Hoysala architecture is classified by the influential scholar Adam Hardy as part of the "Karnata Dravida" tradition, a trend within Dravidian architecture in the Deccan that is distinct from the Tamil style of further south. Other terms for the tradition are Vesara, and Chalukya architecture, divided into early Badami Chalukya architecture and the Western Chalukya architecture which immediately preceded the Hoysalas. The whole tradition covers a period of about seven centuries began in the 7th century under the patronage of the Chalukya dynasty of Badami, developed further under the Rashtrakutas of Manyakheta during the 9th and 10th centuries and the Western Chalukyas (or Later Chalukyas) of Basavakalyan in the 11th and 12th centuries. Its final development stage and transformation into an independent style was during the rule of the Hoysalas in the 12th and 13th centuries. Medieval inscriptions displayed prominently at temple locations give information about donations made toward the maintenance of the temple, details of consecration and on occasion, even architectural details.
