The Unwritten History in our Textbooks

In his book “The Dacians”, Hadrian Daicoviciu showed that “only a few pages have been preserved of the great book of this people’s ancient history; dozens of pages, undoubtedly among the most interesting, were lost forever and many, perhaps even more interesting, were never written by ancient authors”. There is a text that keeps coming to my mind very often, especially lately, because I have noticed that there is a tendency to remove or skip several pages of our history. The mission of a historian is to try to find out the historical truth with as many pages as possible. We should not overlook, we should not mitigate anything from our past. The lost or unwritten pages of history hinder this mission, it is true, but what should we do about the pages that were written and, deliberately, are not included in the history books?
