Yes... the Interbellum period is really interesting.I find the time between World War I and World War II to be rather interesting, mostly seeing the rise of Hitler.
And while it's not exactly a period of History, I do have a rather morbid fascination of the Modern History of Human Experimentation. It really is a downer when you read the soulless atrocities that people did just to torture people and experiment with drugs (here's looking at you MK Ultra).
