Al-Maʿmūn
Abu al-Abbas Abdallah ibn Harun al-Rashid ( ar, أبو العباس عبد الله بن هارون الرشيد, Abū al-ʿAbbās ʿAbd Allāh ibn Hārūn ar-Rashīd; 14 September 786 – 9 August 833), better known by his regnal name Al-Ma'mun ( ar, المأمون, al-Maʾmūn), was the seventh Abbasid caliph, who reigned from 813 until his death in 833. He succeeded his half-brother al-Amin after a civil war, during which the cohesion of the Abbasid Caliphate was weakened by rebellions and the rise of local strongmen; much of his domestic reign was consumed in pacification campaigns. Well educated and with a considerable interest in scholarship, al-Ma'mun promoted the Translation Movement, the flowering of learning and the sciences in Baghdad, and the publishing of al-Khwarizmi's book now known as "Algebra". He is also known for supporting the doctrine of Mu'tazilism and for imprisoning Imam Ahmad ibn Hanbal, the rise of religious persecution ('' mihna''), and for the resum ...

The Compendious Book On Calculation By Completion And Balancing
''The Compendious Book on Calculation by Completion and Balancing'' ( ar, كتاب المختصر في حساب الجبر والمقابلة, ; la, Liber Algebræ et Almucabola), also known as ''Al-Jabr'' (), is an Arabic mathematical treatise on algebra written by the Persian polymath Muḥammad ibn Mūsā al-Khwārizmī around 820 CE while he was in the Abbasid capital of Baghdad, modern-day Iraq. ''Al-Jabr'' was a landmark work in the history of mathematics, establishing algebra as an independent discipline, and with the term "algebra" itself derived from ''Al-Jabr''. The ''Compendious Book'' provided an exhaustive account of solving for the positive roots of polynomial equations up to the second degree. It was the first text to teach algebra in an elementary form and for its own sake. It also introduced the fundamental concept of "reduction" and "balancing" (which the term ''al-jabr'' originally referred to), the transposition of subtracted terms to the other side o ...

Al-Khwarizmi
Muḥammad ibn Mūsā al-Khwārizmī ( ar, محمد بن موسى الخوارزمي, Muḥammad ibn Musā al-Khwārazmi; ), or al-Khwarizmi, was a Persian polymath from Khwarazm, who produced vastly influential works in mathematics, astronomy, and geography. Around 820 CE, he was appointed as the astronomer and head of the library of the House of Wisdom in Baghdad.Maher, P. (1998), "From Al-Jabr to Algebra", ''Mathematics in School'', 27(4), 14–15. Al-Khwarizmi's popularizing treatise on algebra (''The Compendious Book on Calculation by Completion and Balancing'', c. 813–833 CEOaks, J. (2009), "Polynomials and Equations in Arabic Algebra", ''Archive for History of Exact Sciences'', 63(2), 169–203.) presented the first systematic solution of linear and quadratic equations. One of his principal achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications.

House Of Wisdom
The House of Wisdom ( ar, بيت الحكمة, Bayt al-Ḥikmah), also known as the Grand Library of Baghdad, refers to either a major Abbasid public academy and intellectual center in Baghdad or to a large private library belonging to the Abbasid caliphs during the Islamic Golden Age. The House of Wisdom was founded either as a library for the collections of the Caliph Harun al-Rashid in the late 8th century (then later turned into a public academy during the reign of al-Ma'mun) or was a private collection created by al-Mansur (reign 754–775) to house rare books and collections of poetry in Arabic. The House of Wisdom and its contents were destroyed in the Siege of Baghdad in 1258, leaving relatively limited archaeological evidence for the House of Wisdom, such that most knowledge about it is derived from the works of contemporary scholars of the era such as al-Tabari and Ibn al-Nadim.

Graeco-Arabic Translation Movement
The Graeco-Arabic translation movement was a large, well-funded, and sustained effort responsible for translating a significant volume of secular Greek texts into Arabic. The translation movement took place in Baghdad from the mid-eighth century to the late tenth century. While the movement translated from many languages into Arabic, including Pahlavi, Sanskrit, Syriac, and Greek, it is often referred to as the Graeco-Arabic translation movement because it was predominantly focused on translating the works of Hellenistic scholars and other secular Greek texts into Arabic. Pre-Abbasid developments Pre-Islamic developments The ninth king of the Sasanian Empire, Shapur II, established the Academy of Gondishapur, which was to be a medical center, a library, as well as a college where various subjects like anatomy, theology, medicine, and philosophy would be studied. Later, Khosrow I established an observatory that could offer studies in dentistry, architecture, agriculture and irr ...

