Nizari Ismaili State
The Nizari state (the Alamut state) was a Shia Nizari Ismaili state founded by Hassan-i Sabbah after he took control of the Alamut Castle in 1090 AD, which marked the beginning of an era of Ismailism known as the "Alamut period". Their people were also known as the ''Assassins'' or ''Hashashins''. The state consisted of a nexus of strongholds throughout Persia and Syria, with their territories being surrounded by huge swathes of hostile territory. It was formed as a result of a religious and political movement of the minority Nizari sect supported by the anti-Seljuk population. Being heavily outnumbered, the Nizaris resisted adversaries by employing strategic, self-sufficient fortresses and the use of unconventional tactics, notably assassination of important adversaries and psychological warfare. Despite being occupied with survival in their hostile environment, the Ismailis in this period developed a sophisticated outlook and literary tradition. Almost two centuries after ...

Mu'ayyad Al-Din Al-Urdi
Al-Urdi (full name: Moayad Al-Din Al-Urdi Al-Amiri Al-Dimashqi) () (d. 1266) was a medieval Syrian Arab astronomer and geometer. Born circa 1200, presumably (from the nisba ''al‐ʿUrḍī'') in the village of ''ʿUrḍ'' in the Syrian desert between Palmyra and Resafa, he came to Damascus at some point before 1239, where he worked as an engineer and teacher of geometry, and built instruments for al-Malik al-Mansur of Hims. In 1259 he moved to Maragha in northwestern Iran, after being asked by Nasir al-Din al-Tusi to help establish the Maragha observatory under the patronage of Hulagu.PDF version Al-Urdi's most notable works are ''Risālat al-Raṣd'', a treatise on observational instruments, and ''Kitāb al-Hayʾa'' (كتاب الهيئة), a work on theoretical astronomy. His influence can be seen on Bar Hebraeus and Qutb al-Din al-Shirazi, in addition to being quoted by Ibn al-Shatir. Al-Urdi contributed to the construction of the observatory outside of the city, constructin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waqf
A waqf ( ar, وَقْف; ), also known as hubous () or '' mortmain'' property is an inalienable charitable endowment under Islamic law. It typically involves donating a building, plot of land or other assets for Muslim religious or charitable purposes with no intention of reclaiming the assets. A charitable trust may hold the donated assets. The person making such dedication is known as a ''waqif'' (a donor). In Ottoman Turkish law, and later under the British Mandate of Palestine, a ''waqf'' was defined as usufruct state land (or property) from which the state revenues are assured to pious foundations. Although the ''waqf'' system depended on several hadiths and presented elements similar to practices from pre-Islamic cultures, it seems that the specific full-fledged Islamic legal form of endowment called ''waqf'' dates from the 9th century AD (see below). Terminology In Sunni jurisprudence, ''waqf'', also spelled ''wakf'' ( ar, وَقْف; plural , ''awqāf''; tr, vak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Möngke Khan
Möngke ( mn, ' / Мөнх '; ; 11 January 1209 – 11 August 1259) was the fourth khagan-emperor of the Mongol Empire, ruling from 1 July 1251, to 11 August 1259. He was the first Khagan from the Toluid line, and made significant reforms to improve the administration of the Empire during his reign. Under Möngke, the Mongols conquered Iraq and Syria as well as the kingdom of Dali (modern-day Yunnan). Appearance According to William of Rubruck, Möngke Khan was a man of medium height. Early life Möngke was born on 11 January 1209, as the eldest son of Genghis Khan's teenaged son Tolui and Sorghaghtani Beki. Teb Tengri Khokhcuu, a shaman, claimed to have seen in the stars a great future for the child and bestowed on him the name Möngke, "eternal" in the Mongolian language. His uncle Ögedei Khan's childless queen Angqui raised him at her orda (nomadic palace). Ögedei instructed Persian scholar Idi-dan Muhammed to teach writing to Möngke.

Baghdad
Baghdad (; ar, بَغْدَاد , ) is the capital of Iraq and the second-largest city in the Arab world after Cairo. It is located on the Tigris near the ruins of the ancient city of Babylon and the Sassanid Persian capital of Ctesiphon. In 762 CE, Baghdad was chosen as the capital of the Abbasid Caliphate, and became its most notable major development project. Within a short time, the city evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many c ...

Siege Of Baghdad (1258)
The siege of Baghdad was a siege that took place in Baghdad in 1258, lasting for 13 days from January 29, 1258 until February 10, 1258. The siege, laid by Ilkhanate Mongol forces and allied troops, involved the investment, capture, and sack of Baghdad, which was the capital of the Abbasid Caliphate at that time. The Mongols were under the command of Hulagu Khan, brother of the khagan Möngke Khan, who had intended to further extend his rule into Mesopotamia but not to directly overthrow the Caliphate. Möngke, however, had instructed Hulagu to attack Baghdad if the Caliph Al-Musta'sim refused Mongol demands for his continued submission to the khagan and the payment of tribute in the form of military support for Mongol forces in Persia. Hulagu began his campaign in Persia against the strongholds of Nizari Ismailis, who lost their stronghold of Alamut. He then marched on Baghdad, demanding that Al-Musta'sim accede to the terms imposed by Möngke on the Abbasids. Although the A ...

Vizier
A vizier (; ar, وزير, wazīr; fa, وزیر, vazīr), or wazir, is a high-ranking political advisor or minister in the near east. The Abbasid caliphs gave the title ''wazir'' to a minister formerly called ''katib'' (secretary), who was at first merely a helper but afterwards became the representative and successor of the ''dapir'' (official scribe or secretary) of the Sassanian kings. In modern usage, the term has been used for government ministers in much of the Middle East and beyond. Several alternative spellings are used in English, such as ''vizir'', ''wazir'', and ''vezir''. Etymology Vizier is suggested to be an Iranian word, from the Pahlavi root of ''vičir'', which originally had the meaning of a ''decree'', ''mandate'', and ''command'', but later as its use in Dinkard also suggests, came to mean ''judge'' or ''magistrate''. Arthur Jeffery considers the word to be a "good Iranian" word, as has a well-established root in Avestan language. The Pahlavi ''viči ...

Alamut Castle
Alamut ( fa, wikt:الموت, الموت, meaning "eagle's nest") is a ruined mountain fortress located in the Alamut region in the South Caspian Sea, Caspian province of Qazvin near the Masudabad, Qazvin, Masoudabad region in Iran, approximately 200 km (130 mi) from present-day Tehran. In 1090 AD, the Alamut Castle, a mountain fortress in present-day Iran, came into the possession of Hassan-i Sabbah, a champion of the Nizari Isma'ilism, Nizari Ismaili cause. Until 1256, Alamut functioned as the headquarters of the Nizari Ismaili state, which included a series of List_of_Ismaili_strongholds, strategic strongholds scattered throughout Persia and Syria, with each stronghold being surrounded by swathes of hostile territory. Alamut, which is the most famous of these strongholds, was thought impregnable to any military attack and was fabled for its heavenly gardens, library, and laboratories where philosophers, scientists, and theologians could debate in intellectual freedom. ...

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 dismantled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbasid Caliphate
The Abbasid Caliphate ( or ; ar, الْخِلَافَةُ الْعَبَّاسِيَّة, ') was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abdul-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH). The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph Al-Mansur founded the city of Baghdad, near the ancient Babylonian capital city of Babylon. Baghdad became the center of science, culture and invention in what became known as the Golden Age of Islam. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the ...
