First, I’d advise against using the term “oriental”. It’s generally considered outdated and a bit offensive.

Second, you are taught more about Western history. Who is the “we” you are referring to? Students in China or Japan are not taught primarily about western history. Students in the west are taught primarily about western history because, well, it’s their history. Don’t get me wrong, it would be useful for everyone to learn a general history of every place, and probably help cross-cultural communication a ton. But there’s limited space in history curriculums, and nationalism is a powerful force. People want to learn about their own history, and therefore countries teach their own history. This is even true in the west - take something like the American Revolution. It’s a big deal in the American curriculum, but a minor footnote in the British curriculum.

Frankly, the framing of your question is incredibly Eurocentric. It assumes as default that everyone using Reddit is a westerner. Also, this really isn’t the sub for a question like this.

Hi there! You’ve asked a question along the lines of ‘why didn’t I learn about X’. We’re happy to let this question stand, but there are a variety of reasons why you may find it hard to get a good answer to this question on /r/AskHistorians.

Firstly, school curricula and how they are taught vary strongly between different countries and even even different states. Additionally, how they are taught is often influenced by teachers having to compromise on how much time they can spend on any given topic. More information on your location and level of education might be helpful to answer this question.

Secondly, we have noticed that these questions are often phrased to be about people's individual experience but what they are really about is why a certain event is more prominent in popular narratives of history than others.

Instead of asking "Why haven't I learned about event ...", consider asking "What importance do scholars assign to event ... in the context of such and such history?" The latter question is often closer to what to what people actually want to know and is more likely to get a good answer from an expert. If you intend to ask the 'What importance do scholars assign to event X' question instead, let us know and we'll remove this question.

Thank you!
