Sport is not merely a recreational activity; it is a powerful cultural practice that reflects and reinforces social values, historical memory, and collective identity. Among the Mizo people of north-east India, both traditional and modern sports serve as profound expressions of cultural continuity, adaptability, and identity formation. This paper examines how indigenous Mizo sports and the adoption of modern games shape Mizo identity in the face of changing socio-cultural dynamics, with particular attention to gender, generational shifts, and the role of sport in fostering communal cohesion.
