The reputed founder, or rather reformer, of the sect was Basava (or Basaba), a Brahman of the Belgaum district who seems to have lived in the 11th or 12th century.
It is apparently the northern limit of what was once a vast basaltic plain stretching from Goona to Belgaum, "one of the most gigantic outpourings of volcanic matter in the world."
The twenty-six districts are: Bombay City, Ahmedabad, Broach, Kaira, Panch Mahals, Surat, Thana, Ahmednagar, Khandesh (partitioned into two districts in 1906), Nasik, Poona, Satara, Sholapur, Belgaum, Bijapur, Dharwar, Kanara, Kolaba, Ratnagiri, Karachi, Hyderabad, Shikarpur, Thar and Parkar, and Upper Sind Frontier.
It comprises the previous Poona district, Bombay district south of the Tapti, Belgaum district north of the Tungabhadra, and Dharwar and Aurungabad districts.
Baji Rao, the last of the peshwas, who had attempted to shake off the British yoke, was defeated, captured and pensioned-(1817-1818), and large portions of his dominions (Poona, Ahmednagar, Nasik, Sholapur, Belgaum, Kaladgi, Dharwar, &c.) were included in the presidency, the settlement of which was completed by Mountstuart Elphinstone, governor from 1819 to 1827.
