Delhi, India's sprawling capital territory, is a city where ancient monuments stand beside ultramodern malls and Mughal gardens shadow gleaming corporate towers. As one of the world's most populous cities, Delhi offers an intoxicating blend of history spanning 3,000 years, from Iron Age settlements to British colonial architecture. The city serves as the political, cultural, and commercial heart of India, drawing millions of visitors annually to its UNESCO World Heritage Sites, vibrant street food scene, and legendary bazaars.
Delhi's recorded history spans over three millennia, from the legendary city of Indraprastha mentioned in the Mahabharata to its role as the capital of modern India. The city holds the unique distinction of having been built, destroyed, and rebuilt at least seven times by successive dynasties — Rajputs, Delhi Sultanate sultans, Mughals, and finally the British — each leaving layers of monuments that make Delhi one of the world's great open-air museums of history. The Mughal era gave Delhi its most iconic landmarks, including the Red Fort and Jama Masjid, while the British built Lutyens' New Delhi as an imperial capital in 1931, just sixteen years before Indian independence. Today Delhi is a living palimpsest where medieval ruins, Mughal gardens, and colonial boulevards coexist with a twenty-first century metropolis of 33 million people.
Historical timeline
Key moments that shaped Delhi.
-
1
Indraprastha — mythological capital of the Pandavas described in the Mahabharata — believed to have occupied the site of present-day Purana Qila on the Yamuna's western bank.
-
2
The Delhi region is part of the Mauryan Empire. An Ashokan rock edict (c. 250 BCE) survives at Srinivaspuri, one of only two in Delhi. The area later passes through Gupta and Rajput hands.
-
3
Anangpal II of the Tomar Rajput dynasty founds Lal Kot (the 'Red Citadel') near Mehrauli — the first of Delhi's historic cities. The Iron Pillar, dating to the Gupta period, is installed here.
-
4
Prithviraj Chauhan of the Chahamana dynasty expands Lal Kot into Qila Rai Pithora, the second Delhi. He is defeated by Muhammad of Ghor at the Second Battle of Tarain (1192), ending Rajput rule.
-
5
Qutb-ud-din Aibak, viceroy of Muhammad of Ghor, begins construction of the Quwwat-ul-Islam Mosque and the Qutub Minar — Delhi's oldest surviving monuments and the subcontinent's first mosque.
-
6
The Slave (Mamluk) Dynasty rules from Delhi. Iltutmish (r. 1211–1236) completes the Qutub Minar and transforms Delhi into a major Islamic capital. Razia Sultana (r. 1236–1240) becomes the first female ruler of an Islamic state in the subcontinent.
-
7
Alauddin Khilji builds Siri Fort — the second city of Delhi — to defend against Mongol invasions. He also constructs the vast Alai Minar (intended to be twice the height of the Qutub Minar, unfinished) and the Hauz Khas reservoir complex.
-
8
The Tughlaq dynasty builds three new Delhis: Tughlaqabad (1321, Ghiyasuddin Tughlaq), Jahanpanah (1326, Muhammad bin Tughlaq), and Firozabad/Feroz Shah Kotla (1354, Firoz Shah Tughlaq). Delhi reaches its medieval peak as one of the world's largest cities with a population estimated at 400,000.
-
9
Timur (Tamerlane) sacks Delhi, massacring hundreds of thousands of inhabitants. The city is devastated and takes decades to recover. The weakened Delhi Sultanate never fully regains its former power.
-
10
Babur defeats Ibrahim Lodi at the First Battle of Panipat (96km north of Delhi), establishing the Mughal Empire. Delhi becomes the empire's administrative centre, though Agra is the primary capital under early Mughals.
-
11
Humayun begins construction of Dinpanah (sixth Delhi) at Purana Qila. Sher Shah Suri defeats Humayun (1540), renames the city Shergarh, and builds the Qila-i-Kuhna Mosque within the fort. Humayun recaptures Delhi in 1555.
-
12
Humayun's Tomb completed by his widow Hamida Banu Begum — the first great Mughal garden tomb in India and the acknowledged template for the Taj Mahal. UNESCO World Heritage Site.
-
13
Emperor Shah Jahan builds Shahjahanabad — the seventh and last of Delhi's historic cities — on the Yamuna bank. The Red Fort (Lal Qila, completed 1648) and Jama Masjid (completed 1656) are the centrepieces. Chandni Chowk is laid out as a grand bazaar. Shahjahanabad remains the political heart of Mughal India for two centuries.
