Sultan Hasanuddin of South Sulawesi (1631-1670), Javanese Prince Diponegoro (1785-1855), and Teuku Umar of Aceh (1854-1899) were all acknowledged in 1973 by the Indonesian government as National Heroes for their resistance against the Dutch colonial power.1 This article discusses how their stories and belongings - exhibited in museums - intertwine with museum decolonization. The focus of this article relies on research in province museums in Makassar, Jakarta, and Banda Aceh. They were all established in colonial times and are all in some way related to the three heroes. These examples show how the decolonization of Indonesian museums is entangled with changing political regimes. © 2025, The Author(s).
