Definition
The large triangular tableland that forms most of peninsular India south of the Satpura and Vindhya ranges, bounded by the Western Ghats on the west and the Eastern Ghats on the east, tilting gently eastwards so that most of its rivers drain into the Bay of Bengal.
Background and evolution
The name comes from the Sanskrit dakshina, meaning south, and for most of Indian history "the Deccan" meant the lands beyond the Narmada, a region with its own kingdoms, languages and trade routes. Satavahanas, Chalukyas, Rashtrakutas, the Bahmani sultanate, Vijayanagara and later the Marathas and the Nizams built states on this tableland, and its fortified hilltops and river valleys shaped warfare and administration.
This page treats the plateau as a working region rather than as a volcanic landform. In physical terms it is one of the oldest and most stable parts of the Indian landmass, made largely of ancient crystalline rocks, gneisses and granites, overlain in the north-west by thick sheets of lava basalt. Long erosion has worn it down to rolling uplands with flat-topped hills, isolated rocky knobs called tors, broad shallow valleys and occasional steep scarps. Because the western edge is raised, the drainage runs east: the Godavari, Krishna and Kaveri rise close to the Arabian Sea yet travel across the whole peninsula.
