I have to do a history project on a topic in world history since 1500 CE. The requirments are that the topic must be debatable, with evidence to back up the claims, and not from American History. I would love to do my project on some area of Japenese history particularly the Warring States period if possible, but I don't know enough about Japan's history to know if I should look elsewhere for my topic. Any suggestions would be welcome.
