Historical revisionism

In historiography, historical revisionism is the reinterpretation of a historical account. It involves challenging the orthodox scholarly views or narratives regarding a historical event, timespan, or phenomenon by introducing contrary evidence or reinterpreting the motivations of the people involved. Revision of the historical record can reflect new discoveries of fact, evidence, and interpretation as they come to light. The process of historical revision is a common, necessary, and usually uncontroversial process which develops and refines the historical record to make it more complete and accurate.
