Historical narratives shape national identity by influencing collective memory and how communities perceive themselves in relation to others. These narratives often emphasize certain events and figures while marginalizing others, constructing a cohesive identity that can foster unity or division. Historical reinterpretations can impact patriotism and social cohesion, influencing how citizens understand their country's values and mission. Additionally, the narratives adopted by governments can legitimize current policies and actions, reinforcing a sense of entitlement or responsibility in the global arena.
