Historical records, for example, state that the Jain leaders lobbied Mughal emperors to ban slaughter of cattles and other animals, during this 8 to 12 day period. In some cases, such as during the 16th century rule of Akbar, they were granted their request and an edict was issued by Akbar. Jahangir revoked the ban upon coronation, reinstated it in 1610 when Jain community approached and appealed to him, then later reversed the 1610 ban with a new edict.
