This study critically examines the transformation of marriage practices in Mizo society, highlighting the shift from clan-based, customary institutions to individual-oriented unions shaped by modernization, education, religion, and law. Traditionally, Mizo marriage was rooted in clan exogamy, bride price (manpui), and the authority of elders, functioning as both a social and economic institution that reinforced kinship and cultural continuity. Women’s roles were historically restricted under patriarchal norms, with marriages arranged primarily to consolidate family and clan alliances. However, with the advent of Christianity, urbanization, and modern education, significant changes emerged. Church solemnization replaced clan ceremonies, bride price became symbolic, and gender roles underwent redefinition with greater autonomy and rights for women. Present-day marriages are increasingly based on love and personal choice, with families serving advisory rather than controlling roles. Legal recognition under civil law further ensures equality and protection in marital relations. Despite modernization, elements of tradition such as clan exogamy and symbolic bride price persist, reflecting cultural continuity. This synthesis of tradition and modernity demonstrates how Mizo society adapts to preserve its heritage while embracing progressive values of equality, freedom, and personal choice. The findings affirm that marriage remains a vital cultural institution, evolving to balance historical practices with contemporary aspirations
