It is the seventh-largest state by area covering an area of 162,975 km2 (62,925 sq mi) and tenth-most populous state with 49,386,799 inhabitants,. It is bordered by Telangana to the north-west, Chhattisgarh to the north, Odisha to the north-east, Tamil Nadu to the south, Karnataka to the west and the Bay of Bengal to the east. It has the second longest coastline in India after Gujarat, of about 974 km (605 mi). Andhra Pradesh was the first state to be formed on a linguistic basis in India on 1 October 1953. On 1 November 1956, Andhra State was merged with the Telugu-speaking areas of the Hyderabad State to form Andhra Pradesh. Amaravati serves as the capital with the largest city being Visakhapatnam.Andhra Pradesh was once a major Buddhist pilgrimage site in the country and a Buddhist learning center which can be seen in many sites in the state in the form of monastery ruins, chaityas and stupas. It is also known for being the land of Koh-i-Noor and other globally known diamonds from Kollur Mine. It is also a major producer of rice known as the "Rice bowl of India". Its official language is Telugu; one of the classical languages of India, the fourth most spoken language in India and the 13th-most spoken language in the world. Andhra Pradesh's second official language is Urdu.Early inhabitants were known as the Andhras, tracing their history back to the Vedic period, when they were mentioned in the 8th century BCE Rigvedic text Aitareya Brahmana. According to the Aitareya Brahmana, the Andhras left North India from the banks of the Yamuna river and migrated to South India. The Assaka Mahajanapada (700–300 BCE) was an ancient kingdom located between the Godavari and Krishna rivers in southeastern India. Accounts that people in the region are descended from the Viswamitra are found in the Ramayana, the Mahabharata and the Puranas. The region also derives its name from the Satavahanas, who are also known as Andhras, the earliest kings of Andhra Pradesh and India.People of the said era supported local art and culture by building temples and sculptures of the Buddhist monuments in the state. It was ruled by the Mauryan Empire, Satavahana dynasty, Salankayanas, Andhra Ikshvakus, Pallavas, Vishnukundinas, Eastern Chalukyas, Rashtrakutas, Cholas, Kakatiyas, Vijayanagara Empire, Gajapati Empire, Mughal Empire, Deccan sultanates, Qutb Shahi dynasty, and Asaf Jahis. In the 3rd century BCE, Andhra was a vassal kingdom of Ashoka, but after his death Andhra became powerful and extended its empire to the whole of Maratha country and beyond.Andhra Pradesh comprises three major regions namely Rayalaseema in the south-west, Coastal Andhra bordering the Bay of Bengal in the east and Uttarandhra at north-east. The state has 26 districts, 6 in Uttarandhra, 12 in Coastal Andhra and 8 in Rayalaseema. The state also borders a union territory, Yanam – a district of Puducherry, which lies to the south of Kakinada in the Godavari delta on the eastern side of the state. The economy of Andhra Pradesh is the 8th largest in India, with a gross state domestic product (GSDP) of ₹8.84 trillion (US$110 billion) and has the country's 17th-highest GSDP per capita of ₹170,000 (US$2,100). Andhra Pradesh ranks 27th among Indian states in Human Development Index (HDI). It has a jurisdiction over almost 15,000 square kilometres (5,800 sq mi) of territorial waters.Andhra Pradesh hosted 121.8 million visitors in 2015, a 30% growth in tourist arrivals over the previous year, making it the third most-visited state in India. The Tirumala Venkateswara Temple in Tirupati is one of the world's most visited religious sites, with 18.25 million visitors per year. The region is also home to a variety of other pilgrimage centres, such as the Pancharama Kshetras, Mallikarjuna Jyotirlinga and Kodanda Rama Temple. The state's natural attractions include the beaches of Visakhapatnam, hill stations such as the Araku Valley and Horsley Hills, and the deltas of Konaseema in the Godavari river, and Diviseema in the Krishna river.

Delhi, officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. Straddling the Yamuna river, primarily its western or right bank, Delhi shares borders with the state of Uttar Pradesh in the east and with the state of Haryana in the remaining directions. The NCT covers an area of 1,484 square kilometres (573 sq mi). According to the 2011 census, Delhi's city proper population was over 11 million, while the NCT's population was about 16.8 million. Delhi's urban agglomeration, which includes the satellite cities of Ghaziabad, Faridabad, Gurgaon and Noida in an area known as the National Capital Region (NCR), has an estimated population of over 28 million, making it the largest metropolitan area in India and the second-largest in the world (after Tokyo).The topography of the medieval fort Purana Qila on the banks of the river Yamuna matches the literary description of the citadel Indraprastha in the Sanskrit epic Mahabharata; however, excavations in the area have revealed no signs of an ancient built environment. From the early 13th century until the mid-19th century, Delhi was the capital of two major empires, the Delhi sultanate and the Mughal Empire, which covered large parts of South Asia. All three UNESCO World Heritage Sites in the city, the Qutub Minar, Humayun's Tomb, and the Red Fort, belong to this period. Delhi was the early centre of Sufism and Qawwali music. The names of Nizamuddin Auliya and Amir Khusrau are prominently associated with it. The Khariboli dialect of Delhi was part of a linguistic development that gave rise to the literature of the Urdu language and then of Modern Standard Hindi. Major Urdu poets from Delhi include Mir Taqi Mir and Mirza Ghalib. Delhi was a major centre of the Indian Rebellion of 1857. In 1911, New Delhi, a southern region within Delhi, became the capital of the British Indian Empire. During the Partition of India in 1947, Delhi was transformed from a Mughal city to a Punjabi one, losing two-thirds of its Muslim residents, in part due to the pressure brought to bear by arriving Hindu refugees from western Punjab. After independence in 1947, New Delhi continued as the capital of the Dominion of India, and after 1950 of the Republic of India. Delhi ranks fifth among the Indian states and union territories in human development index. Delhi has the second-highest GDP per capita in India (after Goa). Although a union territory, the political administration of the NCT of Delhi today more closely resembles that of a state of India, with its own legislature, high court and an executive council of ministers headed by a Chief Minister. New Delhi is jointly administered by the federal government of India and the local government of Delhi, and serves as the capital of the nation as well as the NCT of Delhi. Delhi is also the centre of the National Capital Region, which is an "interstate regional planning" area created in 1985. Delhi hosted the inaugural 1951 Asian Games, the 1982 Asian Games, the 1983 Non-Aligned Movement summit, the 2010 Men's Hockey World Cup, the 2010 Commonwealth Games, and the 2012 BRICS summit and was one of the major host cities of the 2011 Cricket World Cup.
