As once-colonized nations seek to stand on their own, the countries once denuded of their past seek to assert their independent identities through the objects that tie them to it. The demand for restitution is a way to reclaim history, to assert a moral imperative over those who were once overlords. Those countries still in the shadow of more powerful empires seek to claim the symbols of antiquity and colonialism to burnish their own national mythmaking.
