It is the capital city of India.

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.

The city is believed to be the site of Indraprastha, the legendary capital of the Pandavas in the Indian epic Mahabharata.

Delhi’s urban area is now considered to extend beyond the NCT boundaries and include the neighbouring satellite cities of Faridabad, Gurgaon, Sonipat, Ghaziabad and Noida in an area now called Central National Capital Region (CNCR) and had an estimated 2016 population of over 26 million people, making it the world’s second-largest urban area according to United Nations.

Recent estimates of the metro economy of its urban area have ranked Delhi either the most or second-most productive metro area of India.