Fourth Fitna
The Fourth Fitna or Great Abbasid Civil War resulted from the conflict between the brothers al-Amin and al-Ma'mun over the succession to the throne of the Abbasid Caliphate. Their father, Caliph Harun al-Rashid, had named al-Amin as the first successor, but had also named al-Ma'mun as the second, with Khurasan granted to him as an appanage. Later a third son, al-Qasim, had been designated as third successor. After Harun died in 809, al-Amin succeeded him in Baghdad. Encouraged by the Baghdad court, al-Amin began trying to subvert the autonomous status of Khurasan, and al-Qasim was quickly sidelined. In response, al-Ma'mun sought the support of the provincial élites of Khurasan and made moves to assert his own autonomy. As the rift between the two brothers and their respective camps widened, al-Amin declared his own son Musa as his heir and assembled a large army. In 811, al-Amin's troops marched against Khurasan, but al-Ma'mun's general Tahir ibn Husayn defeated them in the Battle ...

Al-Amin
Abu Musa Muhammad ibn Harun al-Rashid ( ar, أبو موسى محمد بن هارون الرشيد, Abū Mūsā Muḥammad ibn Hārūn al-Rashīd; April 787 – 24/25 September 813), better known by his laqab of Al-Amin ( ar, الأمين, al-Amīn), was the sixth Arab Abbasid caliph from 809 to 813. Al-Amin succeeded his father, Harun al-Rashid, in 809 and ruled until he was deposed and killed in 813, during the Fourth Fitna, civil war by his half-brother, al-Ma'mun. Early life and the issue of succession Muhammad, the future al-Amin, was born in April 787 to the Abbasid caliph, Abbasid caliph Harun al-Rashid () and Zubaidah bint Ja`far, Zubayda, herself descended from the second Abbasid caliph, al-Mansur (). Muhammad had an elder half-brother, Abdallah, the future al-Ma'mun (), who had been born in September 786. However, Abdallah's mother was a Persian slave concubine, and his pure Abbasid lineage gave Muhammad seniority over his half-brother. Indeed, he was the only Abbasi ...

Caliph
A caliphate or khilāfah ( ar, خِلَافَة, ) is an institution or public office under the leadership of an Islamic steward with the title of caliph (; ar, خَلِيفَة , ), a person considered a political-religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires. During the medieval period, three major caliphates succeeded each other: the Rashidun Caliphate (632–661), the Umayyad Caliphate (661–750), and the Abbasid Caliphate (750–1258). In the fourth major caliphate, the Ottoman Caliphate, the rulers of the Ottoman Empire claimed caliphal authority from 1517. Throughout the history of Islam, a few other Muslim states, almost all hereditary monarchies such as the Mamluk Sultanate (Cairo) and Ayyubid Caliphate, have claimed to be caliphates. The first caliphate, the Rashidun Caliphate, was established in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Abbasid
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 anno Hegirae, 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 Empire, Babylonian capital city of Babylon. Baghdad became the center of Science in the medieval Islamic world, science, Islamic culture, culture and List of inventions in the medieval Islamic world, invention in what became known as the Islamic Golden Age, Golden Age of Islam.

Regnal Name
A regnal name, or regnant name or reign name, is the name used by monarchs and popes during their reigns and, subsequently, historically. Since ancient times, some monarchs have chosen to use a different name from their original name when they accede to the monarchy. The regnal name is usually followed by a regnal number, written as a Roman numeral, to differentiate that monarch from others who have used the same name while ruling the same realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example Charles X Gustav of Sweden. If a monarch reigns in more than one realm, they may carry different ordinals in each one, as some realms may have had different numbers of rulers of the same regnal name. For example, the same person was both King James VI of Scotland and King James I of England. The ordinal is not normally used for the first ruler of the name, but is used in historical references once the name i ...

Alids
The Alids are those who claim descent from the '' rāshidūn'' caliph and Imam ʿAlī ibn Abī Ṭālib (656–661)—cousin, son-in-law, and companion of the Islamic prophet Muhammad—through all his wives. The main branches are the (including the Ḥasanids, Ḥusaynids, and Zaynabids) and the Alawids. History Primarily Sunnī Muslims in the Arab world reserve the term ''sharīf'' or ''sherīf'' for descendants of Ḥasan ibn ʿAlī, while the term ''sayyid'' is used for descendants of Ḥasan's brother Ḥusayn ibn ʿAlī. Both Ḥasan and Ḥusayn were grandchildren of Muhammad, through the marriage of his cousin ʿAlī ibn Abī Ṭālib and his daughter Fāṭimah. Ever since the post- Hashemite era began, the term ''sayyid'' has been used to denote descendants from both Ḥasan and Ḥusayn. Arab Shīʿa Muslims use the terms ''sayyid'' and ''habib'' to denote descendants from both Ḥasan and Ḥusayn; see . Lines There are several dynasties of Alid or ...
