Rai (title) in the context of "Zamindari system"

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.
