Why do historians hide the cities of Tartary and the pyramids in Siberia?

The idea that historians are hiding the existence of cities in Tartary or pyramids in Siberia is part of a series of conspiracy theories and fringe theories that lack credible evidence. These theories often arise from misunderstandings of history, archaeology, and the nature of historical research. Tartary, a term used in historical maps and texts, referred to a vast region in Asia, primarily inhabited by various nomadic peoples. While it is true that this area has a rich history, the notion that there are hidden cities or advanced civilizations in Tartary is not supported by mainstream historical or archaeological scholarship. Similarly, claims about pyramids in Siberia often stem from misinterpretations of natural formations or other structures that are mistaken for pyramids. Mainstream archaeology has not found evidence of ancient pyramids in Siberia akin to those in Egypt or Central America. Historians and archaeologists work based on evidence, peer-reviewed research, and methodologies that are open to scrutiny. If credible evidence for such cities or structures were to emerge, it would be subject to rigorous examination and would likely receive attention in scholarly work. Claims of suppression or concealment typically lack a basis in factual accuracy and often reflect a misunderstanding of how historical research operates.
