Delhi

There are a number of myths and legends associated with the origin of the name Delhi. One of them is derived from Dhillu or Dilu, a king who built a city at this location in 50 BCE and named it after himself. Another legend holds that the name of the city is based on the 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. According to Panjab Notes and Queries, the name of the city at the time of King Prithviraj Chauhan was dilpat, and that dilpat and dilli are probably derived from the Old Hindi word dil meaning "eminence". The former director of the Archaeological Survey of India, Alexander Cunningham, mentioned that dilli later became dihli/dehli. Some suggest the coins in circulation in the region under the Tomaras were called dihliwal/dehliwal. …

Traditionally seven cities have been associated with the region of Delhi. The earliest, Indraprastha, is part of a literary description in the Sanskrit epic Mahabharata (composed c. 400 BCE to 300 CE but describing an earlier time) which situates a city on a knoll on the banks of the river Yamuna. According to art historian Catherine B. Asher, the topographical description of the Mahabharata matches the area of Purana Qila, a 14th-century CE fort of the Delhi sultanate, but the analogy does not go much further. Whereas the Mahabharata speaks of a beautifully decorated city with surrounding fortifications, the excavations have yielded "uneven findings of painted grey pottery characteristic of the eleventh century BCE; no signs of a built environment, much less fortifications, have been revealed." The earliest architectural relics date back to the Maurya period (c. …

Delhi is located in North India at 28.61°N 77.23°E / 28.61; 77.23. The city is bordered on its northern, western, and southern sides by the state of Haryana and to the east by that of Uttar Pradesh (UP). Two prominent features of the geography of Delhi are the Yamuna flood plains and the Delhi Ridge. The Yamuna River was the historical boundary between Haryana and UP, and its floodplains provide fertile alluvial soil suitable for agriculture but are prone to recurrent flooding. The Yamuna, a sacred river in Hinduism, is the only major river flowing through Delhi. The Hindon River separates Ghaziabad from the eastern part of Delhi. The Delhi Ridge originates in the Aravalli Range to the south and encircles the west, northeast, and northwest parts of the city. It reaches a height of 318 m (1,043 ft) and is a dominant feature of the region. …

Delhi's culture has been influenced by its lengthy history and historic association as the capital of India. Although a strong Punjabi Influence can be seen in language, dress and cuisine brought by the large number of refugees who came following the partition in 1947 the recent migration from other parts of India has made it a melting pot. This is exemplified by many significant monuments in the city. The Archaeological Survey of India recognises 1,200 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 built in 1656 and the Red Fort. Three World Heritage Sites—the Red Fort, Qutub Minar and Humayun's Tomb—are located in Delhi. …
