Nepali is commonly classified within the Eastern Pahari group of the Northern zone of Indo-Aryan.The language originated from the Sinja Valley, Karnali Province then the capital city of the Khasa Kingdom around the 10th and 14th centuries. It developed proximity to a number of Indo-Aryan languages, most significantly to other Pahari languages. Nepali was originally spoken by the Khas people, an Indo-Aryan ethno-linguistic group native to the Himalayan region of South Asia. The earliest inscription in the Nepali language is believed to be an inscription in Dullu, Dailekh District which was written around the reign of King Bhupal Damupal around the year 981. The institutionalisation of the Nepali language arose during the rule of the Kingdom of Gorkha (later became known as the Kingdom of Nepal) in the 16th century. Over the centuries, different dialects of the Nepali language with distinct influences from Sanskrit, Maithili, Hindi, and Bengali are believed to have emerged across different regions of the current-day Nepal and Uttarakhand, making Nepali the lingua franca.
