The earliest historical evidence of settlement of Brahmins in Assam comes from various epigraphic sources of the
Varman dynasty (350–650). In the late medieval period beginning with the early 16th century, a number of Brahmins from
Mithila,
Benaras,
Kanauj,
Bengal and
Puri (Srikshetra), were settled in western Assam by the
Koch kings for performing Brahminical rites. During the reign of
Nara Narayan (1554-1587) of the
Koch dynasty, two Brahmins named Siddhantavagisa and Vidyavagisa were brought from
Gauda and Siddhantavagisa was responsible for the spread of Hinduism in the Koch kingdom Even during the reign of Koch king Prannarayana (1633-1655), Brahmins were brought from Mithilia to serve in the Koch kingdom and this process was later continued by the
Ahom state especially under the
Tungkhungia Ahom kings with
Siva Singha donating 19 out of the 48 landgrants by the Ahom kings to Brahmins. The migration of Brahmins into Assam took place from Central
Himalayas as well. Most of these migration took place due to the foreign invasions in
North India and on the invitation by the local rulers. Traditionally these Brahmins held the highest positions in society. == Tradition and culture==
