In fact, the word 'Chutiya' that we use ( in India ) so easily as abuse for anyone, is not an avei. You will be surprised to know that there is a tribal tribe in Assam, named 'Chutia' and 'Sutiya' and these people are also known as 'Chutia People'. There are people from a community living in Assam, descendants of the Sino-Tibetan family of Mongoloid stock.
Actually, the history of 'Chutia' is recorded in the Assamese Chronicle of Assam. The 'Assamese Chronicle' is named after Assambhina, a 'Chutia King' who lived on the banks of the Brahmaputra River in the early seventh century.
During that period, people of 'Chutia' dynasty formed their empire in Assam and Arunachal Pradesh and ruled there from 1187 to 1673.
It is believed that this group living in Assam is the first group whose people migrated from southern China (present-day Tibet and Sichuan). Earlier these people spoke a language of Tibeto-Burman origin, but gradually they started speaking Assamese with the adoption of Hinduism.
The Chutia community is recognized by the Government of India as OBC. And this is the only tribal community in Assamese speaking India. At the same time, according to the 2011 census report, their estimated population was about 26 lakhs.
Historians believe that the word 'Chutia' originated from 'Chut', 'Chut' or "mountain top".
