Kayastha (also referred to as Kayasth or Kayeth) is a caste or community of Hindus originating in India. Kayasthas are considered to be members of the scribe caste, and have traditionally acted as keepers of public records and accounts, writers, and administrators of the state.
Kayasthas have historically occupied the highest government offices, serving as ministers and advisors during early medieval Indian kingdoms and the Mughal Empire, and holding important administrative positions during the British Raj.
In modern times, Kayasthas have attained success in politics, as well as in the arts and various professional fields.
According to the Hindu scriptures known as the Puranas, Kayasthas are descended from Chitragupta, "who was born from the body of Brahma", and is the deity responsible for recording the deeds of humanity, upholding the rule of law, and judging whether human beings go to heaven or hell upon death. Brahmanical religious texts refer to them as a caste of scribes, recruited in the beginning from the Brahmin, Kshatriya and Vaishya castes, but eventually forming distinct subcastes in northern and western India. Kayasthas have therefore also been mentioned as a "mixed caste", combining Brahman-Shudra (lower caste) and sometimes Kshatriya as well.
In eastern India, Bengali Kayasthas are believed to have evolved from a class of officials into a caste between the 5th/6th centuries and 11th/12th centuries, its component elements being putative Kshatriyas and mostly Brahmins, and likely obtained the aspect of a caste under the Sena dynasty. According to Tej Ram Sharma, an Indian historian, the Kayasthas of Bengal had not yet developed into a distinct caste during the reign of the Gupta Empire, although the office of the Kayasthas (scribes) had been instituted before the beginning of the period, as evidenced from the contemporary Smritis.
