High Quality Content by WIKIPEDIA articles! A large body of Western Chalukya literature in Kannada was produced during the reign of the Western Chalukya Empire (973–1200 CE) in what is now southern India. This dynasty, which ruled most of the western Deccan in South India, is sometimes called the Kalyani Chalukya Dynasty, after its royal capital at Kalyani (now Basavakalyan), and sometimes called the Later Chalukya Dynasty for its theoretical relationship to the 6th-century Chalukya dynasty of Badami. For a brief period (1162–1183), the Kalachuris, a dynasty of kings who had earlier migrated to the Karnataka region from central India and served as vassals for several generations, exploited the growing weakness of their overlords and annexed the Kalyani. Around 1183, the last Chalukya scion, Somesvara IV, overthrew the Kalachuris to regain control of the royal city. But his efforts were in vain, as other prominent Chalukya vassals in the Deccan, the Hoysalas, the Kakatiyas and the Seunas destroyed the remnants of the Chalukya power.
