inhabit central, eastern, northern India, and particularly Bengal. They are considered a Forward Caste, as they do not qualify for any of the reservation benefits allotted to Scheduled Castes and Scheduled Tribes and Other Backward Classes that are administered by the Government of India. This classification has increasingly led to feelings of unease and resentment among the Kayasthas, who believe that the communities that benefit from reservation are gaining political power and employment opportunities at their expense. Thus, particularly since the 1990 report of the Mandal Commission on reservation, Kayastha organisations have been active in areas such as Bihar, Madhya Pradesh, Bengal and Orissa. These groups are aligning themselves with various political parties to gain political and economic advantages; by 2009 they were demanding 33 percent reservation in government jobs. Sub-groups Chitraguptavanshi Kayasthas The Chitraguptavanshi Kayasthas of Northern India are named thus because they have a myth of origin that says they descend from the 12 sons of the Hindu god Chitragupta, the product of his marriages to Devi Shobhavati and Devi Nandini. The suffix -vanshi is Sanskrit and translates as belonging to a particular family dynasty. At least some Chitraguptavanshi subcastes seem to have formed by the 11th or 12th century, evidenced by various names being used to describe them in inscriptions. Although at that time, prior to the Muslim conquests in the Indian subcontinent, they were generally outnumbered by Brahmins in the Hindu royal courts of northern India, some among these Kayasthas wrote eulogies for the kings. Of the various regional Kayastha communities it was those of north India who remained most aligned to their role of scribes, whereas in other areas there became more emphasis on commerce. The group of Bhatnagar, Srivastava, Ambashtha and Saxena of Doab were classified by various Indian, British and missionary observers to be the most learned and dominant of the "service castes". Bengali Kayasthas 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. They most likely gained the characteristics 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 Kayastha (scribe) had been instituted before the beginning of
