In historiography, the term historical revisionism identifies the re-interpretation of the historical record. It usually means challenging the orthodox views held by professional scholars about a historical event, or introducing new evidence, or of restating the motivations and decisions of the participant people. The revision of the historical record reflects the new discoveries of fact, evidence, and interpretation, which produce a revised history. In dramatic cases, revisionism involves a reversal of older moral judgments about heroes and villains.
At a basic level, historical revisionism is a common and not especially controversial process of developing and refining the writing of history. Much more controversial is the reversal of moral findings, which the heroes, good guys, or positive forces are depicted as villains, bad guys, or negative forces. This revisionism is quickly challenged by the supporters of the old view, often in heated terms. It becomes historical negationism, a form of historical revisionism that presents a re-interpretation of the moral meaning of the historical record. The term “revisionism” is used pejoratively by people who charge that revisionists are distorting the true historical record.
Now, adding my findings. I find that revisionists often rewrite things to suit a modern day mind frame or a certain group of people or input their personal opinion in how they wish things to go. Totally eliminating the ethnic of that day and time. May they be good, bad or downright evil. Which in many cases they are. It’s there. You can’t change the past.
Changing things to suit your view that’s not history. That’s fictional writing. History is the recording of actual events as they actually occurred to the best of your ability not how you ‘feel’ the event should have gone. Again, that’s not history. That’s philosophy. Historians are indifferent to the stories they records.
A real historian deal with facts not their own opinion or emotions. However the subject lived their life that’s exactly how a true historian records it.
