NCT of Delhi The National Capital Territory of Delhi is a federal territory and the metropolitan region centered on New Delhi, serving as the seat of the Government of India, the Parliament of India, and the Supreme Court of India.

It hosts national institutions including the Rashtrapati Bhavan, the India Gate, the Red Fort, and cultural venues like the National Museum and the National Gallery of Modern Art.
The toponym derives from the medieval city of Delhi Sultanate capitals such as Lal Kot and Siri, later referenced in Mughal-era sources like the Ain-i-Akbari. Under British rule the area was administered within the East India Company and later the British Raj, culminating in the transfer of the capital from Calcutta to New Delhi after the Delhi Durbar of 1911. Post-independence arrangements produced constitutional instruments including the Constitution of India and the Sixty-ninth Amendment Bill debates that shaped its present status as a union territory with a legislative assembly, distinct from states like Uttar Pradesh and Haryana.
The region's history spans the ancient Mahabharata period temples and the medieval rise of the Delhi Sultanate dynasties such as the Mamluk dynasty and the Khilji dynasty, the establishment of the Mughal Empire with emperors like Humayun and Shah Jahan, and the construction of monuments like the Jama Masjid and the Qutub Minar. In the 19th century Delhi figured in the Indian Rebellion of 1857 and subsequent British urban planning by architects such as Edwin Lutyens and Herbert Baker for New Delhi.

Law enforcement is conducted by the Delhi Police while municipal functions are handled by bodies including the Municipal Corporation of Delhi and the New Delhi Municipal Council.

Ongoing jurisdictional matters have been litigated before the Supreme Court of India under constitutional provisions.

Religious sites reflect pluralism with major places such as the Akshardham Temple, the Lotus Temple, the Jama Masjid, and the Gurudwara Bangla Sahib.
