The colonial ethnographies of Punjab recorded the gots of the landholding castes in great detail and the clan structures of the labouring and artisan communities barely at all.
Mazhabi, Ramdasia, Ravidasia, Ad-Dharmi, Valmiki, Bazigar, Sansi and the other Scheduled Caste communities of Punjab have their own clan names, marriage rules and origin traditions, and they are documented in a fraction of the detail applied to the Jat gots.
The Ad Dharm movement of the 1920s, led by Mangoo Ram Mugowalia of Mugowal in Hoshiarpur district, asserted that Punjab's Dalits were a separate original religion, not Hindus, and got Ad Dharmi recorded as a distinct category in the 1931 census. Around 400,000 people registered as such.
Mangoo Ram had been in the United States, was associated with the Ghadar Party, and came back to organise at home. That is the same route as many others in this period and it produced an entirely different politics.
Punjab has the highest Scheduled Caste population share of any Indian state and the least documented community history of any part of its population.
The Jat gots are recorded in the settlement reports because the settlement was about land and the Jats held it. The gots of the landless communities are not recorded in the same way.
Those communities have their own clan names, their own marriage rules and their own settlement histories, and almost none of it is in any document.
That gap is not accidental. A record made to establish who owns land will not record the people who own none, and everything written about Punjabi village society since has inherited the omission.