-
14
Persian ruler Nadir Shah invades and sacks Delhi, massacring 20,000–30,000 citizens in a single day (the Qatl-e-Aam) and looting the Peacock Throne and Koh-i-Noor diamond. The Mughal Empire never recovers its former power.
-
15
The British East India Company defeats the Marathas at the Battle of Delhi and takes control of the city. The Mughal emperor Bahadur Shah II becomes a pensioner under British protection in the Red Fort.
-
16
The Indian Rebellion (First War of Independence) begins in May. Delhi becomes a major centre of the uprising. British forces besiege and retake Delhi in September. The last Mughal emperor Bahadur Shah Zafar is exiled to Rangoon, ending 300 years of Mughal rule.
-
17
At the Delhi Durbar, King George V announces the transfer of the British Indian capital from Calcutta to Delhi. Construction of New Delhi — designed by Edwin Lutyens and Herbert Baker — begins. Coronation Park marks the durbar site.
-
18
New Delhi is officially inaugurated. Rashtrapati Bhavan (Viceroy's House), the Secretariat buildings, and Rajpath (now Kartavya Path) form the ceremonial core of the imperial capital.
-
19
India gains independence on 15 August 1947. Prime Minister Jawaharlal Nehru raises the flag at the Red Fort. Partition of British India triggers one of history's largest mass migrations — an estimated 500,000 refugees flood into Delhi from Pakistan, transforming the city's demographics permanently.
-
20
Delhi is designated a Union Territory (and later a National Capital Territory with its own legislature). The city grows from under 2 million in 1947 to over 33 million today, becoming one of the world's largest urban agglomerations and a global hub of politics, culture, and commerce.
Historical eras
The chapters of Delhi's past.
Ancient & Early Medieval
From the legendary Mahabharata era through Mauryan and Gupta rule. The Ashokan rock edict at Srinivaspuri (c. 250 BCE) is Delhi's oldest surviving historical inscription. The 4th–5th century CE Iron Pillar at the Qutb Complex is a marvel of early Indian metallurgy.
Rajput Delhi
The Tomar and Chahamana Rajput dynasties establish the first cities of Delhi — Lal Kot and Qila Rai Pithora at Mehrauli. The Rajput era ends with the defeat of Prithviraj Chauhan at the Second Battle of Tarain (1192), opening north India to the Delhi Sultanate.
Delhi Sultanate
Five successive dynasties — Slave, Khilji, Tughlaq, Sayyid, and Lodi — rule from Delhi, transforming it into the subcontinent's great Islamic capital. The Sultanate builds five distinct walled cities (Siri, Tughlaqabad, Jahanpanah, Firozabad, and expands Lal Kot). At its peak in the early 14th century, Delhi is one of the world's largest and wealthiest cities.
Mughal Empire
The Mughal period produces Delhi's most iconic monuments. Humayun's Tomb (1565) establishes the Mughal garden-tomb tradition; Shah Jahan's Shahjahanabad (1638) — with the Red Fort and Jama Masjid — becomes the empire's glittering capital. By the 18th century repeated invasions (Nadir Shah 1739, Ahmad Shah Durrani 1757) weaken the empire, and the last Mughal emperor is exiled after the 1857 Rebellion.
British Raj
The British East India Company takes Delhi in 1803. After the 1857 Rebellion the British Crown assumes direct rule. In 1911 the capital transfers from Calcutta to Delhi; architect Edwin Lutyens designs New Delhi — inaugurated in 1931 — as an imperial capital of wide boulevards, bungalows, and monumental civic buildings.
Republic of India
Independence on 15 August 1947 and the traumatic partition reshape Delhi demographically and politically. The city absorbs hundreds of thousands of refugees and rapidly expands southward and westward. Delhi is designated a National Capital Territory in 1956 with special administrative status. The city grows into one of the world's megacities and remains India's political and cultural capital.
Historical sites
Places where Delhi's past comes alive.
Qutub Minar
A 73-metre-tall minaret of red sandstone and marble, begun by Qutb-ud-din Aibak in 1193 and completed by Iltutmish. The world's tallest brick minaret and the centrepiece of the Qutb Complex, which also contains the Quwwat-ul-Islam Mosque, the Iron Pillar (4th–5th century CE), and the Alai Darwaza. UNESCO World Heritage Site.
