Rambu Solo’ is a funerary ritual practiced by the Toraja people of Sulawesi, Indonesia, where death is understood as a gradual process rather than a single event. The deceased may remain within the household for extended periods before the funeral takes place, treated as part of daily life until the ceremony is held.

The funeral unfolds over several days and involves the gathering of extended family and community members. Central to the ritual are the sacrifice of water buffalo and pigs, offerings that hold both spiritual and social significance and are associated with the status of the deceased. The ceremonies also include processions, traditional dances and communal meals shared among participants.

Buffalo play a key role within Toraja cosmology, believed to assist the soul in its journey to the afterlife. The scale of the ceremony reflects both social ties and obligations, with families often preparing for years to organize the event.
