The Minahasans or Minahassa are an indigenous ethnic group from the North Sulawesi province of Indonesia, formerly known as North Celebes. The Minahasa people sometimes refer to themselves as Manado people. Although the Minahasan pre-Christian creation myth entails some form of ethnic unification, before the nineteenth century the Minahasa region was in no way unified. Instead, a number of politically independent groups (walak) existed together, often in a permanent state of conflict.
