By 1000 they had become the chief political and ideological challenge to Sunni Islam and the Abbasids, who by this time had fragmented into several governorships that, while recognizing caliphal authority from Baghdad, remained mostly autonomous. The caliph himself was under 'protection' of the Buyid Emirs who possessed all of Iraq and Western Iran, and were quietly Shia in their sympathies. Outside Iraq, all

These, and many more translations, helped with the advancements in medicine, agriculture, finance, and engineering. Furthermore, new discoveries motivated revised translations and commentary correcting or adding to the work of ancient authors. In most cases names and terminology were changed;

The caliph's immediate family was also executed, with the lone exceptions of his youngest son who was sent to Mongolia, and a daughter who became a slave in the harem of Hulagu. Similarly to how a Mamluk Army was created by the Abbasids, a Mamluk Army was created by the Egypt-based Ayyubid dynasty . These Mamluks decided to directly overthrow their masters and came to power in 1250 in what
756-466: A centre of learning. The Abbasid period was marked by the use of bureaucrats (such as the Barmakid family) for governing the territories as well as an increasing inclusion of non-Arab Muslims in the ummah (Muslim community). Despite this initial cooperation, the Abbasids of the late 8th century had alienated both non-Arab mawali (clients). The political power of the caliphs was limited with
882-531: A collection of fantastical folk tales, legends and parables compiled primarily during the Abbasid era. The collection is recorded as having originated from an Arabic translation of a Sassanian-era Persian prototype, with likely origins in Indian literary traditions. Stories from Arabic , Persian , Mesopotamian, and Egyptian folklore and literature were later incorporated. The epic is believed to have taken shape in
1008-627: A dynasty descended from Muhammad's uncle, Abbas ibn Abd al-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 Revolution had its origins and first successes in the easterly region of Khorasan , far from
1134-501: A living, and an academic life was indicative of high status in society; scientific knowledge was considered so valuable that books and ancient texts were sometimes preferred as war booty rather than riches. Indeed, Ptolemy 's Almagest was claimed as a condition for peace by al-Ma'mun after a war between the Abbasids and the Eastern Roman Empire . The House of Wisdom was much more than an academic center removed from
1260-581: A mosque, all surrounding inner courtyards. Mesopotamia only has one surviving mausoleum from this era, in Samarra: an octagonal domed structured known as the Qubbat al-Sulaibiyya , which is the first known monumental tomb in Islamic architecture and may be the final resting place of al-Muntasir .

His love for science was so great that it was said that he preferred scientific texts as the spoils of war. Furthermore, Abbasid society itself came to understand and appreciate the value of knowledge, and support also came from merchants and the military. It was easy for scholars and translators to make

Only the central lands of Mesopotamia were under direct Abbasid control, with Palestine and the Hejaz often managed by the Tulunids. Byzantium, for its part, had begun to push Arab Muslims farther east in Anatolia . By the 920s, North Africa was lost to the Fatimid dynasty , a Shia sect tracing its roots to Muhammad's daughter Fatimah . The Fatimid dynasty took control of Idrisid and Aghlabid domains, advanced to Egypt in 969, and established their capital near Fustat in Cairo , which they built as
1638-623: A palace library modeled after the Sasanian Imperial Library, and provided economic and political support to the intellectuals working there. He also invited delegations of scholars from India and other places to share their knowledge of mathematics and astronomy with the new Abbasid court. In the Abbasid Empire, many foreign works were translated into Arabic from Greek , Chinese , Sanskrit , Persian and Syriac . The Translation Movement gained great momentum during
1764-665: A physical ruin, or corroborating texts, the phrase "House of Wisdom" may just as well have been a metaphor for the larger Academic community in Baghdad rather than a physical academy specializing in translation work. Gutas mentions that in all of the Graeco-Arabic translations none of them mention the House of Wisdom, including the notable Hunayn ibn Ishaq. There is also no proof that the Sultan ever held open debates among scholars in
1890-455: A place for the preservation of rare books and poetry, a primary function of the House of Wisdom until its destruction. Inside the House of Wisdom, writers, translators, authors, scientists, scribes , and others would meet daily for translation, writing, conversation, reading, and dialogue. Numerous books and documents covering several scientific concepts and philosophical subjects in different languages were translated in this house. Throughout
2016-475: A prime example of this is the title of Ptolemy's Almagest , which is an Arabic modification of the original name of the work: Megale Syntaxis . Besides their translations of earlier works and their commentaries on them, scholars at the Bayt al-Ḥikma produced important original research. For example, the noted mathematician al-Khwarizmi worked in al-Maʾmun’s House of Wisdom and is famous for his contributions to

