In 2001, the population of Delhi increased by 285,000 as a result of migration and by 215,000 as a result of natural population growth – this made Delhi one of the fastest growing cities in the world. By 2015, Delhi is expected to be the third-largest conurbation in the world after Tokyo and Mumbai. Dwarka Sub City, Asia’s largest planned residential area, is located within the National Capital Territory of Delhi.

After 1720, the Mughal Empire’s influence declined rapidly as the Hindu Maratha Empire rose to prominence. In 1737, Maratha forces sacked Delhi following their victory against the Mughals in the First Battle of Delhi. In 1739, the Mughal Empire lost the Battle of Karnal, following which the victorious forces of Nader Shah, the Turkic ruler of the Afsharid dynasty, invaded and looted Delhi, carrying away many treasures, including the Peacock Throne. A treaty signed in 1752 made Marathas the protectors of the Mughal throne in Delhi.

Although technically a federally administered 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.

The Delhi-Gurgaon Expressway connects Delhi with Gurgaon and the international airport. The DND Flyway and Noida-Greater Noida Expressway connect Delhi with the suburbs of Noida and Greater Noida. Delhi’s rapid rate of economic development and population growth has resulted in an increasing demand for transport, creating excessive pressure on the city’s transport infrastructure.

Summers are long and the weather is extremely hot from early April to mid-October, with the monsoon season in between. In early March, the wind direction changes from north-westerly to south-westerly. From March to May the weather is hot. The monsoon arrives at the end of June, along with an increase in humidity. The brief, mild winter starts in late November, peaks in January and heavy fog often occurs.

Delhi has been continuously inhabited since the 6th century BC. Through most of its history, Delhi has served as a capital of various kingdoms and empires. It has been captured, sacked and rebuilt several times, particularly during the medieval period, and the modern Delhi is a cluster of a number of cities spread across the metropolitan region. Delhi is believed to have been the site of Indraprastha, the legendary capital of the Pandavas during the Mahabharata. Delhi re-emerged as a major political, cultural and commercial city along the trade routes between northwest India and the Gangetic plain during the Delhi sultanates.

Delhi has hosted many major international sporting events, including the first and the ninth Asian Games, the 2010 Hockey World Cup, the 2010 Commonwealth Games and the 2011 Cricket World Cup. Delhi lost bidding for the 2014 Asian Games, and considered making a bid for the 2020 Summer Olympics. However, sports minister Manohar Singh Gill later stated that funding infrastructure would come before a 2020 bid.

Delhi is included in India’s seismic zone-IV, making it vulnerable to major earthquakes, but earthquakes have not been common in recent history.

Delhi is the largest commercial centre in northern India; it has an estimated net State Domestic Product (FY 2010) of 1578.17 billion (US$29 billion) in nominal terms and ~6300 billion (US$120 billion) in PPP terms.

Delhi’s association and geographic proximity to the capital, New Delhi, has amplified the importance of national events and holidays like Republic Day, Independence Day (15 August) and Gandhi Jayanti. On Independence Day, the Prime Minister addresses the nation from the Red Fort. Most Delhiites celebrate the day by flying kites, which are considered a symbol of freedom. The Republic Day Parade is a large cultural and military parade showcasing India’s cultural diversity and military strength. Over the centuries, Delhi has become known for its composite culture, and a festival that symbolises this is the Phool Walon Ki Sair, which takes place in September. Flowers and pankhe – fans embroidered with flowers – are offered to the shrine of 13th century Sufi saint Khwaja Bakhtiyar Kaki and the Yogmaya temple, both situated in Mehrauli.

Delhi’s culture has been influenced by its lengthy history and historic association as the capital of India. This is exemplified by many significant monuments in the city. The Archaeological Survey of India recognises 1200 heritage buildings and 175 monuments as national heritage sites. In the Old City, the Mughals and the Turkic rulers constructed several architecturally significant buildings, such as the Jama Masjid – India’s largest mosque and the Red Fort. Three World Heritage Sites – the Red Fort, Qutab Minar and Humayun’s Tomb – are located in Delhi. Other monuments include the India Gate, the Jantar Mantar – an 18th-century astronomical observatory – and the Purana Qila – a 16th century fortress. The Laxminarayan temple, Akshardham temple, the Bahá’í Lotus temple and the ISKCON temple are examples of modern architecture. Raj Ghat and associated memorials houses memorials of Mahatma Gandhi and other notable personalities. New Delhi houses several government buildings and official residences reminiscent of British colonial architecture, including the Rashtrapati Bhavan, the Secretariat, Rajpath, the Parliament of India and Vijay Chowk. Safdarjung’s Tomb is an example of the Mughal gardens style. Some regal havelis (palatial residences) are in the Old City.

Delhi’s municipal water supply is managed by the Delhi Jal Board (DJB). As of 2005–06, it supplied 650 million gallons per day (MGD), whereas the estimated consumption requirement is 963 MGD. The shortfall is met by private and public tube wells and hand pumps. At 240 MGD, the Bhakra storage is DJB’s largest water source, followed by the Yamuna and Ganges rivers. Delhi’s groundwater level is falling and its population density is increasing, so residents often encounter acute water shortage.

