No, it isn't. The historical region is called Rus. Not the same thing.

It is, though. In other languages the etymology is even clearer. In German the place is called Russland for instance.

No, it isn't. Ruthenians, Belarusians, Ukrainians, and Russians are all descendants of the Rus. Belarus does not mean "White Russia", it means "White Rus."

> Originally, the name Rus' (Cyrillic: Русь) referred to the people,[1] regions, and medieval states (9th to 12th centuries) of the Kievan Rus'. In Western culture, it was better known as Ruthenia from the 11th century onwards,[2] Its territories are today distributed among Belarus, Northern Ukraine, Eastern Poland, and the European section of Russia. The term Россия (Rossija), comes from the Byzantine Greek designation of the Rus', Ρωσσία Rossía—spelled Ρωσία (Rosía pronounced [roˈsia]) in Modern Greek.

Using exonyms to determine the "real" name of a place is also a very odd choice.

Historical region called Russia (Русся), but suffix -sia (-sia) was dropped in Slavic language, because it means this/there: Russia (Русся) -> Rus` sia (Русь ся), Rus` there.

Russia founded by descendants of Russia town, now called Old Russa (Старая Русса), which left their town due to epidemic of plague of Justinian.

Russia didn't exist until nearly a thousand years after the plague of Justinian. Unless you just mean the plague?

In either case, Rus comes from the Scandinavians, not from the Slavs.
