The name of three major dynasties that ruled over large parts of central and southern India between the sixth and twelfth centuries CE. The Early Western Chalukyas were based in present-day northern Karnataka from the sixth to the eighth centuries CE, and a cadet branch, the Eastern Chalukyas, pruled in present-day coastal Andhra Pradesh from the seventh to the eleventh century. Another dynasty of the name, known as the Later Western Chalukyas, emerged as a major power in the Deccan from the late tenth to the twelfth century CE. All three dynasties are recognised for their patronage of art and architecture, and are associated with a number of significant cave and structural temples at Aihole, Badami and Pattadakal as well as in Kalyana (present-day Basavakalyan in northern Karnataka). Significant medieval texts such as the Gadayuddham of Ranna, the Vikramankadevacharitam of Bilhana, and the Manasollasa of Someshvara III were commissioned by the Later Western Chalukyas.
