Religion in Arunachal Pradesh
Owing to its ethnic and cultural diversity, religion in Arunachal Pradesh has been a spot for the syncretism of different traditional religions. Much of the native Tani populations follow an indigenous belief which has been systematised under the banner "Donyi-Polo" (Sun-Moon) since the spread of Christianity in the region by Christian missionaries in the second half of the 20th century.
