Historical revisionism affects national identity by reinterpreting past events to align with contemporary values or narratives. This process can shape collective memory, influencing how citizens perceive their history and, consequently, their identity. For example, revisionist narratives may emphasize certain aspects of a nation's past that highlight heroism or victimhood while downplaying less favorable events. This selective retelling can foster national pride or guilt, impacting social cohesion and political engagement. Ultimately, historical revisionism plays a significant role in defining a society's self-perception and informs current political debates regarding identity, values, and policy-making.
