Delhi

Delhi, officially known as the National Capital Territory of Delhi (NCT), is a Union Territory and the capital region of India. It serves as the political, cultural, and economic centre of the country and is one of the most historically significant cities in South Asia. The territory includes New Delhi, which functions as the seat of the Government of India, housing the nation’s key administrative and legislative institutions.

Geographical Overview

Delhi is situated in northern India, bordered by the state of Haryana on three sides and Uttar Pradesh to the east, along the banks of the River Yamuna. Covering an area of about 1,484 square kilometres, it stands at an elevation ranging from 213 to 305 metres above sea level. The region experiences an extreme climate, with hot summers, a humid monsoon season, and cold winters.
The Yamuna River, though considerably reduced in flow, remains Delhi’s primary natural water source. The terrain includes the Delhi Ridge, an extension of the Aravalli Range, which contributes to the city’s topographical diversity and ecological importance.

Historical Background

Delhi’s history spans several millennia, with archaeological evidence suggesting continuous habitation since the 6th century BCE. The city has been the seat of power for numerous dynasties and empires, making it a crucial centre in India’s political evolution.

• The Mauryas and Guptas ruled ancient Delhi, followed by Tomar and Chauhan Rajputs, who established the early city of Lal Kot.
• In the 12th century, Qutb-ud-din Aibak founded the Delhi Sultanate, marking the beginning of Islamic rule. The construction of the Qutub Minar and Quwwat-ul-Islam Mosque began during this era.
• The Mughal Empire, under Emperor Shah Jahan, built Shahjahanabad (Old Delhi) in the 17th century, centred around the Red Fort and Jama Masjid.
• The British made Delhi their capital in 1911, shifting from Calcutta, and later commissioned New Delhi, designed by Sir Edwin Lutyens and Sir Herbert Baker, inaugurated in 1931.
• After India’s independence in 1947, Delhi became the capital of the Republic of India, symbolising national unity and modern governance.

Administrative and Political Structure

The National Capital Territory of Delhi was granted special status under the 69th Constitutional Amendment Act, 1991, which provided for an elected Legislative Assembly and a Council of Ministers. The Lieutenant Governor acts as the representative of the President of India, while the Chief Minister heads the local government.
Delhi is divided into eleven districts, including New Delhi, South Delhi, North Delhi, East Delhi, West Delhi, and others. The New Delhi Municipal Council (NDMC) administers the core capital area, while the Municipal Corporation of Delhi (MCD) governs most of the metropolis. The Delhi Police, under the Ministry of Home Affairs, manages law and order.

Demography and Society

As per the 2011 Census, Delhi’s population was around 16.8 million, with projections suggesting over 20 million residents today, making it one of the most populous cities globally. The city’s population is highly diverse, comprising communities from across India. The official languages are Hindi and English, while Punjabi and Urdu hold additional recognition.
The population reflects multiple faiths — predominantly Hindu, with significant Muslim, Sikh, Christian, and Jain minorities. Delhi’s cosmopolitan nature has fostered a dynamic social culture blending traditional and modern lifestyles. Literacy exceeds 86%, supported by numerous educational and professional institutions.

Economy and Infrastructure

Delhi boasts one of India’s most robust urban economies, contributing significantly to the nation’s GDP. The economy is dominated by services, trade, real estate, tourism, and information technology.

• Connaught Place, Karol Bagh, and Nehru Place are major commercial zones.
• The Delhi NCR (National Capital Region), including Gurgaon, Noida, and Faridabad, has evolved into a global business and technology hub.
• The city also hosts major industrial areas such as Okhla, Bawana, and Narela, focusing on light manufacturing and export-oriented industries.

Delhi is a major centre for banking, telecommunications, healthcare, and education. The Delhi Metro, inaugurated in 2002, has revolutionised urban transport, connecting vast areas efficiently and sustainably. The Indira Gandhi International Airport is among the busiest in South Asia, handling both domestic and international traffic.

Cultural Heritage

Delhi’s cultural landscape is an amalgamation of ancient traditions and contemporary expressions. It is home to three UNESCO World Heritage Sites — the Red Fort, Humayun’s Tomb, and the Qutub Minar Complex.

Urban Development and Environment

Delhi is part of the National Capital Region (NCR), a metropolitan cluster including Noida, Gurugram, Ghaziabad, and Faridabad. Urban expansion has led to both development and environmental challenges.
Air pollution remains a critical issue, with particulate matter levels often exceeding international safety standards. The Odd-Even traffic scheme, expansion of CNG-based transport, and tree plantation drives are among the measures to combat pollution. The city’s Yamuna River Restoration Project aims to revive the river’s ecosystem.
Green spaces such as the Lodhi Gardens, Deer Park, and Ridge Forest play a vital role in maintaining ecological balance.

Transport and Connectivity

Delhi has a well-integrated transport system:

• Delhi Metro, covering over 390 kilometres, forms the backbone of public transport.
• DTC (Delhi Transport Corporation) operates extensive bus networks.
• Major highways such as NH 44, NH 48, and NH 9 connect Delhi to surrounding states.
• Indira Gandhi International Airport serves as India’s largest aviation hub.

Intra-city transport is supported by auto-rickshaws, taxis, and app-based mobility services. The city is also enhancing infrastructure for electric vehicles and cycling tracks to promote sustainable mobility.

Tourism and Landmarks

Delhi’s historic and architectural landmarks attract millions of visitors annually. Key attractions include:

• Red Fort, India Gate, and Rashtrapati Bhavan
