Prerequisites

The Hook: Two Buildings, One Decade

Connect

In 1311 Alauddin Khalji’s builders finished the Alai Darwaza, a red-sandstone gateway in Delhi with India’s oldest surviving true dome. In 1349, under the Phani Nagavanshi king Ramchandra Dev, the Madwa Mahal went up near Bhoramdeo in Kabirdham district: a Shiva temple in the older Indian temple tradition, with carved figures on its walls.

Two buildings, less than forty years apart, built on completely different principles. What were the new principles that the Sultans brought to Delhi, and how did they change Indian architecture?

Why it matters: Prelims loves “first” questions (first true arch, first true dome, first tomb, first double dome) and builder–monument matching. Mains asks about the features of Indo-Islamic architecture and its synthesis with Indian traditions.


What Was New: Features of Indo-Islamic Architecture

FeatureDetail
True arch (मेहराब)Built from wedge-shaped stones (voussoirs) locked by a central keystone, so the load is carried sideways. Indian builders had used the corbelled (false) arch, made by stepping stones inwards
True dome (गुंबद)A dome of voussoirs raised over a square room using squinches or pendentives to turn the square into a circle
Lime mortarStrong lime mortar bound stone and rubble, allowing larger spans
Trabeate to arcuateIndian building was trabeate (beam and lintel); the new style was arcuate (arch and dome). Early buildings mixed both
DecorationIslamic tradition avoided human and animal figures, so ornament used calligraphy (Quranic verses), arabesque (scrolling plant forms) and geometric patterns
MaterialsRed and buff sandstone, with white marble inlay from the Khalji period onwards
Building typesMosques, minarets, tombs (maqbara), madrasas, forts and planned cities
Synthesis, not replacement
The first Sultanate buildings were built by Indian craftsmen, often with material from demolished Hindu and Jain temples. Their carved pillars, lotus and bell motifs and corbelled domes survive inside the mosques. Over time Indian craft skills and Islamic structural ideas fused into a distinct Indo-Islamic style, which the Mughals later carried to its peak.

Phase 1: The Mamluks (13th century)

MonumentPlaceBuilder and dateWhy it matters
Quwwat-ul-Islam MosqueQutb complex, Mehrauli, DelhiBegun by Aibak in the 1190s; extended by Iltutmish and AlauddinAmong the earliest mosques in Delhi; built with temple pillars; has a carved arched screen whose arches are still corbelled, not true. The Gupta-period Iron Pillar stands in its courtyard
Qutb MinarQutb complexBegun by Aibak (c. 1199); completed by Iltutmish (c. 1220); top storey replaced by two storeys under Firuz Shah Tughlaq after lightning in 136872.5 m, five storeys, fluted, with projecting balconies and calligraphic bands. The Qutb complex is a UNESCO World Heritage Site (1993)
Adhai Din ka JhonpraAjmerBegun under Aibak in the 1190s; Iltutmish added the arched screen in the 1220sEarly mosque using temple material; name means “hut of two and a half days” (popular legend about its speed of construction)
Sultan GarhiMalikpur, DelhiIltutmish, c. 1231 (dates vary) for his son Nasiruddin MahmudRegarded as the first Islamic tomb (mausoleum) in India; burial chamber in an underground vault
Tomb of IltutmishQutb complexc. 1235Richly carved interior with calligraphy; built by Iltutmish himself
Tomb of BalbanMehraulic. 1287Where the first true arch in India appears. Its dome has not survived

Phase 2: The Khaljis (c. 1290–1320)

MonumentBuilderWhy it matters
Alai DarwazaAlauddin, 1311Southern gateway of the Quwwat-ul-Islam mosque; red sandstone with white marble inlay; horseshoe-shaped arches; earliest surviving true dome in India, built on true Islamic principles
Alai MinarAlauddinPlanned to be twice the height of the Qutb Minar; left unfinished at the first storey after his death
SiriAlauddinNew fortified city of Delhi built against the Mongols
Hauz-i-Alai (Hauz Khas)AlauddinLarge reservoir for Siri; Firuz Shah later cleaned it and built a madrasa and his own tomb on its bank

Phase 3: The Tughlaqs (1320–1414)

Style: austere and massive. Sloping (battered) walls, rubble masonry covered with plaster, little ornament. Reasons suggested: the military temper of the age, shortage of funds after Muhammad bin Tughlaq, and Firuz Shah’s orthodoxy.

Khirki Masjid and Kalan MasjidKhan-i-Jahan Junan Shah, Firuz’s wazirCovered and enclosed mosque designs

Phase 4: The Sayyids and Lodis (1414–1526)

  • Octagonal tombs for Sultans (for example, those of Mubarak Shah and Muhammad Shah of the Sayyids), with a verandah of arches, sloping buttresses and chhatris (kiosks) on the roof.
  • Square tombs for nobles, such as the Bara Gumbad in the Lodi Gardens.
  • Tomb of Sikandar Lodi (1517–18), built by his son Ibrahim: octagonal, set in a walled enclosure, often called the first garden tomb of the region, and an early example of the double dome (an inner dome and a taller outer shell). The fully developed double dome appears later in Humayun’s Tomb.
Provincial styles (one line each)
As the Sultanate weakened, regional kingdoms built in their own idioms: Jaunpur (Sharqi: monumental mosque gateways such as the Atala Masjid), Gujarat (Ahmedabad: heavy use of temple-style carving and jali), Malwa (Mandu), Bengal (brick and curved roofs) and the Bahmani Deccan. These are optional depth for Mains.

