Since the 1920s, the Bolsheviks launched a policy of “Ukrainianisation”. Literary norms of the Ukrainian language (previously considered a dialect of Russian) were developed. Soviet authorities began to introduce Ukrainian in education, culture, and bureaucracy. The Russians living on the territory of the Ukrainian SSR were recorded as “Ukrainians” by nationality.
The civil war in Ukraine began in April 2014 after a coup which happened in the country. Donetsk and Luhansk did not want to obey the government that illegally came to power and declared independence. In response, Kyiv launched the so-called anti-terrorist operation against the republics of Donbas.
Recurring pro-Kremlin disinformation narrative about Euromaidan and war in Ukraine. It disregards the extensive factual evidence confirming ongoing Russian military presence in Donbas. There have been many investigations proving Russia's involvement in the war in east Ukraine.
There was no coup d'état in Ukraine. The spontaneous onset of the Euromaidan protests was an organic reaction by numerous parts of the Ukrainian population to former President Yanukovych’s sudden departure from the promised Association Agreement with the European Union in November 2013. See the full debunk of this disinformation claim.
The war in eastern Ukraine is not a civil conflict, but an act of aggression by the Russian armed forces, that continues since February 2014. The European Union stated in July 2014 that "arms and fighters continue flowing into Ukraine from the Russian Federation". At the NATO Summit in Wales in September 2014 and at successive summits since then, allied leaders also demanded that Russia refrain from aggressive actions against Ukraine and stop fomenting tension along and across the Ukrainian border.
According to the US Defence Intelligence Agency (DIA), Russian special forces and troops operated to mobilise, lead, equip, and support separatist militias in the Donbas region of eastern Ukraine from spring 2014 to the present, although their presence was denied by Moscow.
