Delhi

Delhi (/ˈdɛli/, Hindustani pronunciation: [d̪ɪlliː] Dilli), officially the National Capital Territory of Delhi, is the capital territory of India. Delhi is historically and culturally connected to both the Upper Doab of the Yamuna-Ganges river system and the Punjab region. It is bordered by Haryana on three sides and by Uttar Pradesh to the east. It is the largest city in India in terms of geographical area - about 1,484 square kilometres (573 sq mi). It has a population of about 16.3 million, making it the second most populous city and second most populous urban agglomeration in India and 3^rd largest urban area in the world. Such is the nature of urban expansion in Delhi that its growth has expanded beyond the NCT to incorporate towns in neighbouring states and at its largest extent can count a population of about 25 million residents as of 2014.

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, ransacked and rebuilt several times, particularly during the medieval period, and modern Delhi is a cluster of a number of cities spread across the metropolitan region.

New Delhi

New Delhi (ⁱ/ˌnjuː ˈdɛli/) is a municipality and district in Delhi which serves as the capital and seat of government of India. In addition, it also serves as the seat of Government of Delhi.

The foundation stone of the city was laid by George V, Emperor of India during the Delhi Durbar of 1911. It was designed by British architects, Sir Edwin Lutyens and Sir Herbert Baker. The new capital was inaugurated on 13 February 1931, by India's Viceroy Lord Irwin.

Although colloquially Delhi and New Delhi as names are used interchangeably to refer to the jurisdiction of NCT of Delhi, these are two distinct entities, and the latter is a small part of the former.

New Delhi has been selected as one of the hundred Indian cities to be developed as a smart city under PM Narendra Modi's flagship Smart Cities Mission.

Establishment

Calcutta (now Kolkata) was the capital of India during the British Raj until December 1911. However, Delhi had served as the political and financial centre of several empires of ancient India and the Delhi Sultanate, most notably of the Mughal Empire from 1649 to 1857. During the early 1900s, a proposal was made to the British administration to shift the capital of the British Indian Empire (as it was officially called) from Calcutta to Delhi. Unlike Calcutta, which was located on the eastern coast of India, Delhi was at the center of northern India and the Government of British India felt that it would be logistically easier to administer India from the latter rather than the former.

India

India, officially the Republic of India (Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country with over 1.2 billion people, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the south-west, and the Bay of Bengal on the south-east, it shares land borders with Pakistan to the west;China, Nepal, and Bhutan to the north-east; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; in addition, India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

Home to the ancient Indus Valley Civilisation and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history. Four religions—Hinduism, Buddhism, Jainism, and Sikhism—originated here, whereas Zoroastrianism, Judaism, Christianity, and Islam arrived in the 1st millennium CE and also shaped the region's diverse culture. Gradually annexed by and brought under the administration of the British East India Company from the early 18th century and administered directly by the United Kingdom after the Indian Rebellion of 1857, India became an independent nation in 1947 after a struggle for independence that was marked by non-violent resistance led by Mahatma Gandhi.

Old Delhi

Old Delhi is a walled city of Delhi, India, was founded as Shahjahanabad (Persian: شاه جهان آباد‎‎) by Mughal Emperor Shahjahan in 1639. It remained the capital of the Mughals until the end of the Mughal dynasty. It was once filled with mansions of nobles and members of the royal court, along with elegant mosques and gardens. Today, despite having become extremely crowded and dilapidated, it still serves as the symbolic heart of metropolitan Delhi.

History

The site of Shahjahanabad is north of earlier settlements of Delhi. Its southern part overlaps some of the area that was settled by the Tughlaqs in the 14th century when it was the seat of Delhi Sultanate. The sultanates ruled from Delhi between 1206 and 1526, when the last was replaced by the Mughal dynasty. The five dynasties were the Mamluk dynasty (1206–90), the Khilji dynasty (1290–1320), the Tughlaq dynasty (1320–1414), the Sayyid dynasty (1414–51), and the Lodi dynasty (1451–1526).

Delhi remained an important place for the Mughals, who built palaces and forts . Most importantly, it was Shah Jahan, who had the walled city built from 1638 to 1649, containing the Lal Qila and the Chandni Chowk. Daryaganj had the original cantonment of Delhi, after 1803, where a native regiment of Delhi garrison was stationed, which was later shifted to Ridge area. East of Daryaganj was Raj ghat Gate of the walled city, opening at Raj Ghat on Yamuna River. First wholesale market of Old Delhi opened as the hardware market in Chawri Bazaar in 1840, the next wholesale market was that of dry fruits, spices and herbs at Khari Baoli, opening in 1850. The Phool Mandi (Flower Market) of Daryaganj was established in 1869, and even today, despite serving a small geographical area, it is of great importance due to dense population.

Jantar Mantar

The Jantar Mantar is an equinoctial sundial, consisting a gigantic triangular gnomon with the hypotenuse parallel to the Earth's axis. On either side of the gnomon is a quadrant of a circle, parallel to the plane of the equator. The instrument is intended to measure the time of day, correct to half a second and declination of the Sun and the other heavenly bodies.

There are five Jantar Mantar monuments in India, of which the largest is in Jaipur which features many instruments along with the world's largest stone sundial. The Vrihat Samrat yantra is a sundial that can give the local time to an accuracy of 2 seconds.

History

In the early 18th century, Maharaja Jai Singh II of Jaipur constructed five Jantar Mantars in total, in New Delhi, Jaipur, Ujjain, Mathura and Varanasi; they were completed between 1724 and 1735.

The jantars have evocative names like Samrat Yantra, Jai Prakash, Ram Yantra and Niyati Chakra; each of which are used to for various astronomical calculations. The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets.
