It did. Crushing pre-existing Russian national pride was central to Soviet dogma, they called it "великодержавный шовинизм".

Dogma and reality often differed quite a bit in the Soviet Union; I would say that the evidence is that the USSR did not actually crush pre-existing Russian national pride, although they managed to temporarily transfer the outward expression of that pride into what was, at least superficially, expression of pride in the Soviet State rather than the Russian nation. This still, though -- despite the internationalist orientation of the Leninist ideology -- retained a substantial nationalist tinge, even if oriented around a new and somewhat broader national identity.
