The Kosli language movement has been campaigning for recognition for the Kosli language. This movement has been going on for the last five decades in the districts of Western Odisha or Kosal. Persons like Prayag Dutta Joshi, Nilamadhab Panigrahi and others started this movement.
According to some, the Kosli language is considered a dialect of the Oriya language. In the Census of India- 2001, the Kosli language is shown as a mother tongue grouped under Oriya. There are several radio and TV programmes in the Kosli language.
The main objective of this movement is to include the Kosli language in the 8th schedule of the Indian constitution.
Kosal Discussion and Development Forum (KDDF), an organization working for the development of the Kosli speaking region, submitted in 2011 a memorandum to then Prime Minister Manmohan Singh. The memorandum stated that recently the Union government passed the 93rd Constitutional Amendment that enabled the inclusion of four languages viz. Bodo, Dogri, Santhali, and Maithili in the 8th Schedule. "We the people of Western Odisha were hoping that Kosli be included as well because our situation is identical to that of Maithili".
