Minahasa is a prosperous Protestant region with a sizeable Muslim population, and other religious minorities in North Sulawesi province in Indonesia. It prides itself as the compass of religious tolerance. However, territorially distant from Java Island, as the center of Indonesian geopolitics, and vastly outnumbered by the majority Muslim population, the Christian Minahasans keep a guarded feeling toward Indonesian national center. Questioning and exploring the notion of nationhood by the Minahasans, this work engage with Adrian Hasting’s thesis in crediting religion and ethnicity to the foundation of nationalism (1997). Applying a qualitative approach, this study found that poly-ethnicity, religion and distinct historical and political background are the determining factors in the construction of nationhood as well as the sense of belonging of Minahasans to the larger Indonesian nationalism.
