[quote=gcold]Since the USSR only existed after 1922, your history should be focused on the period between 1922-1953, though it wouldn't hurt to go into a bit of Russian history before that.Analysis is like a brief prediction of your nation's future directions, take a look at UK and PRC's profile, something like their analyses would be good.

I'd say the stuff leading up to 1917 and onwards is pretty relevant because of the revolution. I'll just use my own judgement on this since Soviet history is one of my strong points.
