Oriya language
An avid scholar of History, Shri Dubey's historical researches find mention in several historical books and treatises like "Dakshin Kosal Ka Prachin Itihas"PREVIEW by Dr. P.L.Diwan. His article "The politics of Language" traces the history of the Oriya language that Oriya was planted as the spoken language of Sambalpur and Kalahandi districts in the Records of British Government. Subsequently, Sambalpuri speaking regions were claimed as Oriya speaking regions. This sounded the death knell for the centuries-old Kosal state being eclipsed and ruled by the Oriya speaking people.
