Listing some of the empires which were based out of Deccan...
Satavahana was the first large kingdom of central India. It probably came to power at the end of the third or beginning of the second century BCE (it’s not known exactly when), as one of the major successor states to the great Mauryan empire. It was based in the great plateau of the Deccan.
Not for long, however. By the end of the third century a new dynasty had established its sway over much of the Deccan. This was the Vakataka dynasty.
One of these was ruled by a dynasty called the Chalukya. This expanded its borders in the second half of the 6th century and first half of the 7th century to form a large empire covering much of central India.
The dynasty survived until 753, when one of its feudatories seized power and installed a new dynasty on the throne. This was the Rashtrakuta dynasty.
The Western Chalukya
The Rashtrakutas fell from power in 973 when a surviving member of the old Chalukya ruling family seized the throne. Once again a powerful Chalukya kingdom covered much of the Deccan. It would never be as powerful as either the former Chalukya empire or the Rashtakuta empire had been, and its territories were more or less confined to the western Deccan – hence its name, the Western Chalukya kingdom.
