Marapu

The Marapu religion (also known as Marafu in Sumba) is a form of ancestral religion that is practiced mainly in the island of Sumba in Indonesia. Marapu is also practiced in many more remote areas of Sumba and Flores. Both the Christians and Muslims on these islands tend to combine their faiths with Marapu. Since Marapu, like Kaharingan of the Dayaks, is not an official religion of Indonesia, and all Indonesian citizens are required to identify as a member of one of the religions sanctioned by law, members have chosen either Christianity or Islam to self identify.
