Hello there! So you may have already handed this essay in but I’ll reply anyway - though I don’t know exactly too much on this specific topic yet.
So I’ve only just finished how Stalin became dictator in class but I recommend that for your question you take a look into how Stalin was able to transform the Soviet Union from a peasant society into both an industrial and military superpower - though he did do quite a lot of terrible things, he was successful in transforming Russia.
Hope this helps!
