The Western Chalukya Empire ruled most of the western Deccan, South India, between the 10th and 12th centuries. This Kannadiga 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 6th-century Chalukya dynasty of Badami. The dynasty is called Western Chalukyas to differentiate from the contemporaneous Eastern Chalukyas of Vengi, a separate dynasty.
