Vladimir I Sviatoslavich or Volodymyr I Sviatoslavych, given the epithet "the Great", was Prince of Novgorod from 970 and Grand Prince of Kiev from 978 until his death in 1015. The Eastern Orthodox Church canonised him as Saint Vladimir.

Old East Slavic was a language used by the East Slavs from the 7th or 8th century to the 13th or 14th century, until it diverged into the Russian and Ruthenian languages. Ruthenian eventually evolved into the Belarusian, Rusyn, and Ukrainian languages.
