The Manipuris (Meiteis) in Tripura have preserved a rich repertoire of rites and rituals which were practiced when they were in their motherland Manipur. These has been blending with local elements of Tripura transforming into a unique and dynamic cultural identity. The paper is an attempt to examine the life-cycle ceremonies of Manipuris (Meiteis) in Tripura particularly birth rituals that emphasize social cohesion. The findings indicate that while core Manipuris (Meiteis) rituals have been persevered, many have been adapted because of local influences promoting intercultural coexistence. It contributes to the understanding of cultural preservation, adaptation and transformation among migrant communities in Northeast India.
