One particular historical event can be used as an example here.

Go out and buy a general UK history book today. Look at the chapter on Richard III. It will probably tell you that he was an evil, deformed tyrant who killed his brother and his nephews, poisoned his wife in order to marry his neice, in order to become King of England.

All complete bollocks.

There was a retraction published after the death of Elizabeth I (the last Tudor monarch), all the evidence points towards Henry Tudor being the bad guy, something that historians choose to ignore.

All history is bunk.
