Institutions and political movements are weaponizing historical revision and selective interpretation of the past to consolidate power and reshape national identity. This goes beyond education or cultural preservation to become an active tool for legitimacy, with competing narratives about colonial legacies, founding ideals, and ancestral claims becoming primary battlegrounds for contemporary political control. Nations frame historical grievances as justification for present-day geopolitical moves, and leaders use reinterpreted history to validate exclusionary ideologies.
