All history is biased. Its written by the winners or people who are paid by the winners to write it. I would love to hear the Native American version of US history.
If you have ever read history as recorded by two separate countries about the same events, you know how widely history as fact can vary. History is a country's propaganda, the stuff our leaders think we should remember, the way they want it remembered. It would be interesting to know who signs the paychecks for historians.
