Godavari River in the context of "Dams"

South India, also known as Southern India or Peninsular India, is the southern part of the Deccan Peninsula in India encompassing the states of Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and Telangana as well as the union territories of Lakshadweep and Puducherry, occupying 19.31% of India's area (635,780 km or 245,480 sq mi) and 20% of India's population. It is bound by the Bay of Bengal in the east, the Arabian Sea in the west and the Indian Ocean in the south. The geography of the region is diverse, with two mountain ranges, the Western and Eastern Ghats, bordering the plateau heartland. The Godavari, Krishna, Kaveri, Penna, Tungabhadra and Vaigai rivers are important non-perennial sources of water. Chennai, Bengaluru, Hyderabad, Coimbatore and Kochi are the largest urban areas in the region.

The majority of the people in South India speak at least one of the four major Dravidian languages: Telugu, Tamil, Kannada and Malayalam. During its history, a number of dynastic kingdoms ruled over parts of South India, and shaped the culture in those regions. Major dynasties that were established in South India include the Cheras, Cholas, Pandyas, Pallavas, Satavahanas, Chalukyas, Hoysalas, Rashtrakutas and Vijayanagara. European countries entered India through Kerala and the region was colonized by Britain, Portugal and France.

Ujjain (/uːˈdʒeɪn/ , Hindi: [ʊd͡ːʒɛːn̪], Hindi: [əʋən̪t̪ɪkaː]), also known as Ujjayini, is a city in Ujjain district of the Indian state of Madhya Pradesh. It is the fifth-largest city in Madhya Pradesh by population and is the administrative as well as religious centre of Ujjain district and Ujjain division. It is one of the Hindu pilgrimage centres of Sapta Puri famous for the Kumbh Mela (Simhastha) held there every 12 years. The ancient and world famous temple of Mahakaleshwar Jyotirlinga is located in the center of the city. The city has been one of the most prominent trade and political centres of the Indian subcontinent from the time of the ancient Mahājanapadas until the British colonisation of India.

An ancient city situated on the eastern bank of the Shipra River, then known as Avantika,, it was the most prominent city on the Malwa plateau of central India for much of its history. It emerged as the political centre of central India around 600 BCE. It was the capital of the ancient Avanti kingdom, one of the sixteen Mahājanapadas. During the 18th century, the city briefly became the capital of the Scindia state of the Maratha Confederacy, when Ranoji Scindia established his capital at Ujjain in 1731. It remained an important political, commercial, and cultural centre of Central India until the early 19th century, when the British administrators decided to develop Indore as an alternative to it. Ujjain continues to be an important place of pilgrimage for Shaivites, Vaishnavites and Shaktas. Bathing in the holy Shipra river of Ujjain liberates one from sins. Therefore, Ujjain is also called the 'Mokshadayini city'. The name of this river is taken among the holy rivers like Kaveri, Narmada, Godavari and Krishna.

The Kaveri (also known as Cauvery, Tamil: [kɑːʋɪɾi]) is a major river flowing across Southern India. It is the third largest river in the region after Godavari and Krishna. The catchment area of the Kaveri basin is estimated to be 81,155 km (31,334 sq mi) and encompasses the states of Tamil Nadu, Karnataka, Kerala, and the union territory of Puducherry.

The river rises at Talakaveri in the Brahmagiri range in the Western Ghats. The source is located at an elevation of 1,341 m (4,400 ft) in the Kodagu district of Karnataka. The river flows for about 320 km (200 mi) through the Deccan Plateau in Karnataka before entering Tamil Nadu. It flows further eastward in Tamil Nadu for 416 km (258 mi) before flowing into the Bay of Bengal near Poompuhar in Mayiladuthurai district of Tamil Nadu. The river flows for a total length of about 800 km (500 mi). The major tributaries include Amaravati, Arkavati, Bhavani, Harangi, Hemavati, Kabini, Lakshmana Tirtha, Shimsha and Noyyal.

