Ujjainiya
The Ujjainiya (also spelled Ujjain and Ujjaini) are a Rajput clan that inhabits the state of Bihar.
The oral tradition of the Ujjaniya was written in the 19th century in a book called Tawarikh-i-Ujjaniya. According to this, they trace their ancestry to Ujjain where the Parmar Rajput kings ruled until their lands were over-run by tribal peoples. After settling in Bihar, the locals started to refer to them as Ujjainiya. They call themselves Ujjainiya Parmars.
