New Delhi is the capital of India, and it's also the travel hub of northern India. As well as being an excellent base for visiting wonders like the Taj Mahal, New Delhi is the commercial and cultural heart of India. With its unique attractions, exquisite culture.
The name Delhi is of uncertain etymology. One suggestion is that the name Delhi is derived from the Mauryan king, Maharaja Dhillu. However, some historians believe that the word Dilli, another name for Delhi, orignated from the Persian word Dahleez meaning frontier or threshold. Another school suggests that the city's original name is Dhillika. The Persianized surname Dahelvi is also related to residents of Delhi.

History
Delhi is believed to be the site Indraprastha, capital of the Pandavas in the Indian epic Mahabharata, founded around 5000 BC. Hindu texts state that the city of Delhi used to be referred to in Sanskrit as Hastinapur, which means "elephant-city". Archaeological evidence suggests that Indraprastha once stood where the Old Fort is today. The earliest architectural relics date back to the Maurya Period (c. 300 BC); since then, the site has seen continuous settlement. The famous Iron pillar near the Qutub Minar was commissioned by the emperor Kumara Gupta I of the Gupta dynasty (320-540) and transplanted to Delhi during the 10th century. Eight major cities have been situated in the Delhi area. The first four cities were in the southern part of present-day Delhi.
