​​​The Khiamniungan tribe, living along the Indo–Myanmar border, is known for its rich warrior heritage and deep connection to the mountains of Noklak region. Historically, they were skilled in traditional defense practices and maintained strong village clans with clear social roles. Their lifestyle revolved around agriculture, hunting, and intricate rituals that guided seasonal activities. Though Christianity later reshaped many customs, their oral traditions, ancient craftsmanship, and community-based way of life continue to preserve the essence of their identity.

The Khiamniungan people believe strongly in courage, honesty, respect for elders, and maintaining peace within the community. Their worldview emphasizes living in harmony with nature, honoring ancestral wisdom, and upholding responsibility toward the village and family. Community cooperation and unity are considered essential virtues.

The tribe rejoices in the Tsokum festival, celebrated after harvest as an expression of gratitude for a successful agricultural season. It includes ritual offerings, community feasts, dances, and symbolic activities that strengthen social bonds. In earlier times, important ceremonies involved warrior rites, protective rituals for crops, and village purification practices led by elders.

The Khiamniungan tribe is recognized for their striking and elaborate traditional attire featuring bold contrasts of deep blue, black, and fiery red. Warrior costumes once included richly decorated headgear adorned with animal horns, dyed hairpieces, and feather ornaments symbolizing bravery. Women traditionally wear beautifully woven shawls with distinctive patterns and beadwork. Necklaces, armlets, and metal ornaments added meaning, often indicating social standing, achievements, or clan identity.

Key cultural symbols include traditional spears, daos (machetes), wooden shields, and ceremonial headgear once used during dances and warrior rituals. Intricate wood carvings, bamboo craftwork, and woven textiles also hold great significance, each pattern reflecting identity, beliefs, or historical events.
