Sorry, but no politics.

Just because it involves politics does not make it against the rules in this sense. This is straight, hopefully unbiased history we're attempting to deal with. It would certainly be more political if I simply said," I approve of Marxist-Lenninist Socialism, so capitalism can svck it." However, I am not. It is a discourse on the past which happens to involve a political system. We're not saying whether we agree with it or not.
These are pretty huge topics, maybe if you narrowed down some of your questions somebody might be able to help you out. Like when you mention NEP, maybe you could ask how effective it was, whether it was a breach of ideology (not sure if allowed by forum rules though), or you could ask what the New Economic Policy was if you aren't entirely sure about that.
Yeah, I apologize for that. I tend to go broad when I study so I can consider all the important points. Once I have a hold on things, I usually narrow my focus.
We'll go with your NEP question. Why did it come about? What did it entail? How did it effect the Russian population? Was there dissent within the Bolshevik party or unanimous support? What were the negative aspects of NEP? Was it effective?
I see some moderators are peering over this topic now. In the hopes that it stays historical and not political, I'll post...
One of the more interesting aspects in the start of the Soviet Union is the conflict between Stalin and Trotsky. Both had different views. And it's the way Stalin "won" is study worthy, I think.
Have you read the book "Animal Farm"?
No, I have not read Animal Farm, but I am aware that it is a sort of allegory by Orwell. Stalin's rise in power is interesting, I agree, especially considering how he often flip-flopped on certain policies.
Problem is, even the questions you have asked cannot really be discussed without bringing politics in. And the Soviet era is still fresh enough in enough minds that talking about that piece of 'history' can stir up all sorts of stuff.
I think about the most recent you can reliably go around here is the 1800s

. But sometimes the mods go easy and give things some slack + extra attention so you may get lucky

While I agree that certain subjects may demand careful consideration because of how fresh they may be in human history, I have to say that the early Soviet period is probably okay to touch on.
