Explanation:

The Munda people are an Austroasiatic speaking ethnic group of India. They predominantly speak the Mundari language as their native language, which belongs to the Munda subgroup of Austroasiatic languages. The Munda are found in the northern areas of east India concentrated in the states of Jharkhand, Bihar, Odisha and West Bengal.According to R. S. Sharma, a historian of ancient and early medieval India, pre-Aryan tribals who spoke the Munda language occupied the eastern region of ancient India. Many Munda terms occur in Vedic texts believed to have been written between 1500 BCE and 500 BCE. Their presence in texts compiled in the upper Gangetic basin late in that period suggests that Munda speakers were there at the time. According to Barbara A. West, the Mundas claim origin in Uttar Pradesh, and a steady flow eastward in history as other groups moved into their original homeland. They inhabited a much larger territory in ancient India.
