Uttar Pradesh (; Hindi: [ˈʊtːəɾ pɾəˈdeːʃ] (listen), lit. 'Northern Province') is a state in northern India. With over 200 million inhabitants, it is the most populated state in India as well as the most populous country subdivision in the world. It was established in 1950 after India had become a republic. It was a successor to the United Provinces (UP) during the period of the Dominion of India (1947–1950), which in turn was a successor to the United Provinces (UP) established in 1935, and eventually of the United Provinces of Agra and Oudh established in 1902 during the British Raj. The state is divided into 18 divisions and 75 districts, with the state capital being Lucknow, and Prayagraj serving as the judicial capital. On 9 November 2000, a new state, Uttaranchal (now Uttarakhand), was created from Uttar Pradesh's western Himalayan hill region. The two major rivers of the state, the Ganges and its tributary Yamuna, meet at the Triveni Sangam in Prayagraj, a Hindu pilgrimage site. Other notable rivers are Gomti and Saryu. The forest cover in the state is 6.1 per cent of the state's geographical area. The cultivable area is 82 per cent of total geographical area and net area sown is 68.5 per cent of cultivable area.The state is bordered by Rajasthan to the west, Haryana, Himachal Pradesh and Delhi to the northwest, Uttarakhand and an international border with Nepal to the north, Bihar to the east, Madhya Pradesh to the south, and touches the states of Jharkhand and Chhattisgarh to the southeast. It covers 240,928 km2 (93,023 sq mi), equal to 7.3% of the total area of India, and is the fourth-largest Indian state by area. Though long known for sugar production, the state's economy is now dominated by the services industry. The service sector comprises travel and tourism, hotel industry, real estate, insurance and financial consultancies. The economy of Uttar Pradesh is the third-largest state economy in India with ₹17.05 lakh crore (US$210 billion) in gross domestic product and a per capita GSDP of ₹65,431 (US$820). President's rule has been imposed in Uttar Pradesh ten times since 1968, for different reasons and for a total of 1,700 days. The state has currently three international airports, Chaudhary Charan Singh International Airport (Lucknow), Lal Bahadur Shastri Airport (Varanasi) and Kushinagar International Airport (Kushinagar).

Uttar Pradesh was home to most of the mainstream political entities that have existed in ancient and medieval India including the Maurya Empire, Harsha Empire, Gupta Empire, Pala Empire, Delhi Sultanate, Mughal Empire as well as many other empires. At the time of Indian independence movement in the early 20th century, there were three major princely states in Uttar Pradesh – Ramgadi, Rampur and Benares. The state houses several holy Hindu temples and pilgrimage centres. Uttar Pradesh has three World Heritage sites and ranks first among tourist destinations in India. Uttar Pradesh has several historical, natural, and religious tourist destinations, including Agra, Aligarh, Ayodhya, Kushinagar, Prayagraj, Varanasi and Vrindavan.

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.
