The Bais is a Rajput clan from India.
History
Their wealth caused Donald Butter, a visiting doctor who wrote Outlines of the Topography and Statistics of the Southern Districts of Oudh, and of the Cantonment of Sultanpur-Oudh, to describe the Bais Rajput in the 1830s as the “best dressed and housed people of the southern Oudh“.
The Bais Rajputs were known for well-building.
