As per our rules

Our users aren't here to do your homework for you, but they might be willing to help. Remember: AskHistorians helps those who help themselves. Don't just give us your essay/assignment topic and ask us for ideas. Do some research of your own, then come to us with questions about what you've learned. This is explained further in this [META] thread.

Have a look at what sources you have, or do a Jstor search by keywords for articles relating to the theme, then look at the sources (primary and secondary) those authors use to build a shortlist of books and articles to read (ie. your preliminary bibliography). Read those sources and the repeat the process. You sound like you've put little or no thought beyond a general theme yet, this process is one should do to begin your research, well before you start writing, to identify your line of investigation.
