Deccan Plateau

The Deccan plateau (IPA: /dekən/) extends over an area of 422,000 km² (163,000 sq mi) on the southern part of the Indian peninsula. It stretches from the Satpura and Vindhya Ranges in the north to the northern fringes of Tamil Nadu in the south. It is bound by the mountain ranges of the Western Ghats and the Eastern Ghats on the sides, which separate the region from the Western and Eastern Coastal Plains respectively. It covers most of the Indian States of Maharashtra, Karnataka, Telangana and Andhra Pradesh excluding the coastal regions, and minor portions of Tamil Nadu and Kerala.

The plateau is marked by rocky terrain with an average elevation of about 600 m (2,000 ft). It is subdivided into Maharashtra Plateau, Karnataka Plateau, and Rayalaseema and Telangana Plateau. The Deccan Traps in the northwest were formed by multiple layers of igneous rock deposited by basaltic lava flows following a massive volcanic eruption occurred at the end of the Cretaceous period (66 mya). The underlying bed consists of granite and sedimentary rocks formed during the Precambrian era and the formation of Gondwana.

The region forms one of the major watersheds of India, with many perennial river systems such as Godavari, Krishna, and Kaveri flowing through the region. The plateau slopes gently from the west to east, resulting in most of the principal rivers flowing eastwards towards the Bay of Bengal. As the Western Ghats block the rain bearing winds, the plateau region is drier than the coastal region and has a semi-arid climate.

The Deccan plateau region was ruled by several kingdoms in Indian history such as Pallavas, Cholas, Pandyas, Satavahanas, Chalukyas, Rashtrakutas, Hoysalas, Kadambas, Kakatiyas, and Western Gangas. In the later medieval era, the lower plateau was ruled by the Vijayanagara empire, and the upper portion by the Bahmani kingdom, and its successors, the Deccan sultanates. It later housed the Kingdom of Mysore, Maratha confederacy, and Nizam's dominions. It was under the control of British Raj for nearly two centuries before Indian Independence in 1947. The Reorganisation of Indian states in the 1950s resulted in the creation of states on linguistic lines.

The word Deccan is an anglicised version of the Prakrit word dakkhaṇa, which evolved from the Sanskrit word dakṣiṇa, meaning "south".

Carbon dating shows that ash mounds associated with Neolithic cultures in region date back to 8000 BCE. Towards the beginning of 1000 BCE, iron technology spread through the region though geological evidence does not point to a fully developed Bronze Age in existence prior to the Iron Age. Since at least the 1st century BCE, the region was connected to the Silk Road and was involved in trade with the Mediterranean and East Asia.

Several dynasties such as the Pandyas of Madurai, the Cholas of Thanjavur, the Zamorins of Kozhikode, the Satavahanas of Amaravati, the Pallavas of Kanchi, the Kadambas of Banavasi, the Western Gangas of Kolar, the Rashtrakutas of Manyakheta, the Chalukyas of Badami, the Hoysalas of Belur, and the Kakatiyas of Orugallu ruled over the region from the 6th century BCE to the 14th century CE. In the Late Middle Ages, Vijayanagara empire conquered most of the southern part of the pleateu region. The upper portion was ruled by the Bahmani kingdom, and later by its successors, the Deccan sultanates.

The Europeans arrived in the 15th century CE and by the middle of the 18th century, the French and the British were involved in a protracted struggle for military control over the region. The Maratha Empire founded by Chatrapati Shivaji, briefly captured the region in the early 18th century CE. After the defeat of Mysore Kingdom in the late 18th century CE and the Vellore Mutiny in 1806 CE, the British East India Company consolidated their power over much of the region. The British Empire took control of the region from the British East India Company in 1857.
