Had Russia avoided the Bolshevik Revolution in 1917 (such as by having both Lenin and Trotsky be killed in two separate pre-1917 accidents--or perhaps even by the Tsarist secret police) and thus made it out of World War I in one piece, what would race relations be like in Russia over the next century (1917-2017)?
For instance, are ethnic minority (Ukrainian, Caucasian, Central Asian, et cetera) parties going to closely cooperate with each other in this TL in order to protect and promote their own interests?
Also, could we see a Russian version of our TL's African-American Great Migration in this TL (specifically with huge numbers of Caucasians, Central Asians, and other ethnic groups moving to the Russian heartland)? :

In addition, are certain ethnic groups in Russia--Caucasians, Central Asians, et cetera--going to demand things such as affirmative action (in order to compensate them for previous Russian Imperialist rule) in this TL?
Finally, how much ethnic intermarriage are we going to see in Russia in this TL? Would the greater freedom of movement (as in, no propiska system) have resulted in greater inter-ethnic contacts and interactions and thus in more intermarriage in Russia in this TL?
Any thoughts on all of this?
