According to the legends, Nanda Devi Raj Jat was started by Jagadguru Shankaracharya.
Historians have debated over it but the idols of Parvati, Bhagwati and Bhigneshwar found
in Dewal, Bedini and Kaila Binayak dating back from 8th to 10th Century AD and the
inscribed idol of Ganesh of 9th Century AD at Jyurangli clarify the tradition of
this kind of Yatra.
According to other records, Nanda Devi Raj Jat’s history dates back to 9th Century
AD when it was called Nanda Jat and celebrated each year at different places by the locals. Later on 15th Century AD, King Ajay Pal (Shesh Pal) of Chandragarhi combined all the Jats into one royal pilgrimage and started celebrating the farewell journey once in 12 years. Shesh Pal added the word Raj (royal) in Nanda Jat and announced the participation of royal family and royal priest in the journey. Since then the Yatra is organised by the successors of a royal family.
They offer tarpana (a ritual in Hinduism where food is offered to dead ancestors
as a remembrance and for spiritual peace) for their ancestor Yashodhawal, his pregnant
wife Vallavi, courtesan along with other his army.
