The Ol Onal script was created in between 1981 and 1992 by Mahendra Nath Sardar for the Bhumij language. The Bhumij community had no written language, and knowledge was transmitted orally from one generation to another. Later researchers started to use Devanagari, Bengali, and Odia scripts to document the Bhumij language. However, Bhumijs did not have their own script. Sardar's invention of the Ol Onal script enriched the cultural identity of the tribal Bhumij community. He wrote many text books in the Ol Onal script. Language
