The philosophy of history is an interesting subject. Plainly though one need differentiate actual history from the academic investigation and writing of history books. The history of the world is what it was, historians can only discover it and hopefully accurately reconstruct abstracts of what actually occurred.
If one thinks about it there are particular reasons why the quantitative distribution of history works and projects have developed unevenly regarding modern nations and people that are logical. It would be wrong to assume that publlc education management selections of what to teach in schools equals the quantity or quality of history books actually existing in the world. Consider one obvious fact though that influences what books school administrators encounter; they need choose books written in the language they are teaching students. In the United States the language used is English and thus history books written by English speaking people with their viewpoint have comprised the bulk of selections and instructions to students. That is a western point of view.
One of the most fun points of learning general history is in finding areas to learn about that are completely new. After reading for some time most of the history of world regions becomes exhausted. One must look into more detail to learn new things regardless of it being Asian, African, Latin American, Canadian, Russian or U.S. history etc.
Writing history books also requires a particular environment and standard of living. The Inca 'wrote' or recorded history books in rope knots that no one can translate today. The high humidity of African, South American and other jungles rot paper. Cave paintings remain in some places for tens of thousands of years yet perhaps not graphic novels without language. Prehistory leading to places that could transition to language inscribed on clay tablets i.e. Mesopotamia and ancient Sumer created more channels for recording history than the far north after 25,000 B.C. when humans began to move there in small numbers as the Wisconsin Ice Age slowly ended. The far north environment did not help produce paper making or written languages and historical and social advances that follow as technical knowledge quantity can be kept with increasing range.
Much history publication followed the invention of the printing press in the west. In China there is much historical material available, and of course poetry. There is a good recent series that recounts some of the Fall of Civilizations on Han China including the experience of a poet returning to his hometown that was a burnt down former imperial capital. One could write quite a bit on the philosophy of history, yet I have other interests presently.
