Familial structures in the Mahabharata era are a focus for historians seeking to comprehend social, political, and cultural dynamics. The epic outlines marriage, inheritance, and kinship rules, exemplified by "Niyoga," a practice allowing a widow to conceive via her deceased husband's brother. Notable instances include Draupadi's polyandrous union with the Pandavas and the influence of dharma on family ties, reflecting the era's social conventions.
