Girdkuh
Gerdkuh was a castle of the Nizari Isma'ili state located near Damghan in the region of Qumis (modern-day Semnan Province of Iran). Gerdkuh is a "fortified mountain"—a high vertical rock of 300 m in height with buildings on its summit and fortifications at its sides, defended by a triple ring of fortifications at its foot, making the citadel impregnable to direct military assault. It was originally a small fort acquired and refortified in 1096 AD by a Seljuq commander who was secretly a Nizari. The fortress served as a place of refuge for the families of the Nizaris, and its strategic location in the middle of the Khorasan Road made it a useful base for collecting taxes from the passing caravans of the Silk Road. Gerdkuh resisted the Mongol invasion of 1253 AD for 17 years, becoming the last Nizari stronghold in Persia to fall. The fortress remained in use until the early Safavid period. Among the major Nizari fortresses, Gerdkuh is the least studied one. Name The w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongol Campaign Against The Nizaris
The Mongol campaign against the Nizaris of the Alamut period (the Assassins) began in 1253 after the Mongol conquest of the Khwarazmian Empire of Iran by the Mongol Empire and a series of Nizari–Mongol conflicts. The campaign was ordered by the Great Khan Möngke and was led by his brother, Hülegü. The campaign against the Nizaris and later the Abbasid Caliphate was intended to establish a new khanate in the region—the Ilkhanate. Hülegü's campaign began with attacks on strongholds in Quhistan and Qumis amidst intensified internal dissensions among Nizari leaders under Imam Ala al-Din Muhammad whose policy was fighting against the Mongols. His successor Rukn al-Din Khurshah began a long series of negotiations in face of the implacable Mongol advance. In 1256, the Imam capitulated while besieged in Maymun-Diz and ordered his followers to do likewise according to his agreement with Hülegü. Despite being difficult to capture, Alamut ceased hostilities too and was disman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Ismaili Castles
List of the strongholds or dar al-hijra of the Nizari Ismaili state in Persia (Iran) and Syria. Most of the Persian Ismaili castles were in the Alborz mountains, in the regions of Daylaman (particularly, in Alamut and Rudbar; north of modern-day Qazvin) and Quhistan (south of Khurasan), as well as in Qumis. Most of the Syrian Ismaili castles were in Jabal Bahra' (Syrian Coastal Mountain Range). According to Juzjani, before the Mongol invasion the Nizaris possessed 70 forts in Quhistan and 35 in Alamut. Overall, they probably had 250 castles. The Ismaili fortresses in Rudbar of Alamut had been built on rocky heights and were equipped to withstand long sieges; they had storehouses with high capacities and elaborate water supply infrastructure such as cisterns, qanats, and canals.

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Islamic Year
The Hijri calendar ( ar, ٱلتَّقْوِيم ٱلْهِجْرِيّ, translit=al-taqwīm al-hijrī), also known in English as the Muslim calendar and Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual fasting and the annual season for the great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Syriac month-names used in the Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and Palestine) but the religious calendar is the Hijri one. This calendar enumerates the Hijri era, whose epoch was established as the Islamic New Year in 622 CE. During that year, Muhammad and his followers migrated from Mecca to Medina and established the first Muslim community (''ummah''), an event commemorated as the Hijrah. In the West, dates in this era are usually denoted AH ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The son and successor of Malik-Shah I (), he reigned during the opening stages of the decline and fragmentation of the empire, which marked the rise of Turkoman atabegates and principalities, which would eventually stretch from Kirman to Anatolia and Syria.
