, which now constitute parts of a number of present day nations: Russia, Ukraine, Belarus, and Poland.
