Legend has it that the Mehrat, Kathat and Cheeta communities - with a combined total of one million people in four districts of central Rajasthan - are the descendants of the Hindu ruler of the warrior caste, Prithviraj Chauhan.
The three communities also have strong Islamic connections, because many centuries ago, their forefathers undertook a pledge to follow three Muslim practices.
These include the circumcision for the newborn male children in the community, eating halal meat and burying their dead.
That is the tradition many have followed, keeping the word of their ancestors. But it has also led to them facing something of a faith-based identity crisis.
