The Sansis, by many accounts, have originated from the Bhati Rajputs. The clan’s history, however, is full of vicissitudes. Bhatis claim origin from Krishna’s clan. After their expulsion from Rajputana by Allaudin Khilji , the Sansis appeared as an offshoot of the vanquished Bhatis who took the title of the clan after Sans Mal, their consanguineous patriarch. The fortune and social standing of the clan underwent gradual deterioration from rulers to wandering gypsies and nomads , infamous in public perception as hunters , robbers and petty-thieves.
The fortune of a section of the clan dramatically changed for the better again after Budha Sansi , formerly a cattle-thief and robber, got baptized as a Sikh and joined forces with the rebellious Sikh militants who later on exploited the power vacuum in Punjab in the aftermath of Maratha-Afghan conflict to establish the independent Sikh Missals or confederacies. Nodh Singh and Chanda Singh, both Sansis and Budha Sansi’s sons, founded the powerful Sukarchakia Missal. Maharaja Ranjit Singh, the representative of Sukarchakia Missal, united all the missals to form the powerful Sikh kingdom which lasted around fifty years.
The rest of the clan was however not that fortunate and got notified as “Criminal Tribe” in the colonial era. The Sindhanwalias , the socially better off surviving Sansis, got allied with the Jats and a Sansi Jat clan was also recorded in early imperial censuses, which were rather crude and inaccurate. But the numbers of this “Jat” clan were extremely small , indicating it, at best, as a very recent accretion into an inclusive and a heterogeneous fold , which represents a functional category , composed of diverse farming identities, almost as often as it does an ethnic caste. Lepel Griffin , a contemporary of Maharaja, however, clearly identified as Sukerchakias as belonging to the same stock as rest of the Sansis, which is the same opinion held by many other historians of note.
