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.

Aurangabad (pronunciation ,is a city in the Indian state of Maharashtra. It is the administrative headquarters of Aurangabad district and is the largest city in the Marathwada region. Located on a hilly upland terrain in the Deccan Traps, Aurangabad is the fifth-most populous urban area in Maharashtra with a population of 1,175,116. The city is known as a major production center of cotton textile and artistic silk fabrics. Several prominent educational institutions, including Dr. Babasaheb Ambedkar Marathwada University, are located in the city. The city is also a popular tourism hub, with tourist destinations like the Ajanta and Ellora caves lying on its outskirts, both of which have been designated as UNESCO World Heritage Sites since 1983. Other tourist attractions include the Aurangabad Caves, Daulatabad Fort, Grishneshwar Temple, Jama Mosque, Bibi Ka Maqbara, Himayat Bagh, Panchakki and Salim Ali Lake. Historically, there were 52 Gates in Aurangabad, some of them extant, because of which Aurangabad is nicknamed as the "City of Gates". In 2019, the Aurangabad Industrial City (AURIC) became the first greenfield industrial smart city of India under the country's flagship Smart Cities Mission.Paithan, the imperial capital of the Satavahana dynasty (1st century BCE–2nd century CE), as well as Daulatabad or Dēvagirī, the capital of the Yadava dynasty (9th century CE–14th century CE), are located within the limits of modern Aurangabad. In 1308, the region was annexed by the Delhi Sultanate during the rule of Sultan Alauddin Khalji. In 1327, the capital of the Delhi Sultanate was shifted from Delhi to Daulatabad (in present-day Aurangabad) during the rule of Sultan Muhammad bin Tughluq, who ordered a mass migration of Delhi's population to Daulatabad. However, Muhammad bin Tughluq reversed his decision in 1334 and the capital was shifted back to Delhi. In 1499, Daulatabad became a part of the Ahmadnagar Sultanate. In 1610, a new city named Khaḍkī was established at the location of modern Aurangabad to serve as the capital of the Ahmadnagar Sultanate by the Ethiopian military leader Malik Ambar, who was brought to India as a slave but rose to become a popular Prime Minister of the Ahmadnagar Sultanate. Malik Ambar was succeeded by his son Fateh Khan, who changed the name of the city to Fatehnagar. In 1636, Aurangzeb, who was then the Mughal viceroy of the Deccan region, annexed the city into the Mughal Empire. In 1653, Aurangzeb renamed the city as "Aurangabad" and made it the capital of the Deccan region of the Mughal Empire. In 1724, the Mughal governor of the Deccan, Nizam Asaf Jah I, seceded from the Mughal Empire and founded his own Asaf Jahi dynasty. The dynasty established the State of Hyderabad with their capital initially at Aurangabad, until they transferred their capital to the city of Hyderabad in 1763. Hyderabad State became a princely state during the British Raj, and remained so for 150 years (1798–1948). Until 1956, Aurangabad remained part of Hyderabad State. In 1960, Aurangabad and the larger Marathi-speaking Marathwada region became a part of the state of Maharashtra.
