The rich cultural heritage of the Kabui is reflected in their varieties of art. Racially or physically and linguistically Kabui are Tibeto-Burman (Indo-Mongoloid) of Sino-Tibetan family of the Mongolian race. Based on history it is assumed that Mongoloid groups including Kabui Naga were inhabiting the upper course of the Yangtze and Howang Ho rivers in China in the prehistoric times. The Kabui belongs to patriarchal social system. Each clan enjoys equal status. Clan exogamy is strictly observed. Cross-cousin marriage is most preferred but parallel cross-cousin is seldom. Besides following many other normal customs of a Naga-tribe, they also have some strange and fearful customs.
