Madhya Pradesh (, Hindi: [ˈməd̪ʱjə pɾəˈdeːʃ] (listen); meaning 'central province') is a state in central India. Its capital is Bhopal, and the largest city is Indore, with Jabalpur, Ujjain, Gwalior, Satna, and Guna being the other major cities. Madhya Pradesh is the second largest Indian state by area and the fifth largest state by population with over 72 million residents. It borders the states of Uttar Pradesh to the northeast, Chhattisgarh to the east, Maharashtra to the south, Gujarat to the west, and Rajasthan to the northwest.The area covered by the present-day Madhya Pradesh includes the area of the ancient Avanti Mahajanapada, whose capital Ujjain (also known as Avantika) arose as a major city during the second wave of Indian urbanisation in the sixth century BCE. Subsequently, the region was ruled by the major dynasties of India. The Maratha Empire dominated the majority of the 18th century. After the Anglo-Maratha Wars in the 19th century, the region was divided into several princely states under the British and incorporated into Central Provinces and Berar and the Central India Agency. After India's independence, Madhya Pradesh state was created with Nagpur as its capital: this state included the southern parts of the present-day Madhya Pradesh and northeastern portion of today's Maharashtra. In 1956, this state was reorganised and its parts were combined with the states of Madhya Bharat, Vindhya Pradesh and Bhopal to form the new Madhya Pradesh state, the Marathi-speaking Vidarbha region was removed and merged with the Bombay State. This state was the largest in India by area until 2000, when its southeastern Chhattisgarh region was designated a separate state. The economy of Madhya Pradesh is the 10th-largest in India, with a gross state domestic product (GSDP) of ₹9.17 trillion (US$110 billion) and has the country's 26th highest per-capita income of ₹ 109372. Madhya Pradesh ranks 23rd among Indian states in human development index. Rich in mineral resources, Madhya Pradesh has the largest reserves of diamond and copper in India. 25.14% of its area is under forest cover. Its tourism industry has seen considerable growth, with the state topping the National Tourism Awards in 2010–11. In recent years, the state's GDP growth has been above the national average. In 2019–20, state's GSDP was recorded at 9.07.

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.
