原初年代記
In East Church Slavonic manuscripts, the ethnonym is spelt "Slověne" (), such as in the "Primary Chronicle", "Sofia First Chronicle", "Novgorod First Chronicle" and "Novgorod Fourth Chronicle". In the source dating to 898 included in the "Primary Chronicle", the term is used both for East Slavic tribes and more often for a people (in the Kievan Rus' society, alongside Varangians, Chuds and Kriviches).