The Satpura Range (IPA: [sət̪pʊɽaː]), formerly also known as the Seeonee Hills, is a range of hills in central India. The range rises in eastern Gujarat running east through the border of Maharashtra and Madhya Pradesh and ends in Chhattisgarh. The range parallels the Vindhya Range to the north, and these two east–west ranges divide the Indian subcontinent into the Indo-Gangetic Plain of northern India and the Deccan Plateau of the south. The Narmada River originates from the north-eastern end of Satpura in Amarkantak, and runs in the depression between the Satpura and Vindhya ranges, draining the northern slope of the Satpura range, running west towards the Arabian Sea. The Tapti River originates in the eastern-central part of Satpura, crossing the range in the center and running west at the range's southern slopes before meeting the Arabian Sea at Surat, draining the central and southern slopes of the range. Multai, the place of Tapti river origin is located about 465 kilometer far, south-westerly to Amarkantak, separated across by the hill range. The Godavari River and its tributaries drain the Deccan Plateau, which lies south of the range, and the Mahanadi River drains the easternmost portion of the range. The Godavari and Mahanadi rivers flow into the Bay of Bengal. At its eastern end, the Satpura range meets the hills of the Chotanagpur Plateau. The Satpura Range is a horst mountain and is flanked by Narmada Graben in the north and the much smaller but parallel Tapi Graben in the south.

The Kakatiya dynasty (IAST: Kākatīya) was a Telugu dynasty that ruled most of eastern Deccan region in present-day India between 12th and 14th centuries. Their territory comprised much of the present day Telangana and Andhra Pradesh, and parts of eastern Karnataka, northern Tamil Nadu, and southern Odisha. Their capital was Orugallu, now known as Warangal.

Early Kakatiya rulers served as feudatories to Rashtrakutas and Western Chalukyas for more than two centuries. They assumed sovereignty under Prataparudra I in 1163 CE by suppressing other Chalukya subordinates in the Telangana region. Ganapati Deva (r. 1199–1262) significantly expanded Kakatiya lands during the 1230s and brought under Kakatiya control the Telugu-speaking lowland delta areas around the Godavari and Krishna rivers. Ganapati Deva was succeeded by Rudrama Devi (r. 1262–1289) who is one of the few queens in Indian history. Marco Polo, who visited India around 1289–1293, made note of Rudrama Devi's rule and nature in flattering terms. She successfully repelled the attacks of Yadavas (Seuna) of Devagiri into the Kakatiyan territory.

Mir Osman Ali Khan, Asaf Jah VII (5 or 6 April 1886 – 24 February 1967) was the last Nizam (ruler) of Hyderabad State, the largest state in the erstwhile Indian Empire. He ascended the throne on 29 August 1911, at the age of 25 and ruled the State of Hyderabad between until 1948, when the Indian Union annexed it. He was styled as His Exalted Highness (H.E.H) the Nizam of Hyderabad, and was widely considered one of the world's wealthiest people of all time. With some estimates placing his wealth at 2% of U.S. GDP, his portrait was on the cover of Time magazine in 1937. As a semi-autonomous monarch, he had his mint, printing his currency, the Hyderabadi rupee, and had a private treasury that was said to contain £100 million in gold and silver bullion, and a further £400 million of jewels (in 2008 terms). The major source of his wealth was the Golconda mines, the only supplier of diamonds in the world at that time. Among them was the Jacob Diamond, valued at some £50 million (in 2008 terms), and used by the Nizam as a paperweight.

During his 37-year rule, electricity was introduced, and railways, roads, and airports were developed. He was known as the "Architect of modern Hyderabad" and is credited with establishing many public institutions in the city of Hyderabad, including Osmania University, Osmania General Hospital, State Bank of Hyderabad, Begumpet Airport, and the Hyderabad High Court. Two reservoirs, Osman Sagar and Himayat Sagar, were built during his reign, to prevent future flooding after the Great Musi Flood of 1908 in the city. The Nizam also constructed the Nizam Sagar Dam and, in 1923, a reservoir was constructed across the Manjira River, a tributary of the Godavari River, between Achampet (Nizamabad) and Banjepally villages of Kamareddy district in Telangana, India. It is located at about 144 km (89 mi) northwest of Hyderabad and is the oldest dam in the state.
