Dadri mela is an annual festival celebrated in Dadri, Ballia district of Uttar Pradesh. It is believed to have been started 5000 years ago[1] and is currently organized by the Balia Municipal Corporation. The mela is associated with Hindu rishi Bhrigu and is named after his student rishi Dadar. it is believed to be started after the joining of Sarju and Ganga by rishi Dadar. The mela is held for one month in two phases, first phase is 10 days before Kartika Purnima and is the Second Largest Market for cattle and animal trade.[2] The second phase is started on Kartika Purnima with evening Maha aarti.
According to Pauranic legends, when Rishi Bhrigu attacked Vishnu, he felt great remorse. To repent for his sins, he came back to Earth and started Prāyaścitta. During this time, due to his mastery in Jyotish Shastra, he learned that the river Ganga was going to dry up in the future. To prevent this, he asked his student, Rishi Dardr, to merge the Sarayu and Ganga rivers. Obeying his teacher's command, Rishi Dardr did so. The people at the confluence of the two rivers were overjoyed and celebrated the day as a festival. Since then, the mela has been celebrated annually.
The mela is believed to have started in Pauranic times and is often believed to be 5000 years old.[3] it has been celebrated at the same place but the animal fair and meena bazar were added later possibly during Mughal king Akbar's time.