For the next three hundred years, Delhi was ruled by a succession of Turkic and Pashtun dynasties. They built a number of forts and townships that are part of the seven cities of Delhi. Delhi was a major centre of Sufism during this period. The Mamluk Sultanate (Delhi) was overthrown in 1290 by the Khilji dynasty (1290–1320). Under the second Khilji ruler, Ala-ud-din Khilji, the Delhi sultanate extended its control south of the Narmada River in the Deccan. The Delhi sultanate reached its greatest extent during the reign of Muhammad bin Tughluq (1325–1351). In an attempt to bring the whole of the Deccan under control, he moved his capital to Daulatabad, Maharashtra in central India, but by moving away from Delhi he lost control of the north and was forced to return to Delhi to restore order. The southern provinces then broke away. In the years following the reign of Firuz Shah Tughlaq (1351–1388), the Delhi sultanate rapidly began to lose its hold over its northern provinces. Delhi was captured and sacked by Timur Lenk in 1398. Near Delhi, Timur massacred 100,000 captives. Delhi’s decline continued under the Sayyid dynasty (1414–1451), until the sultanate was reduced to Delhi and its hinterland. Under the Afghan Lodhi dynasty (1451–1526), the Delhi sultanate recovered control of the Punjab and the Gangetic plain to once again achieve domination over northern India. However, the recovery was short-lived and in 1526 the sultanate was destroyed by Babur, founder of the Mughal dynasty.

Hinduism is Delhi’s most popular religion, with approximately 81% of Delhi’s population. The city has large communities of Muslims (11.7%), Sikhs (5%), Baha’i (0.1%), Jains (1.1%) and Christians (0.94%) in the city. Other minority religions include Buddhism, Zoroastrianism and Judaism. The principle language in Delhi is Hindustani, and Hindi (Devanagari Script) is the principal written language of the city. There is a sizable Punjabi and Urdu speaking population. Punjabi and Urdu has second language status in Delhi.

In 1526, Babur, a descendant of Genghis Khan and Timur, from the Fergana Valley in modern-day Uzbekistan, invaded India, defeated the last Lodhi sultan in the First Battle of Panipat and founded the Mughal Empire that ruled from Delhi and Agra. The Mughal dynasty ruled Delhi for more than three centuries, with a sixteen-year hiatus during the reign of Sher Shah Suri, from 1540 to 1556. In 1553, the Hindu king, Hemu Vikramaditya acceded to the throne of Delhi by defeating forces of Mughal Emperor Humayun at Agra and Delhi. However, the Mughals re-established their rule after Akbar’s army defeated Hemu during the Second Battle of Panipat in 1556. Shah Jahan built the seventh city of Delhi that bears his name Shahjahanabad, which served as the capital of the Mughal Empire from 1638 and is today known as the Old City or Old Delhi.

In 1757, the Afghan ruler, Ahmad Shah Durrani, sacked Delhi. He returned to Afghanistan leaving a Mughal puppet ruler in nominal control. The Marathas briefly occupied Delhi before their defeat in 1761 at the third battle of Panipat and the city was captured again by Ahmad Shah. However, in 1771, the Marathas established a protectorate over Delhi when the Maratha ruler, Mahadji Shinde, recaptured Delhi and the Mughal Emperor Shah Alam II was installed as a puppet ruler in 1772. In 1803, during the Second Anglo-Maratha War, the forces of British East India Company defeated the Maratha forces in the Battle of Delhi. During the Indian Rebellion of 1857, Delhi fell to the forces of East India Company after a bloody fight known as the Siege of Delhi. The city came under the direct control of the British Government in 1858. It was made a district province of the Punjab. In 1911, it was announced that the capital of British held territories in India was to be transferred from Calcutta to Delhi. The name “New Delhi” was given in 1927, and the new capital was inaugurated on 13 February 1931. New Delhi, also known as Lutyens’ Delhi, was officially declared as the capital of the Union of India after the country gained independence on 15 August 1947. During the partition of India, thousands of Hindu and Sikh refugees, mainly from West Punjab fled to Delhi, while many Muslim residents of the city migrated to Pakistan. Migration to Delhi from the rest of India continues (as of 2013), contributing more to the rise of Delhi’s population than the birth rate, which is declining.

In 2001 the total workforce in national and state governments and the quasi-government sector was 620,000, and the private sector employed 219,000. Key service industries are information technology, telecommunications, hotels, banking, media and tourism. Construction, power, health and community services, and real estate are also important to the city’s economy. Delhi has one of India’s largest and fastest growing retail industries. Manufacturing also grew considerably as consumer goods companies established manufacturing units and headquarters in the city. Delhi’s large consumer market and the availability of skilled labour has attracted foreign investment. In 2001, the manufacturing sector employed 1,440,000 workers and the city had 129,000 industrial units.

In AD 1639, the Mughal emperor Shahjahan built a new walled city in Delhi, which served as the capital of the Mughal Empire from 1649 until the Rebellion of 1857. The British captured Delhi in 1857 and the city replaced Kolkata as the seat of British government in India in 1911. A new capital city, New Delhi, was built to the south of the old city during the 1920s. When the British left India in 1947, New Delhi became the national capital and seat of government. Today Delhi contains many important historical monuments, buildings and features.

The people of Delhi are referred to as Dilliwallahs or Delhiites. The city is referenced in various idioms of the Northern Indo-Aryan languages. Examples include:

There are a number of legends associated with the origin of the name Delhi. One is that it is derived from Dhillu or Dilu, a king of Mauryan dynasty who built a city at this location in 50 BC and named it after himself. Another legend holds that the name of the city is based on the Hindi/Prakrit word dhili (loose) and that it was used by the Tomaras to refer to the city because the Iron Pillar of Delhi had a weak foundation and had to be moved. The coins in circulation in the region under the Tomaras were called dehliwal. According to the Bhavishya Purana, King Prithviraj Chauhan, of Indraprastha built a new fort in the modern-day Purana Qila area for the convenience of all four castes in his kingdom. He ordered the construction of a gateway to the fort and later named the fort dehali. Some historians believe that the name is derived from Dilli, a corruption of dehleez or dehali—both terms meaning ‘threshold’ or ‘gateway’— and symbolic of the city as a gateway to the Gangetic Plain. Another theory suggests that the city’s original name was Dhillika.
