This article explores how museums in Taiwan represent a group, called Pingpu, whose indigenous status is highly contested. Pingpu specific cultural features have almost disappeared as a result of centuries of exchanges with Han Chinese settlers. As a consequence, Pingpu groups have not received official indigenous recognition by the Taiwanese government. Yet Pingpu groups are actively seeking recognition through public demonstrations and promoting public awareness of Pingpu concerns. The official recognition of Pingpu’s indigeneity is an ongoing, decades-long, controversial issue in Taiwan. Museums are one of the foci through which Pingpu issues are gaining visibility in Taiwan. But how are they dealing with this controversial issue? More broadly, what position can or should museums take in relation to contested indigenous claims to recognition? This article discusses recent exhibitions representing Pingpu at the light of the politics of representation of indigenous groups and the transformation of museums’ social roles in contemporary Taiwan.
