The Western Chalukya Empire (Kannada:ಪಶ್ಚಿಮ ಚಾಲುಕ್ಯ ಸಾಮ್ರಾಜ್ಯ) ruled most of the western Deccan, South India, between the 10th and 12th centuries. This dynasty is sometimes called the Kalyani Chalukya after its regal capital at Kalyani, today's Basavakalyan in Karnataka and alternatively the Later Chalukya from its theoretical relationship to the sixth century Chalukya dynasty of Badami. The dynasty is called Western Chalukyas to differentiate from the contemporaneous Eastern Chalukyas of Vengi, a separate dynasty. Prior to the rise of these Chalukyas, the Rashtrakuta empire of Manyakheta controlled most of deccan and central India for over two centuries. In 973, seeing confusion in the Rashtrakuta empire after a successful invasion of their capital by the Paramara of Malwa, Tailapa II a feudatory of the Rashtrakuta ruling from Bijapur region defeated his overlords and made Manyakheta his capital. The dynasty quickly rose to power and grew into an empire under Somesvara I who moved the capital to Kalyani.
For over a century, the two empires of southern India, the Western Chalukyas and the Chola dynasty of Tanjore fought many fierce wars to control the fertile region of Vengi. During these conflicts, the Eastern Chalukyas of Vengi, distant cousins of the Western Chalukyas but related to the Cholas by marriage took sides with the Cholas further complicating the situation.[1][2][3][4] Vast areas between the Narmada River in the north and Kaveri River in the south came under Chalukya control. During this period the other major ruling families of the Deccan, the Hoysalas, the Seuna Yadavas of Devagiri, the Kakatiya dynasty and the Southern Kalachuri, were subordinates of the Western Chalukyas and gained their independence only when the power of the Chalukya waned during the later half of the twelfth century.
The Western Chalukyas developed an architectural style known today as a transitional style, an architectural link between the style of the early Chalukya dynasty and that of the later Hoysala empire. Most of its monuments are in the districts bordering the Tungabhadra River in central Karnataka. Well known examples are the Kasivisvesvara Temple at Lakkundi, the Mallikarjuna Temple at Kuruvatii, the Kallesvara Temple at Bagali and the Mahadeva Temple at Itagi. This was an important period in the development of fine arts in Southern India, especially in literature as the Western Chalukya kings encouraged writers in the native language of Kannada, and Sanskrit.
