Общее средневековое происхождение России и Украины

The Primary Chronicle (Old East Slavic: Повѣсть времѧньныхъ лѣтъ, romanized: Pověstĭ vremęnĭnyxŭ lětŭ, lit. 'Tale of Bygone Years'),[a][2] shortened from the Russian Primary Chronicle,[b] is a chronicle of Kievan Rus' from about 850 to 1110.[4] It was compiled in Kiev in the 1110s.[5] Medieval tradition attributed the work to the monk Nestor the Chronicler (hence Nestor's Chronicle), but modern scholars consider it an anonymous compilation edited by several authors, including Hegumen Sylvester of Kiev in 1116
