Maymun-Diz

Maymun-Diz 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 Maymun-Diz rather than just read about it. In short: Maymūn-Diz (Persian: میمون دز) was a major fortress of the Nizari Ismailis of the Alamut Period described in historical records. It has been variously identified with the Alamut Castle, Navizar Shah Castle, Shirkuh Castle, Shahrak Castle, and Shams Kalayeh Cave.

Key takeaways

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

Reference excerpt

Maymūn-Diz (Persian: میمون دز) was a major fortress of the Nizari Ismailis of the Alamut Period described in historical records. It has been variously identified with the Alamut Castle, Navizar Shah Castle, Shirkuh Castle, Shahrak Castle, and Shams Kalayeh Cave. Recently, Enayatollah Majidi located it on top of Mount Shatan (کوه شاتان Kūh-e Shātān; 36.4762463°N 50.6069645°E / 36.4762463; 50.6069645) near Khoshk Chal. The fortress was capitulated by Imam Rukn al-Din Khurshah, who was residing there, to the invading Mongols under Hulagu and was subsequently demolished. This was followed by capitulation of Alamut and the disestablishment of the Nizari state.

History

The date of the (beginning of the) construction by the Nizari Ismailis is variously given as 1097 (per Jami' al-tawarikh), 1103 (per Zubdat al-Tawarikh), and during the Imamate of Ala al-Din Muhammad (1211–1255) (per Tarikh-i Jahangushay). The fortress was on a great spur of rock rising almost vertically from the valley. Its ramparts were made of plaster and gravel. Elsewhere it has been described as an "extraordinary cave-fortress". After the Mongol invasion of Iran and the subsequent death of the last Khwarezmian emperor, Hulagu Khan began to conquer the strongholds of the Nizari Ismailis as the main objective. He demanded the Nizari Imam Rukn al-Din Khurshah dismantle the Nizari fortresses, including Alamut, and surrender himself to Hulagu Khan, who had reached Rudbar. Khurshah was residing in Maymun-Diz, and soon found the fortress encircled by Hulagu Khan and his eight tümens (80,000 fighters). Teams of hand-picked Mongol fighters were distributed at around 250 meters intervals from the hilltop down to the valley. Apparently, the Mongols were hesitant to push the siege of Maymun-Diz, and were persuaded to accept some sort of compromise. As winter was approaching, the besieging Mongols faced supply problems due to the difficulty of finding fodder for their horses. On 19 November 1256, Khurshah with a group of notables left the fortress and surrendered to Hulagu Khan. Considering how well-fortified and well-provisioned Alamut was, the Mongols welcomed the surrender. A group of Nizaris kept fighting in a last stand in the "qubba" (a supposedly high domed structure within the fort) and were killed. Maymun-Diz was subsequently destroyed and its inhabitants were massacred. This is traditionally considered the date of the disestablishment of the Nizari Ismaili state.

Worked examples

Example 1 — a first encounter with Maymun-Diz

Start with the simplest possible case. Write down what Maymun-Diz 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 Maymun-Diz 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 Maymun-Diz 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 Maymun-Diz

In research: Maymun-Diz 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 Maymun-Diz 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: Maymun-Diz is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1256 disestablishments in Asia, 7th-century fortifications, Alamut, so understanding it makes those chapters shorter.
In everyday life: Look for Maymun-Diz 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.

Frequently asked questions

What is Maymun-Diz in simple terms?

Why does Maymun-Diz matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Maymun-Diz?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