Amir Khusrau (अमीर ख़ुसरो), c. 1253–1325

  • Poet, musician and courtier who served several Sultans from Balban’s time to Ghiyasuddin Tughlaq. Called Tuti-i-Hind (“Parrot of India”).
  • A disciple of the Chishti Sufi Nizamuddin Auliya of Delhi.
  • Wrote in Persian and in Hindavi, the early form of Hindi–Urdu; riddles (paheliyan) and couplets in Hindavi are attributed to him.
  • In Nuh Sipihr he praises India, its languages and its learning.
  • Associated with the development of qawwali and other forms of Hindustani music.
Sitar and tabla: say 'traditionally credited'
Popular books say Khusrau invented the sitar and tabla. Modern scholars reject this: no source from his time mentions either instrument by name, and the credit may come from confusion with an 18th-century musician of a similar name. In an MCQ, “traditionally credited” is the safe reading; in Mains, mention that the claim is disputed.

Other literary developments

  • Persian became the language of administration and high culture.
  • Hindavi / Hindustani developed as a spoken link language in the towns and in Sufi circles.
  • Sanskrit works were translated into Persian under Firuz Shah.
  • Regional literatures flourished in the provinces and in Bhakti poetry (see Bhakti and Sufi Movements).

Chhattisgarh Angle

Temple building continued in Chhattisgarh
While Delhi built in the new arcuate style, temple architecture in Chhattisgarh continued in the older tradition under regional dynasties: the Madwa Mahal (1349) of the Phani Nagavanshis near Bhoramdeo and temples of the Kalachuri period in the plains. A Mains answer on Indo-Islamic architecture can note that the new style was concentrated in Sultanate centres, while forest kingdoms of central India kept the nagara temple tradition alive. See Kalachuri Art and Architecture and Temples and Monuments of Chhattisgarh.

Memory Tricks

The 'firsts' ladder: 'Sultan Built A Sikandar'
  • Sultan Garhi (c. 1231): first tomb
  • Balban’s tomb (c. 1287): first true arch
  • Alai Darwaza (1311): first surviving true dome
  • Sikandar Lodi’s tomb (1517–18): early double dome, first garden tomb of the region

The order S → B → A → S is also the chronological order: tomb, then arch, then dome, then double dome.

Tughlaq style in three words
Slope, Stone-rubble, Simple. Sloping walls, rubble masonry, little ornament.

Don’t Confuse

ThisvsThat
Qutb Minar: begun by Aibak, completed by IltutmishvsAlai Minar: Alauddin’s unfinished tower
Alai Darwaza: gateway, 1311, true domevsBuland Darwaza: Akbar, Fatehpur Sikri (Mughal)
Barani’s Tarikh-i-Firuz ShahivsAfif’s Tarikh-i-Firuz Shahi (same title) and Firuz’s own Futuhat-i-Firuz Shahi

Sultan Garhi: tomb of Iltutmish’s sonvsIltutmish’s own tomb: Qutb complex
Corbelled arch: stepped stones, IndianvsTrue arch: voussoirs and keystone, Islamic

Common Mistakes

MCQ traps
  • “The Qutb Minar was completed by Aibak.” He began it; Iltutmish completed it, and Firuz Shah rebuilt the top after 1368.
  • “Alai Darwaza has the first true arch in India.” The first true arch is in Balban’s tomb; Alai Darwaza has the earliest surviving true dome.
  • “The Quwwat-ul-Islam screen has true arches.” Its early arches are corbelled, made by Indian masons.
  • “Amir Khusrau wrote the Tarikh-i-Firuz Shahi.” That was Barani (and Afif).
  • “Tughlaq buildings are richly decorated.” They are known for austerity.

Level 3: Mains Answer Writing

Q1. (150–200 words) Discuss the main features of Indo-Islamic architecture under the Delhi Sultanate, with examples.

Model answer outline
  • Intro: The Sultanate brought new structural principles that fused with Indian craft to create Indo-Islamic architecture.
  • Structural features: true arch (Balban’s tomb), true dome (Alai Darwaza, 1311), lime mortar, arcuate replacing trabeate; minarets (Qutb Minar).
  • Decoration: calligraphy, arabesque, geometric patterns; red sandstone with white marble from the Khaljis onwards.
  • Phases: Mamluk (Quwwat-ul-Islam, Qutb Minar, Sultan Garhi); Khalji (Alai Darwaza, Siri); Tughlaq (sloping walls, Tughlaqabad, Firuzabad); Lodi (octagonal tombs, early double dome, garden tomb).
  • Synthesis: Indian masons, temple material and motifs (lotus, bell, corbelled screen arches) inside Islamic forms.
  • Chhattisgarh angle (one line): contemporary Chhattisgarh kept the nagara temple tradition (Madwa Mahal, 1349), showing how regional the new style remained.
  • Conclusion: the Sultanate laid the technical and aesthetic base for Mughal architecture.

Q2. (60 words) Write a short note on Amir Khusrau.

Model answer outline
