A dynasty in that emerged in the Deccan region of southern India from the last quarter of the tenth century to the close of the twelfth century. The dynasty claimed descent from the Chalukyas of Vatapi (now Badami), who prevailed in the region from the sixth to the eighth centuries, and were initially feudatories of the early-medieval Rashtrakuta empire. The founder of this dynasty was Taila II, who overthrew the Rashtrakutas and consolidated his power in the region, establishing his capital at Kalyani (present-day Basavakalyana, Karnataka). The Western Chalukya dynasty was a contemporary and a rival of the Chola Empire. It was also related to the Eastern Chalukyas of Vengi (present-day Andhra Pradesh), who were feudatories of the Cholas.
