The Tolong Siki alphabet was devised by Dr Narayan Oraon, a doctor from Jharkhand, with assistance from Francis Ekka, the former director of the Central Institute of Indian Languages (CIIL) in Mysore; Ramdayal Munda, the former Vice Chancellor of Ranchi University; and Nirmal Minz.
In 1989 Dr Oraon decided to create a new script for his native language, Kurukh, which is usually written with the Devanagari alphabet. His alphabet was published on 15th May 1999, and introduced into some schools later that year. It was formally recognised by the government of Jharkhand in 2007.
Tolong Siki is now promoted by the Kurukh Literary Society, and quite a few books and magazines have been published in it. It also taught in a number of schools.
Kurukh (कुड़ुख़), a Dravidian language spoken mainly in the Indian state of Orissa, and also in Bihar, Jharkhand, Madhya Pradesh, Chhattisgarh and West Bengal, by about two million people. There are also some Kurukh speakers in Bangladesh, Nepal and Bhutan. Kurukh, which is also known as Uraon, Kurux, Kunrukh, Kunna, Urang, Morva and Birhor, is closely related to Brahui and Malto.
