>In Vietnam, we are often taught that, "Russia" means "Eastern Rus", so it is absurd to use "Russia" in the context of the 12th century.
Well, "Russia" has meant different things at different times and places. So whether it is absurd or not depends on which meaning you're using...
Until WW1, and often even after, the discourse in Russian and English imperial capitals and academic centres was that "Russians" are what are called "Eastern Slavs" today, and could further be split into "Great Russians" (Velikorossy), who mainly live in what's now known as Russia, "Little Russians" (Malorossy) who mainly live in what's now known as Ukraine, and "White Russians" (Belorossy) who mainly live in what's now known as Belarus (the country that has kept its name the closest). Kind of like Americans being separated into Yankees, Dixielanders, Appalachians, etc, but with a longer history and more language/dialect divergence.
As a result of WW1, due to both external (Germans conquering and ruling much of the Western Russian Empire for some years) and internal (communists coming to power) forces, the names shifted. But not everybody used the changed terms or was even aware of what this shift of terminology meant or why it was done.
I'm not quite sure, but I have this impression that in the medieval era, and also in the Imperial era until WW1, if you'd asked most people in any of those three regions what they were, they would have said "I'm Russian", and if you asked them to specify further, they would have said "I'm Great Russian" or "I'm Little Russian" or "I'm White Russian". After WW1, the "Great Russians" kept answering "I'm Russian" but the others were encouraged to not answer that way any more, and their native language/dialect variations were heavily promoted by the state (for various reasons, such as wanting the Soviet state to be more multicultural).
Perhaps if the capital of the East Slavs had stayed in Kiev/Kyiv, the locals would have gained more territory than they ended up having and been proudly calling THEMSELVES the "Great Russians" and eventually simply "Russians", while the people living in Moscow might've been encouraged to call themselves Novgorodians or Pomorians or something, and speaking Novgorodian or Pomorian which honest-to-goodness has nothing to do with "Russian", and is a member of the civilized Scandinavian family of nations... ;)
So eventually, you got the current situation where "Russian" usually means what "Great Russian" used to mean (in English it can also just mean "citizen of Russia", while in Russian that's two different words), and "East Slav" means what "Russian" used to mean.
But the famous 19th century writers are still widely read, so the old meanings are not forgotten either! It causes a lot of misunderstandings, since two people can use the same words and mean very different things by them. If you want to increase the risk of eventual conflict between people, that's a pretty good way to do it...
