Banavasi. In the west, it touched the Arabian Sea, and in the east, it included the western part of Andhra: Simhana's inscriptions have been discovered in the present-day Anantapur and Kurnool districts. Simhana consolidated the Yadava rule in the newly-annexed territories by posting his trusted lieutenants there. At his northern frontier, he assigned the fiefs of Khandesh and Vidarbha to his general Kholeshvara. At his southern frontier, he assigned the fief of southern Karnataka to his general Bichana. Kholeshvara was born to a Brahmin named Trivikrama, but adopted a warrior role, and defeated several small chiefs in the Vidarbha and Khandesh regions. These chiefs included Lakshmideva of Bhambhagiri (modern Bhamer), Hemadri of Khandesh, and Bhoja of Chanda (in present-day Madhya Pradesh). Since Kholeshvara came from a Brahmin family, he appears to have had a soft corner for the Brahmins, as suggest by his establishments of a number of agrahara (Brahmin settlements). Bichana, the son of Chikkadeva, was born in a Vaishya family. He played an important role in the anti-Hoysala campaigns, and one of his inscriptions claims that he advanced as far as the Kaveri River, where he set up a victory pillar. He succeeded Jagadala Purushottama-deva as Simhana's viceroy in the southern part of the Yadava kingdom, in 1230. Cultural activities The authorship of Sangita-ratnakara, a work on music, is attributed to Simhana's court poet Sharanga-deva. A commentary on this work is attributed to Simhana himself. It is not certain if Simhana actually wrote this commentary, or if he was the patron of its actual author. Simhana's courtiers included two noted astronomers: Anantadeva and Changadeva. Anantadeva wrote commentaries on Brahmagupta's Brahma-sphuta-siddhanta and Varahamihira's Brihat-jataka. Changadeva established a college of astronomy in Patana town of Khandesh region, in the memory of his grandfather Bhaskaracharya. Last days Simhana had two wives, named Jeha-devi and Kavala-devi. His son Jaitugi II (not to be confused with his father Jaitugi I) is known to have been the yuvaraja (heir apparent) in 1229, but he probably died before Simhana. Therefore, Simhana was succeeded by his grandson Krishna. According to A. S. Altekar, Krishna's inscriptions suggest that 2 November 1248 fell in the second year of his reign, while 25 December 1248 fell in the third year of his reign. Therefore, Altekar concludes that Simhana most probably died in either November of December 1246, when Krishna succeeded him. According to T. V. Mahalingam (1957), there are
