There is an ongoing controversy in Pakistan South Asia 's pre-Islamic history. The pre-Islamic history of South Asia deals with Hinduism, Buddhism and the many empires including Mauryan Empire of Chandra Gupta Maurya.
The present History texts in Pakistan talks about the Indus civilization and skips Hinduism, birth and spread of Buddhism and the rule of Hindu kings in the region that forms present day Pakistan.
Mir Shakil-ur-Rahman writes in an editorial in The News
After all, these civilizations are very much a part of our history, whether the MMA likes it or not. It is not Hindu history, as the MMA would have it, but Pakistani, and, in fact, world history. If Hinduism and Buddhism, or, for that matter, any other culture or religion, are a part of this history, then they, too, must be covered.
History is always written by the victor. Today, the ruling class around the world distorts history for their needs. We had numerous such controversies in India
Ancient seers of Hinduism rarely bothered about history because history, mostly, inflates egos and acts as catalyst for violence.
