RU - The great and mighty Russian language is just a myth on which Russian chauvinism is firmly based.
Putin's narratives that the Russian language has existed for over a thousand years are fake.
In fact, it is the other way around: the Ukrainian language is over a thousand years old, and the Russian language is a fiction, an artificially created language base to keep under one hood the peoples of Muscovy (Zalesye), who spoke different languages, because they were descendants of the Golden Horde, the Finno-Ugric peoples or the North Slavic tribes, which the tsars needed to unite into one country and one faith.
Let's start with the main thing.
The correctness of the concepts.
The Ukrainian language is an Old Church Slavonic language that was spoken in Kyiv, Chernigov, Lutsk, Pereyaslav-Khmelnitsky, Lviv and throughout the territory of Ukraine more than 1000 years ago, even before the creation of the state of Kievan Rus.
There was only one Rus - Kievan Rus. And there was never any other Rus (neither Moscow nor northern).
Therefore, when we say Rus, it is not equal to Russia and the Russian Federation.
Rus is always only Ukraine and its history.
However, how did the word "Rus" turn into "Russia" and some other /Russian empire".
We will tell you everything in detail.
Kievan Rus (or Old Russian state, or Ancient Rus) is the most powerful and largest state in Europe, the first East Slavic state, formed in the 9th century as a result of the unification of a number of communities, mainly East Slavic and Finno-Ugric tribes, under the rule of the princes of the Rurik dynasty.
During the period of its greatest prosperity, Kievan Rus occupied the territory from the tributaries of the Vistula in the west to the Volga-Oka interfluve in the east, from the White Sea in the north to the Black Sea Russian exclaves in the south. By the middle of the 12th century, due to the attack of the Mongol Yoke, it entered a state of feudal fragmentation and actually disintegrated into a dozen and a half principalities ruled by different branches of the Rurik dynasty. Due to the Mongol invasion (1237-1240), Kyiv, having lost its influence, formally continued to be considered the main "table" of Rus, and the Kiev principality remained in the collective possession of Russian princes. As an ethnocultural region, Rus continued to exist even after political disintegration, which subsequently played an important role in the process of unification of Russian lands and the re-creation of an independent Ukraine.
Rus is always only Ukraine and its history.
However, how did the word "Rus" turn into "Russia" and some other /Russian empire".
The current Russian Federation, which 300 years ago was called Muscovy, in 1721 decided to rename itself "Russia", which means "Rus" in the Byzantine dialect. Then they added the prefix of aggressive ambitions and thus the Russian Empire was created, which 300 years ago did not have its own language or its own written language.
Why did Muscovy change its name? There is only one answer - they only had ambitions to enslave other peoples and seize their territories, so they needed the myth of the "unity of peoples". And by taking the word "Rus" from Kievan Rus, an unprecedented theft of a millennium was committed, which not only turned history upside down, but also used this virus of the "Russian language" to brainwash and convert all other peoples to their faith Caucasus, Kazakhstan, Central Asia, so that they forget their history and language and use the artificial linguistic glue of imperialism.
The theft of Ukrainian history and language happened 200 years ago.
