Yeah, I think there are a lot of both Roman and Nazi influences in Star Wars.
Roman and mythology in more or less in the greater scope of the galaxy and the golden age of the Republic, and a lot of Nazi influence as far as the Empire and the Emperor are concerned. Palpatine hates all non-humans... the Empire is pretty much 100% human in the military... very Nazi-esque in their disgusting hatred of non-Aryans and those that weren't pure blood German...
It's all very cool, but at the same time pretty disturbing if you really think about it, especially considering how many people are so fascinated with the Empire.
