The Kalwar, Kalal or Kalar are an Indian caste historically found in Uttar Pradesh, Rajasthan, Punjab, Haryana, Jammu & Kashmir and other parts of north and central India.
[1] Because their hereditary occupation of distilling and selling liquor was considered degrading, the Kalals held a very low status in the traditional caste hierarchy of South Asia.
[2] Following Jassa Singh's rise, other Sikh Kalals also adopted Ahluwalia as the name of their caste, and started giving up their traditional occupation.
The regulations imposed by the colonial British administration on manufacture and sale of liquor accelerated this process, and by the early 20th century, most Kalals had abandoned their traditional occupation.
[2] Before the advent of the British rule, the Muslim Kalals also attempted to raise their social status by adopting the Kakezai Pashtun identity.
