How do lessons in history vary based on where you live?

We were taught that as Australians we'd killed off the Aboriginals, well, most of them. And as decedents of the British Empire, that we'd tried to do the same to every other native people in the world. But we were also taught that the British army sent Australian soldiers to their deaths in WW1 and how that was wrong and blah blah blah blah. But WW1 was everybody's fault. Oh but we were the heroes of WW2 along with the Americans and British. But generally we were told by our teachers that we had treated a lot of people badly, and that those native people were living in peaceful, wonderful savage but noble existence before we turned up. Which isn't true, humans are humans and sooner or later one group of humans will bump into another group of humans and they will do the wrong thing. The Aboriginals of Australia were kicking the shit out of each other, just as our ancestors had been, long before we showed up, we were just better at it and there were more of us.

In Canada, at least when I was in school, we don't get taught about how the cultural genocide committed against the indigenous peoples, and our own part in slavery. People are still very racist against indigenous people here.

history books are written in a way to be at least plausible to most of the audience. the only reason anyone is forcefully told to learn the history of something is because they want you to view things from their perspective.

many times in history people in power went around burning all the books so they could start over for the next generation
