Deshastha Brahmin is a Hindu Brahmin subcaste mainly from the Indian state of Maharashtra and North Karnataka. Other than these states, according to authors K. S. Singh, Gregory Naik and Pran Nath Chopra, Deshastha Brahmins are also concentrated in the states of Telangana , Andhra Pradesh and Madhya Pradesh Historian Pran Nath Chopra and journalist Pritish Nandy say, "Most of the well-known saints from Maharashtra, Karnataka and Andhra Pradesh were Deshastha Brahmins". The mother tongue of Deshastha Brahmins is either Marathi, Kannada or Telugu. Over the millennia, the Deshastha community has produced Mathematicians such as Bhāskara II, Sanskrit scholars such as Bhavabhuti; Bhakti saints such as Dnyaneshwar, Sripadaraja, Eknath, Purandara Dasa, Samarth Ramdas and Vijaya Dasa; Logicians such as Jayatirtha and Vyasatirtha. The traditional occupation of Deshastha Brahmins is priesthood and the Kulkarni Vatan (village accountants). They also pursued secular professions such as writers, accountants, moneylenders and also practised agriculture. In historic times a large number of Deshasthas held many prominent positions such as Peshwa, Diwan, Deshpande (district accountants), Deshmukh, Patil, Gadkari, and Desai. Authors Vora and Glushkova state that "Deshastha Brahmins have occupied a core place in Maharashtrian politics, society and culture from almost the beginning of the Maharashtra's recorded history. Occupying high offices in the state and even other offices at various levels of administration, they were recipients of state honours and more importantly, land grants of various types." The word Deshastha derives from the Sanskrit deśa (inland, country) and stha (resident), literally translating to "residents of the country". The valleys of the Krishna and the Godavari rivers, and a part of Deccan plateau adjacent to the Western Ghats, are collectively termed the Desha – the original home of the Deshastha Brahmins. In Tamil Nadu, Deshastha Brahmins are also referred as Rayar Brahmins. The word Rayar means king in South India.
