Hello! I noticed there were no comments on this and although I can't offer as in depth an answer as I'd like I can definitely offer something.

History did change after the Bolshevik revolution - a lot!

In general the history of Russia was reintepreted through the Marxist dialectical theory of History. I'm simplifying a bit here but what Marx generally argued is that the locomotives of history is driven by economic factors and material conditions that would change the relationships between the rulers and ruled (bourgeoise and proletariat).

In response to this the Bolshevik interpretation of history changed. Different events were seen as 'heroic' and 'great' no longer were the wicked Tsars venerated but instead they were criticised. Popular movements against the Tsar like the Decembrist movement or the Pugachev revolt were celebrated (this could do with verifying however I don't have sources at hand).

However this changes during the Great Patriotic War. Under Stalin popular Russian figures like Alexander Nevsky, Ivan Grozyni (the Terrible) and Peter the Great were likened to Stalin. They were held up as proud Russian heroes who had conquered Russia's enemies before like Stalin would with the Germans.

As you can see the narrative of Soviet history shifts from being about the proletariat's struggles with the rulers to the rulers being presented as protectors of the people. This narrative was only really maintained during the war and once the Soviet Union had defeated the Nazi's I imagine the study of history once more returned to this idealised vision of the proletariat in Russia's past.

This is all I can really offer on the question - apologies for vagueness.
