The Rengma Naga are a Tibeto-Burman ethnic group inhabiting the Northeast Indian states of Nagaland and Assam.[7] John Butler writes in 'Traves in Assam' on page number 121 that in 1839 Mr. Grange, Sub-Assistant Commissioner seems to have been the first European officer, who met the Rengma Naga in the vicinity of Mohung Dehooa, on his way to the Angami Hills.Mr. Sub-Assistant was deputed in December 1847, to enter the Rengma hills from Golaghat; but after visiting many villages, he found the country so heavy and impassable from the dense wet jungles and was forced to return to the plains at Kageerunga (sic).[8] "The Rengma Nagas" written by JP Mills, MA, Indian Civil Service, Honorary Director of Ethnography Assam in 1936 in Introductory part in page 2 states, "About a hundred years ago or more a body of the western Rengmas migrated north-west to the Mikir Hills, where they are still living."A man who has not been able to offer a great feast, or has never killed an enemy may wear an ordinary type of cloth called Rhikho.It is a dark blue cloth with a very broad median band, and embroidered with a thin zigzag pattern in red at the edges.
