Marriage customs vary significantly across India's religious groups. For Hindus, which make up 83% of the population, marriage is considered a religious duty and parents arrange marriages between individuals of the same caste. Brides traditionally wear ornate saris and jewelry and weddings last 3 or more days. Dowries, where the bride's family provides property or wealth, were historically common but are now illegal. For India's Muslim and Sikh minorities, criteria like caste, chastity and maintaining family lineage are important in selecting spouses. Wedding customs incorporate religious rituals and community celebrations.
