Purana Qila

Purana Qila 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 Purana Qila rather than just read about it. In short: Purana Qila (lit. 'Old Fort') is one of the oldest forts in Delhi, India. It was built by the second Mughal Emperor Humayun and Surid Sultan Sher Shah Suri.

Key takeaways

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

Reference excerpt

Purana Qila (lit. 'Old Fort') is one of the oldest forts in Delhi, India. It was built by the second Mughal Emperor Humayun and Surid Sultan Sher Shah Suri. The fort forms the inner citadel of the city of Dinpanah. It is located near the expansive Pragati Maidan exhibition ground and is separated from Dhyanchand Stadium by Mathura Road, Delhi.

History

Pre-Islamic habitation and Indraprastha theory Excavations point to traces and continued habitation from the 1000 BC, during the Painted Grey Ware period. The first two rounds of excavations – in 1954–55 and 1969–72 – by B. B. Lal, then director of the Archaeological Survey of India (ASI), had unearthed traces of Painted Grey Ware culture. Historian Alexander Cunningham identified the fort with that of Indraprastha, though he referred to the present structure as built by Muslim rulers. Even till the early part of the 20th century, Purana Qila was known as Pandavon Ka Qila (Pandava's fort) and the entire complex as Indraprastha village. It must be remembered that coordinating material archaeological culture with literary and bardic literature is methodologically almost always impossible.

Dinpanah The origins of the Purana Qila lie in the walls of Dinpanah, the new city of Delhi was being constructed by Mughal emperor Humayun, in the general vicinity of the ancient Indraprastha ruins. Abul Fazl stated that he built the fort in the place of that of ancient Indraprastha. The founder of the Sur Empire, Sher Shah Suri, defeated Humayun and made changes to the fort, strengthening its fortifications and completing its walls. He also had another fort built there called Shergarh, where the governor resided. His project, however, was a continuation of Humayun's construction of a citadel for a royal city. He also built many structures inside the fort. Additions to the fort have been believed to have been made even after his rule. The extent of his contribution to the fort's construction is disputed. The historical attribution of its construction is also uncertain judging from primary sources. Muhammad Khwandamir said that Humayun laid the foundation of the city on a mound near Yamuna. The construction of the walls and fortifications were almost finished by Humayun's time. Tarikh-i-Da'udi states that Sher Shah Suri's royal city remained incomplete upon his death and he had named his fort Shergarh. Abbas Sarwani states the two forts being constructed by him were incomplete when he died. Tarikh-i-Khan-Jahan states that Salim Shah Suri had constructed a wall defending Dinpanah of Humayun. Purana Qila and its environs flourished as the "sixth city of Delhi". On 7 October 1556 Hindu king Hem Chandra Vikramaditya, who had defeated Akbar's forces at Battle of Delhi (1556) was crowned in Purana Qila. The Mughals would one month later decisively defeat Hemu and his army at the second battle of Panipat.

British Era Edwin Lutyens who designed the new capital of British India, New Delhi, in the 1920s, had aligned the central vista, now Rajpath, with Purana Qila. During the Partition of India, in August 1947 the Purana Qila along with the neighbouring Humayun's Tomb, became the site for refuge camps for Muslims migrating to newly founded Pakistan. This included over 12,000 government employees who had opted for service in Pakistan, and between 150,000–200,000 Muslim refugees, who swarmed inside Purana Qila by September 1947, when Indian government took over the management of the two camps. The Purana Qila camp remained functional until early 1948, as the trains to Pakistan waited until October 1947 to start.

World War II During the Asia-Pacific War (1941–1945), over 2000 Japanese civilians were interned in British India, of whom around 554 were women and 224 children. Plans to intern Japanese living in British India, along with surveillance of persons of interest, were put into place from as early as July 1940, with preparations to open internment camps made from at least February 1941. After war broke out between Japan and the Allies later that year, Japanese civilians in India, along with those of other now-enemy nations, were joined in internment by civilians from various British colonial territories, including Malaya and Singapore. Two key civilian internment camps in India were Purana Qila, the Old Fort, in Delhi, and Deoli in the deserts of Rajputana. The fate of the Japanese in India threw a shadow over the whole business, and the British believed, with some justification, that the ill-treatment of Allied prisoners of war was a reprisal for this. By December 1942, there were 2,115 Japanese internees, the vast majority from Singapore, in Purana Quila camp outside Delhi. They were housed in tents that gave little protection from the cold in winter, or from temperatures that rose to 120 degrees in summer. The Japanese government protested that the food and the cooking, washing and sanitation facilities were inadequate. The British dismissed this: the Japanese were `notoriously unable to cope with extremes of heat or cold'. (`Treatment of Japanese internees in India', 1z December 1942, F09,6/ 477, PRO.)`According to Asiatic standards', officials observed, the rations were `adequate for proper nourishment'.( R. N. Gilchrist to under secretary of state, Foreign Office, 19 October 1942, ibid)

Recent years In the 1970s, the ramparts of Purana Qila were first used as a backdrop for theatre, when three productions of the National School of Drama were staged here: Tughlaq, Andha Yug and Sultan Razia, directed by Ebrahim Alkazi. In later decades it has been the venue of various important theatre productions, cultural events, and concerts. Today, it is the venue of a daily sound and light presentation after sunset, on the history of the "Seven Cities of Delhi", from Indraprastha through New Delhi.

Worked examples

Example 1 — a first encounter with Purana Qila

Start with the simplest possible case. Write down what Purana Qila 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 Purana Qila 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 Purana Qila 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 Purana Qila

In research
Purana Qila 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 Purana Qila 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
Purana Qila is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1538 establishments in India, 16th-century forts in India, Buildings and structures completed in 1538, so understanding it makes those chapters shorter.
In everyday life
Look for Purana Qila 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.
