And before the Revolution, Tsarist regime did even more horrowing things to its people. Sadly Russia never had a ruling entity that was good. Well there was hope in the 80's with Gorbachev and Krushev with his Thaw period, but these were short lived and the system went back to its stable state of terrorizing its citizens.
You sound nonsensical. Russian government did enslave russian population?? Just remember that "coincidentally" the whole Romanov (that's a stage name) family are germans. And official history is even more coincidentally was (over)written by germans.
Thing to remember is the Russian Revolution of 1905 changed the structure of the Russian government to a constitutional Monarchy. That's what the communists overthrew and replaced with something far worse.
