Well, what I truly need is a hypothetical question that I could find several answers to. I shall go for one and dispute others, maybe, or simply compare things. Tolerance could actually not be defined as a term from the beginning, but throughout the paper. Perhaps I need some evidence that they were, in fact, tolerant towards some people when they needed them.
I was thinking a bit more - I need quite a "small" topic for 3000 words, see - perhaps I may compare Roman Citizenship laws and how they attempted to romanise peoples for their own benefit and compare that to the techniques used in other Empires (e.g. Persian, Mughal, Dutch). They did, effectively, try to do the same thing and strengthen their Empires by attracting talent from other places, cultures, ethnical groups and absorbing it. That is how their armies (pardon the Dutch) became so large, after all. If you try to only use blonde blue-eyed purebloods in your army, you can only have so many.
The only problem is that I cannot seem to be able to pin point any particular little thing from this that I could make the subject of my paper and hypothesis. The topic just seems too grand for 3000 words, non?
I like your ideas, however, and do agree that Romans were far from the Human Rights kind of tolerant! They did however, "welcome" various peoples to live "under one roof" with the actual Romans. That is some tolerance.
Thank you!
