3000+ years of Indian history is too lengthy to accomodate world history to a satisfactory level. Of a 400-page history text-book, perhaps about 20 would have been devoted to 20th Century world history(compared to the unending volumes regarding Indian independence and the politics of the time). And since the bulk of it comes towards the end, most students tend to skip it, so as to rely on the bulk of the rest to score in exams. The availability of question choices in the final examinations also encourage this.
- Most people on Earth have a history that goes back thousands of years.
Countries like Denmark, Norway and Sweden are much older nations than, for instance, India and our civilizations are also thousands of years old (although the Vikings didn’t develop a literature of their own until the era called THE ‘Viking age’, roughly 750-1000 AD), but how could this allow us to forget about neither Nazism or Pol Pot.
According to the logic of your post, it’s okay if people in Greece, Italy and India forget about Stalin and Hitler while Americans, on the other hand, ought to become experts in this field.
