Etymology

The name Russia is derived (1)……….. However, this proper name became more prominent in the later history, and the country typically was called by its inhabitants "Русская Земля" (russkaya zemlya) which could be translated as "Russian Land" or "Land of Rus'". In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus' by modern historiography. The name Rus itself comes from Rus people, a group of Varangians (possibly Swedish Vikings) who founded the state of Rus (Русь).

An old Latin version of the name Rus' was Ruthenia, mostly applied to the western and southern regions of Rus' that were adjacent to Catholic Europe. The current name of the country, Россия (Rossiya), comes from the Greek version of Rus', nowadays spelled Ρωσία instead of Ρωσσία, which was the denomination of Kievan Rus in the Byzantine Empire.
