Siri Fort

Siri Fort is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Siri Fort rather than just read about it. In short: Siri Fort, in the city of Delhi, was built during the rule of Alauddin Khalji, second ruler of Khalji Dynasty, of Delhi Sultanate to defend the city from the onslaught of the Mongols. It was the second of the seven cities of medieval Delhi built around 1303 which at present is seen only in ruins with a few remnants due to its poor quality construction as compared to previous fort constructions in India (pictured).

Key takeaways

  • Siri Fort belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Siri Fort to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Siri Fort from memory before moving on to harder problems.

Reference excerpt

Siri Fort, in the city of Delhi, was built during the rule of Alauddin Khalji, second ruler of Khalji Dynasty, of Delhi Sultanate to defend the city from the onslaught of the Mongols. It was the second of the seven cities of medieval Delhi built around 1303 which at present is seen only in ruins with a few remnants due to its poor quality construction as compared to previous fort constructions in India (pictured). Near the Siri Fort ruins, modern auditoriums, the Asian Games Village Complex and residential and commercial establishments fill the modern landscape between the Khel Gaon Marg and the Aurobindo Marg in the heart of South Delhi.

History Alauddin is the best known of the Khalji dynasty because he extended his dominion to Southern India and established the second city of Delhi, Siri. He created Siri between 1297 and 1307 to defend against Mongol invasions of India and Delhi. In response, he built Siri Fort, mimicked massive Turkish ones. The Fort served as the seat of his power during his campaigns to enlarge his territory. Due to frequent Mongol invasions of West Asia, the Seljuqs took asylum in Delhi. The craftsmen of the Seljuq dynasty are credited with this era's architectural monuments in Delhi. In 1303, Targhi, a Mongol general, besieged the Siri fort when Alauddin retreated during the Mongol expedition into India. Targhi could not penetrate the fortifications of the Siri Fort and he finally retreated to his Kingdom in Central Asia. Subsequently, Alauddin's forces defeated Mongols decisively at Amroha (1306). Siri, which is now a part of New Delhi, was later linked to the fortifications of Jahanpanah. Siri was then also known as "Darul Khilafat" or ‘’Seat of Califate’’ In AD 1398, Timurlane, the Mongol ruler who invaded Delhi, wrote in his memoirs, " the Siri is around the city. Its buildings are lofty. They are surrounded by fortifications built of stone and brick, and they are very strong – from the fort of Siri to that of Old Delhi, which is a considerable distance – there runs a strong wall built of stone and cement. The part called Jahanpanah is situated in the midst of the inhabited city. The fortifications of the three cities (Old Delhi, Siri and Tughlaqabad) have thirty gates. Jahanpanah has thirteen gates, Siri has seven gates. The fortifications of the old Delhi have ten gates, some opening to the exterior and some towards the interior of the city."

Legend According to the legend of Ala-ud-din’s war exploits, the name Siri given to the Fort was because the foundation of the fort was built on the severed heads (‘Sir’ in Hindustani means "head") of about 8,000 Mongol soldiers killed in the war.

Structure

Siri Fort was built 5 km (3.1 mi) to the north-east of the Qutab Minar on an old camp near Delhi. The first city is considered to be built by Muslims, it was in an oval shape; its ruins are presently seen in an area of about 1.7 km2 (0.7 mi2). Allauddin, the second ruler of the Khalji dynasty, laid the foundation for the City of Siri in 1303 AD. The structures built in Siri were stated to have had a fine imprint of the enthusiasm of the rulers of Khalji dynasty (particularly, the first three out of six Rulers of the Dynasty) with Allauddin's deep interests in architecture and his achievements supported by the imported skills of the artists of Seljuqs richly contributing to the efforts to build the new city. Legend states that Allauddin's prolific building involved engagement of 70,000 workers. The city was built with an oval plan with palaces and other structures. There were seven gates for entry and exit, but at present only the south-eastern gate exists. The fort was once considered the pride of the city for its palace of a thousand pillars called the Hazar Sutan. The palace was built outside the fort limits, and had marble floors and other stone decoration. Its Darwaza (door) is supposed to have been beautifully decorated. In eastern part of the ruins there are remnants of flame-shaped battlements, loop holes for arrows, and bastions, which were considered unique new additions of that period. In the nearby Shahpur Jat village (pictured), some dilapidated structures of the period are seen. Tohfewala Gumbad Masjid (pictured) is one such structure whose ruins show the form of domed central apartment and sloping wall characteristic of Khaljis architecture. Apart from building the Siri Fort, the citadel around it and the water supply system with a reservoir at Hauz Khas Complex (in present Hauz Khas locality) for providing water supply to Siri, his new city, Ala-ud-din also expanded the building activity around the religious city of the first city complex of Qutb complex by making additions to the Quwwatul-Islam Mosque, which doubled its original size, additions to the Qutub Minar itself (Nagari inscriptions on the tower attribute to this tower as "Vijaya sthamba" or victory tower of Ala-ud-din) and a grandiose plan of constructing a new Minar (tower) bigger (double) that of the Qutub Minar. This plan was left half completed, as may be seen from the ruins at the site, due to the death of Allauddin in 1316. The destruction of the Fort is attributed to the local rulers who removed the fort's stones, bricks and other artifacts for their own buildings. In particular, Sher Shah Suri (1540–1545), of Pashtun Afghan descent from Eastern India (Bihar), took away material from Siri to build his own city. The battered walls of the fort had a wider base on the outside. A protected passage was provided within the battered walls (now seen in ruins as pictured).

Excavation The rest of the structures remained unexplored by archaeologists and these were unknowingly buried when the Asiad Village Complex was built in 1982 for the Asiad 1982.ASI has now launched an excavation programme, since December 2008, to unearth some portions of the wall concealed for centuries which will enable exposing the entire wall providing a continuous link with the earlier excavated stretches of the wall.

Worked examples

Example 1 — a first encounter with Siri Fort

Start with the simplest possible case. Write down what Siri Fort claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Siri Fort before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Siri Fort ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Siri Fort

In research
Siri Fort appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Siri Fort in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Siri Fort is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1303 establishments in Asia, 14th-century establishments in India, Architecture of the Khalji dynasty, so understanding it makes those chapters shorter.
In everyday life
Look for Siri Fort outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
