The rituals makes human life colourful and cheerful along with the representation of richness of their cultural heritage. The cultural heritage differs from area to area and social groups. The chain of cultural heritage is very long and it includes the rituals of birth, marriage, death and festivals. Generally the occasion for marriage comes in only one time in once life period, so the prime importance have been give to this ritual. The marriage ceremony is bound with so many rituals between Sagai to Vidai. Keeping in view the importance of marriage I have tried to explore the marriage rituals of tribals and non-tribal groups of the country viz. Adikarnataka, Assamese, Hindus, Asur, Baurias, Bhils, Bhumija, Bhuyan, Birhor, Bohra, Christian, Damor, Ghasi, Gond, Hos, Saharia etc., in detail.
