Overview
Delhi, officially the National Capital Territory of Delhi, is a union territory and megacity in northern India. It contains New Delhi, the national capital, and extends across 1,484 square kilometres along and around the Yamuna River. The territory borders Uttar Pradesh to the east and Haryana on its other sides. Delhi is both a major urban region and a constitutional unit with its own legislature, high court and elected executive, although important powers remain with the Union government. New Delhi is administered through arrangements involving both the central government and the Government of the National Capital Territory of Delhi. Delhi's importance is rooted in its position between the northwestern approaches to the Indian subcontinent and the Gangetic Plain. The area has been associated in tradition with Indraprastha, the city described in the Mahabharata, although archaeological evidence does not establish a direct connection between the literary city and a continuous ancient settlement at the site. Material remains include Mauryan-period evidence and an inscription associated with Emperor Ashoka. In the eleventh century, Tomara ruler Anang Pal established Lal Kot, which was later expanded and renamed Qila Rai Pithora under the Chauhans. From the thirteenth through the nineteenth centuries, Delhi served as the seat of the Delhi Sultanate and the Mughal Empire, with interruptions and periods of reduced political control. Successive rulers established fortified settlements and capitals, contributing to the city's traditional description as a place of multiple historical cities. Qutb-ud-din Aibak initiated the Qutb complex, while Iltutmish consolidated the early sultanate. Delhi also became an important centre of Sufi culture, Urdu literary development and qawwali music. The Mughal emperor Shah Jahan founded Shahjahanabad in the seventeenth century; its surviving core is commonly known as Old Delhi. The city experienced repeated conflict, occupation and devastation, including Timur's invasion in 1398, Nader Shah's sack in 1739 and struggles among Mughal, Maratha, Afghan and British forces. The British East India Company took control after the Battle of Delhi in 1803. Following the 1857 rebellion, Delhi came under direct British rule. In 1911 the British announced the transfer of the imperial capital from Calcutta, and New Delhi was inaugurated as the new capital in 1931. After Indian independence in 1947, New Delhi remained the capital of India. Partition transformed Delhi's population and social geography: large numbers of Hindu and Sikh refugees arrived from western Punjab, while many Muslim residents departed for Pakistan. Post-independence migration, industrialisation, government expansion and suburban growth turned Delhi into one of South Asia's largest metropolitan regions. The wider National Capital Region includes cities such as Gurugram, Noida, Ghaziabad and Faridabad and has a population exceeding that of the NCT itself. Delhi's contemporary role combines national administration with education, media, technology, finance, retail, tourism and transport. It hosts Parliament, the Supreme Court, central ministries, diplomatic missions and major cultural institutions. It has also hosted major international and sporting events, including the 1951 and 1982 Asian Games, the 2010 Commonwealth Games, the 2012 BRICS summit and the 2023 G20 summit. Its historic monuments, including the Qutb Minar, Humayun's Tomb and the Red Fort, are UNESCO World Heritage Sites. At the same time, Delhi faces air pollution, water stress, congestion, uneven infrastructure, housing pressure and recurring communal and political tensions.
History
Delhi's historical identity is layered across settlements, fortifications and capitals established over more than two millennia. Literary tradition associates the Yamuna-side region with Indraprastha, but archaeology has not demonstrated that the Purana Qila site was the fully developed city described in the Mahabharata. Evidence from the Mauryan period, including an Ashokan inscription discovered near Srinivaspuri, confirms the area's early strategic and political importance. The medieval urban history commonly begins with Lal Kot, attributed to Tomara ruler Anang Pal in the eleventh century. Chauhan rulers expanded the settlement into Qila Rai Pithora. After Muhammad Ghori's victory over Prithviraj Chauhan in 1192, Qutb-ud-din Aibak governed the conquered territories and established the political foundation of the Delhi Sultanate. The Qutb Minar and Quwwat-al-Islam mosque belong to this formative period, while Iltutmish consolidated the sultanate and made Delhi a durable centre of northern Indian power. Several Turkic, Indian and Afghan dynasties ruled from Delhi over the following centuries. The Khaljis expanded toward the Deccan, and Muhammad bin Tughluq's attempt to shift the capital to Daulatabad demonstrated both the scale of his ambitions and the logistical importance of Delhi. The city suffered repeated invasions and political contraction, most dramatically during Timur's capture and sack in 1398. The Lodi dynasty restored a degree of regional authority before Babur defeated Ibrahim Lodi at Panipat in 1526 and founded the Mughal Empire. Mughal rule made Delhi a principal imperial centre, although Agra and other cities also carried political weight. Shah Jahan established Shahjahanabad in 1638, creating the walled city now identified with Old Delhi. Mughal authority weakened after Aurangzeb's death in 1707. Maratha, Persian and Afghan interventions repeatedly reshaped the city, including Nader Shah's devastating 1739 invasion. The Marathas later became protectors of the Mughal court before British forces defeated them in 1803. Delhi's role in the 1857 uprising led to a decisive colonial transformation. After the rebellion was suppressed, the British placed the city under direct Crown control. In 1911 they announced that the capital of British India would move from Calcutta to Delhi. New Delhi, planned largely by Edwin Lutyens and Herbert Baker, was inaugurated in 1931. It became the capital of independent India in 1947 and of the Republic of India after the Constitution took effect in 1950. Partition produced one of the largest demographic and cultural changes in Delhi's modern history. Hundreds of thousands of Hindu and Sikh refugees arrived from western Punjab, while a substantial part of the Muslim population left for Pakistan. The expanding city subsequently absorbed migration from across India, generating new residential colonies, industrial areas, markets and institutions. The 1956 reorganisation made Delhi a Union Territory. The 1991 constitutional amendment created the National Capital Territory framework and restored a legislative assembly, while retaining substantial central-government authority. Modern Delhi is the administrative heart of India and the core of the National Capital Region. Its historic monuments coexist with universities, technology firms, hospitals, cultural venues, diplomatic missions, manufacturing and extensive transport networks. The city's growth has brought national influence and economic opportunity, but also pollution, water scarcity, traffic, informal housing, environmental degradation and episodes of political and communal conflict. Delhi's present identity therefore combines imperial and postcolonial heritage with the pressures of a rapidly expanding capital-region metropolis.
