Siege Of Gurganj
The siege of Gurganj took place during the Mongol conquest of the Khwarazmian Empire. Genghis Khan, ruler of the Mongol Empire, had launched a multi-pronged assault on the Khwarazmian Empire, ruled by Muhammad II of Khwarazm, Shah Muhammad II. Through a combination of efficient planning and excellent manoeuvering, the Khan's army managed to take the border town of Otrar swiftly, followed by the large cities of Siege of Bukhara, Bukhara and Samarkand. Genghis sent a detachment, led by his sons Jochi and Chagatai Khan, Chagatai, northwest to lay siege to the former capital of Gurganj. Immensely wealthy, the city lay on marshy grounds on the river delta, delta of the Amu Darya, making it difficult to assault. The siege was further complicated by disagreements between the two commanding brothers. Eventually, Genghis sent Ogedai, his third son and eventual heir, as sole commander for the siege. When the city was eventually taken, it was annihilated, in one of the bloodiest massacres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongol Conquest Of The Khwarazmian Empire
The Mongol invasion of Khwarezmia ( fa, حمله مغول به خوارزمشاهیان) took place between 1219 and 1221, as troops of the Mongol Empire under Genghis Khan invaded the lands of the Khwarazmian Empire in Central Asia. The campaign, which followed Mongol conquest of the Qara Khitai, the annexation of the Qara Khitai khanate, saw Destruction under the Mongol Empire, widespread devastation and atrocities, and marked the completion of the Mongol conquest of Central Asia, and began the Mongol conquest of Persia. Both belligerents, although large, had been formed recently: the Khwarazmian dynasty had expanded from Khwarazm, their homeland to replace the Seljuk Empire in the late 1100s and early 1200s; near-simultaneously, Genghis Khan Rise of Genghis Khan, had unified the Mongolic peoples and conquered the Mongol conquest of Western Xia, Western Xia dynasty. Although relations were initially cordial, Genghis was angered by a series of diplomatic provocations. When a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Gunpowder
Gunpowder is the first explosive to have been developed. Popularly listed as one of the "Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the Wujing Zongyao, earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout Asia and Europe, possibly as a result of the Mongol conquests during the 13th century, with written formulas for it appearing in the Middle East between 1240 and 1280 in a treatise by Hasan al-Rammah, and in Europe by 1267 in the ''Opus Majus'' by Roger Bacon. It was employed in warfare to some effect from at least the 10th century in weapons such as fire arrows, bombs, and the fire lance before the appearance of the gun in the 13th century. While the fire lance was eventually supplanted by the gun, other gunpowder weapons such as rockets and fire arrows continued to see use in China, Korea, India, and eventually Europe. Bombs too never c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1221 In The Mongol Empire
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amu Darya
The Amu Darya, tk, Amyderýa/ uz, Amudaryo// tg, Амударё, Amudaryo ps, , tr, Ceyhun / Amu Derya grc, Ὦξος, Ôxos (also called the Amu, Amo River and historically known by its Latin name or Greek ) is a major river in Central Asia and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh and Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with " Turan", which roughly corresponded to present-day Central Asia.B. SpulerĀmū Daryā in Encyclopædia Iranica, online ed., 2009 The Amu Darya has a flow of about 70 cubic kilometres per year on average. Names In classical ...

River Delta
A river delta is a landform shaped like a triangle, created by deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. It is so named because its triangle shape resembles the Greek letter Delta. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide coastline defense and can impact drinking water supply. They are also ecologically important, with different species' assemblages depending on their landscape posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siege Of Bukhara
The siege of Bukhara took place during the Mongol conquest of the Khwarazmian Empire, in March 1220. Genghis Khan, ruler of the Mongol Empire, had launched a multi-pronged assault on the Khwarazmian Empire, ruled by Shah Muhammad II. While the Shah planned to defend his major cities individually, the Mongols laid siege to the border town of Otrar, and struck further into Khwarazmia. The city of Bukhara was a major trading and cultural centre of the Khwarazmian Empire, but was located far from the border with the Mongol Empire, and so the Shah allocated fewer than 20,000 soldiers to defend it. However, a Mongol force, estimated to number between 30,000 and 50,000 men, managed to traverse the Kyzylkum Desert, previously thought to be impassable for large armies. Bukhara was caught completely by surprise, and after a failed sortie, the outer city surrendered within three days. Khwarazmian loyalists continued to defend the citadel for less than two weeks, before it was breach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otrar
Otrar or Utrar ( kk, Отырар, ''Otyrar'', otəˈɾɑɾ otk, 𐰚𐰭𐱃𐰺𐰢𐰣, Keŋü Tarman), also called Farab, is a Central Asian ghost town that was a city located along the Silk Road in Kazakhstan. Otrar was an important town in the history of Central Asia, situated on the borders of settled and agricultural civilizations. It was the center of a great oasis and political district, commanding a key point connecting Kazakhstan with China, Europe, Near and Middle East, Siberia and Ural. Names The first known state in the region was known to Chinese scholars as ''Kangju'', which was centered on the Syr Darya (also known as the Kang River). Kangju existed from the 1st century BC until the 5th century AD. Its capital was reportedly at or near Bityan.

Muhammad II Of Khwarazm
Ala ad-Din Muhammad II ( Persian: علاءالدین محمد خوارزمشاه; full name: ''Ala ad-Dunya wa ad-Din Abul-Fath Muhammad Sanjar ibn Tekish'') was the Shah of the Khwarazmian Empire from 1200 to 1220. His ancestor was Anushtegin Gharchai, a Turkic Ghulam who eventually became a viceroy of a small province named Khwarizm. He is perhaps best known for inciting the Mongol conquest of the Khwarazmian Empire, which resulted in the utter destruction of his empire. Reign After his father Tekish died, Muhammad succeeded him. Right after his accession, however, his domains were invaded by the two Ghurid brothers Ghiyath al-Din Ghori and Mu'izz al-Din. Within weeks, the two brothers had moved their armies westwards into Khorasan. Once they had captured Nishapur, Mu'izz al-Din was sent on an expedition towards Ray, but he let his troops get out of control and got little further than Gurgan, earning criticism from Ghiyath which led to the only reported quarrel between the br ...

Siege Engine
A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons (such as ballistae, catapults/ trebuchets and other similar constructions) that attack from a distance by launching projectiles. Some complex siege engines were combinations of these types. Siege engines are fairly large constructions – from the size of a small house to a large building. From antiquity up to the development of gunpowder, they were made largely of wood, using rope or leather to help bind them, possibly with a few pieces of metal at key stress points. They could launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
