James Alexander Thom said this quote
“ Most historical accounts were written by fallible scholars, using incomplete or biased resource materials; written through the scholars' own conscious or unconscious predilections; published by textbook or printing companies that have a stake in maintaining a certain set of beliefs; subtly influenced by entities of government and society — national administrations, state education departments, local school boards, etcetera — that also wish to maintain certain sets of beliefs. To be blunt about it, much of the history of many countries and states is based on delusion, propaganda, misinformation, and omission. ”
