Kayastha in the context of Chitraguptavanshi Kayastha

A zamindar in the Indian subcontinent was an autonomous or semi-autonomous feudal lord of a zamindari (feudal estate). The term itself came into use during the Mughal Empire, when Persian was the official language; zamindar is the Persian for landowner. During the British Raj, the British began using it as a local synonym for "estate". Subsequently, it was widely and loosely used for any substantial landed magnates in the British India. Zamindars as a class were equivalent to lords and barons; in some cases, they were independent sovereign princes. Similarly, their holdings were typically hereditary and came with the right to collect taxes on behalf of imperial courts or for military purposes. This continued in states like Bihar, Haryana, Rajasthan, Uttar Pradesh, and West Bengal even after independence until the abolition of zamindari in 1950.

During the Mughal Empire, as well as the British rule, zamindars were the land-owning nobility of the Indian subcontinent and formed the ruling class. Emperor Akbar granted them mansabs and their ancestral domains were treated as jagirs. Most of the big zamindars belonged to the Hindu high-caste, usually Brahmin, Rajput, Bhumihar or Kayastha. During the colonial era, the Permanent Settlement consolidated what became known as the zamindari system. The British rewarded supportive zamindars by recognising them as princes. Many of the region's princely states were pre-colonial zamindar holdings elevated to a greater protocol. The British also reduced the land holdings of many pre-colonial princely states and chieftaincies, demoting their status to noble zamindars from previously higher ranks of royalty. During the period of British colonial rule in India, many wealthy and influential zamindars were bestowed with noble and royal titles such as Maharaja, Raja/Rai, Babu, Rai sahib, Rai Bahadur, Nawab and Khan.

Lohar or Lohra is considered to be a caste among Hindus and a clan among Muslims and Sikhs in the Indian states of Uttar Pradesh and Jharkhand, and in Nepal. They form traditionally artisanal castes. Writers of the British Raj period often used the term Lohara as a synonym for blacksmith, although there are other traditional smiting communities, such as the Ramgarhia and Sikligar, and numerous non-traditional communities, including the Kayastha, Rajput and Brahmin.

Khatri (IPA: [kʰət̪ɾiː]) is a caste originating from the Malwa and Majha areas of Punjab region of South Asia that is predominantly found in India, but also in Pakistan and Afghanistan. The Khatris claim they are warriors who took to trade. In the Indian subcontinent, they were mostly engaged in mercantile professions such as banking and trade. They were the dominant commercial and financial administration class of late-medieval India. Some in Punjab often belonged to hereditary agriculturalist land-holding lineages, while others were engaged in artisanal occupations such as silk production and weaving.

The Khatris of Punjab, specifically, were scribes and traders during the medieval period, with the Gurumukhi script used in writing the Punjabi language deriving from a standardised form of the Lāṇḍa script used by Khatri traders; the invention of the script is traditionally ascribed to Guru Angad. During the medieval period, with the rise of Persian as an elite vernacular due to Islamic rule, some of the traditional high status upper-caste literate elite such as the Khatris, Kashmiri Brahmins and Kayasthas took readily to learning Persian from the times of Sikandar Lodi onwards and found ready employment in the Imperial Services, specifically in the departments of accountancy (siyaq), draftsmanship (insha) and offices of the revenue minister (diwan).