Where: New Delhi 110030
Red Fort (Lal Qila)
The magnificent Mughal palace-fort built by Shah Jahan as the seat of Mughal power, enclosed by 2km of red sandstone walls rising up to 33 metres. Within the fort: Diwan-i-Aam (Hall of Public Audience), Diwan-i-Khas (Hall of Private Audience, once housing the Peacock Throne), royal baths (Hammam), and the Moti Masjid (Pearl Mosque). The prime minister addresses the nation from its ramparts on Independence Day (15 Aug). UNESCO World Heritage Site.
Where: New Delhi 110006
Humayun's Tomb
The magnificent tomb of Mughal Emperor Humayun, built by his widow in 1565–72. Considered the first great example of Mughal architecture on the Indian subcontinent and the acknowledged precursor to the Taj Mahal, featuring a double-dome, Persian charbagh garden, and red sandstone and white marble inlay. Over 100 Mughal family members are also buried in the complex. UNESCO World Heritage Site.
Where: New Delhi 110013
Purana Qila (Old Fort)
The sixth city of Delhi, begun by Humayun as Dinpanah and completed by Sher Shah Suri. The fort walls enclose the elegant Qila-i-Kuhna Mosque (1541) and the Sher Mandal octagonal tower (used as Humayun's library). Archaeological excavations have confirmed occupation from 1000 BCE, lending credibility to the Indraprastha legend. A pleasant boating lake sits outside the northern gate.
Where: New Delhi 110003
Mehrauli Archaeological Park
A remarkable 200-acre urban archaeological zone adjacent to the Qutub Minar complex, containing over 440 historically significant monuments spanning 1,000 years — from Tomar Rajput structures to Mughal tombs, mosques, and British-era buildings. Highlights include the tomb of Adham Khan (1561), Jamali-Kamali Mosque and Tomb, Balban's Tomb (one of Delhi's earliest true arches), and Rajon ki Baoli stepwell.
Where: New Delhi 110030
Tughlaqabad Fort
The third city of Delhi, founded by Ghiyasuddin Tughlaq in 1321. The immense 6.5km-long fortified city — now largely ruined — contains the remains of palaces, a citadel, and an artificial lake. Ghiyasuddin's distinctive sloping-wall tomb stands across the road. The fort was famously cursed by the Sufi saint Nizamuddin Auliya and abandoned within years of completion.
Where: New Delhi 110044
Feroz Shah Kotla
The fifth Delhi, built by Firoz Shah Tughlaq in 1354, now largely ruined. The site contains a 3rd-century BCE Ashokan pillar (moved here by Firoz Shah), a pyramidal structure housing the pillar, a mosque, and a baoli (stepwell). Famously known today as a place where locals leave milk and incense for djinn (spirits) believed to inhabit the ruins.
Where: New Delhi 110002
Safdarjung's Tomb
The last great garden tomb built in the Mughal tradition, constructed for Nawab Safdarjung, prime minister of the Mughal emperor Ahmad Shah. Though considered a late and somewhat decadent example of Mughal architecture, the sandstone and marble tomb set in a formal charbagh (four-quadrant) garden is far less crowded than Humayun's Tomb and offers a tranquil experience.
Where: New Delhi 110029
Lodi Garden
A 90-acre landscaped garden containing the tombs of Sayyid and Lodi rulers of the Delhi Sultanate, including the Muhammad Shah's Tomb (1444) and Sikandar Lodi's Tomb (1517). One of the most beautiful green spaces in Delhi, the garden is also a birdwatching hotspot (150+ species) and a favourite morning walk destination for Delhi residents.
Where: New Delhi 110003
Jama Masjid
India's largest mosque, built by Shah Jahan and completed in 1656. The mosque can accommodate over 25,000 worshippers and features two 40-metre minarets and three marble domes. The main courtyard is paved with black-and-white marble. Climbing the southern minaret rewards visitors with panoramic views of Old Delhi's skyline.
Where: New Delhi 110006
Coronation Park
The site of all three Delhi Durbars — grand imperial assemblies held in 1877, 1903, and 1911. Here in 1911 King George V announced the transfer of the capital from Calcutta to Delhi. The park contains a granite obelisk marking the spot and a collection of displaced Raj-era statues (including a headless George V), moved here after independence.
Where: North Delhi
