Ramraiyas follow Baba Ram Rai, the excommunicated eldest son of Guru Har Rai (1630–61), who was sent by his father as an emissary to the Mughal court at Delhi. He won the approval of the emperor Aurangzeb but the displeasure of his own father, by changing lines of Guru Granth Saahib, who when choosing the next Sikh Guru passed over Baba Ram Rai and selected his younger brother Har Krishan. A few Baba Ram Raiya institutions are maintained in Dehra Dun ( Uttarakhand state) on land given to Baba Ram Rai by Aurangzeb.
