Answer:
It entirely depends, but I have a few ideas.
Step-by-step explanation:
If you're doing world history, try researching Vlad the Impaler. He was pretty much real-life Dracula, and the way he was overthrown was pretty interesting. If you're doing U.S. History, try researching prohibition. It created entire sports! If you're doing history for any other country, just tell me, and I'll come up with something!
