New Delhi is the capital of India and an administrative district of the National Capital Territory of Delhi. New Delhi is the seat of all three branches of the government of India, hosting the Rashtrapati Bhavan, Parliament House, and the Supreme Court of India.
Although colloquially Delhi and New Delhi are used interchangeably to refer to the National Capital Territory of Delhi, these are two distinct entities, with New Delhi forming a small part of the city of Delhi. The National Capital Region is a much larger entity comprising the entire NCT along with adjoining districts in neighbouring states, including Ghaziabad, Noida, Gurgaon and Faridabad.
The foundation stone of New Delhi was laid by George V during the Delhi Durbar of 1911. It was designed by British architects Edwin Lutyens and Herbert Baker. The new capital was inaugurated on 13 February 1931, by Viceroy and Governor-General Irwin.
