Hi all,

I'm doing a research paper for my English class, and I'm doing my paper on the dangers of revision regarding unpleasant historical events, like genocide. My professor told me to focus on three genocides/mass killings that receive significant revision and denial, be it from governments or political/social groups.

I have chosen the Holocaust and the Armenian genocide as two of them, focusing on neo-Nazis anti-semites and the Turkish government respectively, but I can't really seem to find a third event. I thought of doing WW2 Japanese war crimes, but after doing some research, the events don't really seem to be denied, ignored or contested in any significant amount today. The theme of my paper is that denial and much of historical revision of genocide-like events is just a continuation of the genocide, and I just can't seem to find a third event to utilize.

So my question -- outside of the Holocaust and Armenian genocide -- what are historical events involving mass killings that are denied/contested of validity for me to research?

Any help is appreciated. I'm really stuck.
