Among the most ancient clans in their region, the Pals trace their descent from a branch of the imperial Pala dynasty of Bengal, claiming Mahipala I as their ancestor, though it is not possible to ascertain the accuracy of this.

[4] One younger son, Pratap Chandra Pal, converted to Islam under the name "Prachanda Khan" and established his own separate territory, with his heirs becoming prominent landowners themselves; among his descendants are the Muslim Chowdhurys of Kala and Bahadurpur, also in Beanibazar.

[4] The latter's son, Krishna Kishore Pal Chowdhury, founded the Bihani Bazar (Morning Market), from which the town of Beanibazar (now expanded into the sub-district) derives its name.
