Q. Who was associated with Sanatan Adivasi Mahasabha?
Answer: Thebale Oraon
Notes: Thebale Oraon founded Sanatan Adivasi Mahasabha in July 1939. It split from Adivasi Mahasabha due to differences over Christian influence under Jaipal Singh Munda. The organization represented traditionalist tribals opposing separatism. Tilka Manjhi, Silu Santhal, and Dooka Ho were earlier tribal leaders with no affiliation to this group.
