Again, not going to belabor this...people conquered by others...populating new lands with new people and calling it "historical" presence...well, sure Nazis had a "historical" presence in Russia in WWII, too bad they didn't leave squatters to lock-in that "historical" presence, eh?
I find it incredulous when people find it difficult to understand when conquered people bristle at being dominated in the slightest by the same people...
I guess the lesson is obvious...genocide, if no one is left to bitch about it there isn't a problem, eh?
Who was conquered, say in the Donbass? What group was conquered, when, and by what group?It helps to provide dates as you did above. Germans invaded Russia the last time in WWII. I think that Russia (Peter the Great?) imported lots of German farmers to maybe Volgograd to teach Russians better farming techniques. They had limited self government and spoke German. They got kicked out after some war with Germany.
It helps to know some history. When did the ethnic Russians some to the area of Kharkhov and Crimea? What group was there before? How about Tatars? Hungarians? When did the ethnic Ukrainians come to the area of Kiev? How about the Poles and Ukrainians to Lvov? Maybe Lvov had Polish landlords and Ukrainian serfs. The answer may be that those groups were there for a long time, hundreds of years, and govts drew map lines around them. It did not much matter which part of the Russian empire you were from even after Lenin drew lines to create Ukraine SSR. . Trouble comes when some group decides the whole place belongs to them often because of some mythology.
In Balkan Ghosts, Kaplan said that for every hectare in the Balkans there are 3 or 4 groups who once ruled there and some think they should again.
People with no knowledge of history think there was a country called Ukraine where people spoke Ukrainian and the place was invaded by Russians. That is very ignorant and very wrong. Lenin drew lines on a map and named the SSR Ukraine as Ukraine means border or borderland as it was the border land of the Russian empire. Some maps labelled the border region Ukraine. Ukr NAZI infused militants drank the NAZI cool aid and decided that since the SSR, then country, was named Ukraine that only Ukrainians belonged there. I heard different statistics but one was that 37% of people in Ukraine IDed as Russian before the coup. I recall another was only 20%. Donbass was mostly Russian with some ukr migrating in for industrial jobs.
I do not know who was in Kharkov before ethnic Russians came or near Kiev when Ukrainians came etc. Preindustrial societies often do not support high population densities. So maybe not many people. I do not think that eastern Ukraine was filled with ethnic Ukrainians. It does not help that such people had no standardized language and were mostly illiterate, save some priests. Russians have been in Sevastopol with the Russian black sea fleet since before the US was a country. Maybe they kicked Turks out. Stalin deported some Tatars from Crimea and imported some more Russians and some Ukrainians.
I heard a woman talk in Chicago on youtube. She was born in the Ukraine SSR then grew up after the USSR fell. I do not know the exact years. She said they used the same science and math books every year but the history books were re-written every year and replaced.
I hear the words that come out of the mouths of various groups on social media, especially videos. The Russians call the Ukr brother Slavs and think they went crazy. The Ukr militants think they are almost a different race and are not afraid to say so. They say they want to drive the subhuman Russians (civilians) out of Donbass. I think many raise their kids from birth to hate Russians and have for a long time. I learned that people were hung from trees in Lvov 1915-18 for speaking Russian. I heard someone say they went to a Russian city maybe Moscow and everyone in the room had at least one Ukr grandparent. That NAZI cool aid and racial mythology is bad for everyone.
