/dek"euhn/, n.1. the entire peninsula of India S of the Narbada River.2. a plateau region in S India between the Narbada and Krishna rivers.
* * *Peninsula of India south of the Narmada River.In a more restricted sense, it is the tableland between the Narmada and Krishna rivers, comprising Maharashtra and parts of Madhya Pradesh, Chhattisgarh, Orissa, Andhra Pradesh, and Karnataka. Its average elevation is about 2,000 ft (600 m). Its principal rivers, the Godavari, Krishna, and Kaveri, flow from the Western Ghats range eastward to the Bay of Bengal. Its early inhabitants were a Dravidian population not reached by the 2nd-millennium-BC Aryan invasion. Ruled by Mauryan (4th–2nd centuries BC) and Gupta (4th–6th centuries AD) dynasties, it became an independent Muslim kingdom in 1347. Later split up into five Muslim sultanates, the Deccan was largely conquered by the Mughal dynasty in the 17th century. In the 18th century it was the scene of rivalry between the British and French and subsequently of the British struggle against the Maratha confederacy. It remained under British control until India gained independence in 1947.
* * *the entire southern peninsula of India south of the Narmada River, marked centrally by a high triangular tableland. The name derives from the Sanskrit daksina (“south”). The plateau is bounded on the east and west by the Ghats, escarpments that meet at the plateau's southern tip. Its northern extremity is the Satpura Range. The Deccan's average elevation is about 2,000 feet (600 metres), sloping generally eastward. Its principal rivers—the Godavari (Godavari River), Krishna (Krishna River), and Kaveri (Kaveri River) (Cauvery)—flow from the Western Ghats eastward to the Bay of Bengal. The plateau's climate is drier than that on the coasts and is arid in places.The Deccan's early history is obscure. There is evidence of prehistoric human habitation; low rainfall must have made farming difficult until the introduction of irrigation. The plateau's mineral wealth led many lowland rulers, including those of the Mauryan (Mauryan empire) (4th–2nd century BCE) and Gupta (Gupta dynasty) (4th–6th century CE) dynasties, to fight over it. From the 6th to the 13th century, the Chalukya (Chalukya dynasty), Rastrakuta (Rāṣṭrakūṭa Dynasty), Later Chalukya, Hoysala (Hoysala dynasty), and Yadava (Yādava Dynasty) families successively established regional kingdoms in the Deccan, but they were continually in conflict with neighbouring states and recalcitrant feudatories. The later kingdoms also were subject to looting raids by the Muslim Delhi sultanate, which eventually gained control of the area.In 1347 the Muslim Bahmanī dynasty established an independent kingdom in the Deccan. The five Muslim states that succeeded the Bahmanī and divided its territory joined forces in 1565 at the Battle of Talikota (Tālikota, Battle of) to defeat Vijayanagar, the Hindu empire to the south. For most of their reigns, however, the five successor states formed shifting patterns of alliances in an effort to keep any one state from dominating the area and, from 1656, to fend off incursions by the Mughal Empire to the north. During the Mughal decline in the 18th century, the Marathas, the nizam of Hyderabad, and the Arcot nawab vied for control of the Deccan. Their rivalries, as well as conflicts over succession, led to the gradual absorption of the Deccan by the British. When India became independent in 1947, the princely state of Hyderabad resisted initially but joined the Indian union in 1948.
