The Calukyas of Badami formed the dynasty of the Deccan from the middle of the 6th century to the first half of the 8th century. In this paper, the author examines the administrative division called visaya under that dynasty, using inscriptions as source materials. The characteristics of visayas are : 1)There were many visayas in the domains of provincial rulers, whose control was allowed to continue through subservience to the Calukyas. 2)In the dynastic records, besides the strict meaning of administrative division, visaya also meant generally area or territory. 3)Since there was no unified official system of visaya administration, it would be difficult to regard it as a complete organization for political integration within dynasty territories. Even though the central government undertook to spread its control over provincially ruled territories by setting up visayas, these division could not always have functioned, at least in the territories of provincial rules, as arms of a centralized integrative force.
