But the Holocaust went further. It's believed that over 10 million civilians were killed during the Holocaust. Over three million prisoners of war were killed. And other people, including several hundred thousand Romani often referred to as gypsies, several hundred thousand people with disabilities, many thousands of homosexuals were all put to death during the Holocaust. Now we've covered a lot of world history, and a lot of it, unfortunately, has a lot of death, a lot of destruction, and sometimes targeting people for their ethnicity. But never in world history have we seen something at this scale. And because it seemed to be a relatively new concept, a term was coined, genocide.
