The term "Bagri people" was originally applied to the Hindu Jats and Rajputs, such as Bagri Jat and Bagri Rajput, but now also applied to Bishnoi and one of the sections of Maheshwari Banias (traders), as well as Badhik ("butcher"), Pardhi ("hunter") and Bawariya (semi-nomads) castes. Prominent bagri people include was politician from Haryana Mani Ram Bagri (1 January 1920 – 31 March 2012, a politician from Haryana), Raj Bagri, Baron Bagri (24 August 1930 – 26 April 2017, India-born British businessman and a Conservative member of the House of Lords from 1997 to 2010, who was made a life peer in 1997).
"Bagri people" of the sandy dry "Bagar tract" speak the "Bagri language" (बागड़ी), a dialect of overlapping Rajasthani language, Haryanvi language and Punjabi language of the Indo-Aryan family, spoken by about five million speakers.
"Bagri region" or tract is long strip of shifting sand dunes called tibba (टिब्बा) and finer lands between them called lal (लाळ ) sandy tract in along the western border of Haryana and eastern border of Rajasthan.
The Bagar region has potentially very fertile alluvial soil interspersed with highly permeable very sandy tracts in several places with water table more than 100 feet below ground containing brackish water usually unfit for human consumption, where dust storms frequent during the warm summer months from April till the end of July when monsoon arrives. Previously the tract was solely based on the rain and irrigation was possible only in the small area of Bagar region in districts of Fatehabad, Sirsa, Hanumangarh and Sriganganagar where the season Ghaggar river flows. After the opening of Bhakra Nangal Dam canal system in 1963 as well as the earlier Western Yamuna Canal now irrigate most of Haryana including all of the Bagar region falling in Haryana on its western border. Opening of Indira Gandhi Canal in 1983 brought the water of Sutlej and Beas rivers to the fields of Rajasthan including its Bagar tract stabilizing the sand dunes and soil erosion by preventing the expansion of desert.