Maktabs soon began to develop in the city from the 9th century on and, in the 11th century, Nizam al-Mulk founded the Al-Nizamiyya of Baghdad , one of the first institutions of higher education in Iraq. The House of Wisdom flourished under al-Ma'mun's successors al-Mu'tasim (r. 833–842) and his son al-Wathiq (r. 842–847), but considerably declined under
2268-485: A result. Other influential Abbasid philosophers include al-Jahiz , and Ibn al-Haytham (Alhacen). As power shifted from the Umayyads to the Abbasids, the architectural styles changed also, from Greco-Roman tradition (which features elements of Hellenistic and Roman representative style) to Eastern tradition which retained their independent architectural traditions from Mesopotamia and Persia. The Abbasid architecture
2394-431: A vibrant academic community in Baghdad, producing a great number of notable works, regardless of the existence of a formal academy. The fields to which scholars associated with the House of Wisdom contributed include, but are not limited to, philosophy , mathematics , medicine , astronomy , and optics . The early name of the library, Khizanat al-Hikma (literally, "Storehouse of Wisdom"), derives from its function as

Islamic philosophy, in this definition is neither necessarily concerned with religious issues, nor is exclusively produced by Muslims. Their works on Aristotle were a key step in the transmission of learning from ancient Greeks to the Islamic world and the West. They often corrected the philosopher, encouraging a lively debate in
2646-473: Is a strong chance that the library was only used to preserve history from the Sassanian Dynasty and the translations that were done there were only done to achieve that goal. Once the Abbasids took over they most likely continued this tradition with the added goal of pursuing both astrology and astronomy. This is a list of notable people related to the House of Wisdom.

After nearly 250 years of subjection to foreign dynasties, he successfully defended Baghdad against the Seljuqs in the siege of Baghdad (1157) , thus securing Iraq for the Abbasids. The reign of al-Nasir (d. 1225) brought the caliphate back into power throughout Iraq, based in large part on the Sufi futuwwa organizations that the caliph headed. Al-Mustansir built
8316-511: The caliphs were wary of the Alid sympathies in the city and did not always reside here. In 752, al-Saffah built a new city called al-Hashimiyya, at an uncertain location, most likely near Kufa. Later that same year, he moved to Anbar , where he built a new settlement for his Khurasani soldiers and a palace for himself. It was al-Saffah's successor, Abu Ja'far al-Mansur ( r. 754–775 ) who firmly consolidated Abbasid rule and faced down internal challenges. His uncle, Abdallah ibn Ali ,

This city saw 60 years of work, with race-courses and game preserves to add to the atmosphere. Due to the dry remote nature of the environment, some of the palaces built in this era were isolated havens. Al-Ukhaidir Fortress is a fine example of this type of building, which has stables, living quarters, and
8820-422: The civil service. In 794, Jafa al-Barmak built the first paper mill in Baghdad, and from there the technology circulated. Harun required that paper be employed in government dealings, since something recorded on paper could not easily be changed or removed, and eventually, an entire street in Baghdad's business district was dedicated to selling paper and books. One of the common definitions for "Islamic philosophy"
8946-435: The continued repulsing of Byzantine forays. In the 9th century, the Abbasids created an army loyal only to their caliphate, composed of non-Arab origin people, known as Mamluks . This force, created by al-Ma'mun and his brother and successor al-Mu'tasim (833–842), prevented the further disintegration of the empire. The Mamluk army, though often viewed negatively, both helped and hurt the caliphate. Early on, it provided

He studied cryptanalysis but he was also a great mathematician. Al-Kindī is the most famous for being the first person to introduce Aristotle's philosophy to the Arabic people. He fused Aristotle's philosophy with Islamic theology, which created an intellectual platform for philosophers and theologians to debate over 400 years. A fellow expert on Aristotle
9198-534: The downward slide by using non-Muslim mercenaries in his personal army. Also during this period, officers started assassinating superiors with whom they disagreed, in particular the caliphs. By the 870s, Egypt became autonomous under Ahmad ibn Tulun . In the East, governors decreased their ties to the center as well. The Saffarids of Herat and the Samanids of Bukhara began breaking away around this time, cultivating
9324-458: The emphasis was many times put on incorporating new ideas to the ancient works being translated. By the second half of the ninth century, al-Ma'mun's Bayt al-Hikma was the greatest repository of books in the world and had become one of the greatest hubs of intellectual activity during the Medieval era , attracting the most brilliant Arab and Persian minds. The House of Wisdom eventually acquired
9450-473: The empire to the limitless body of early knowledge in the Ancient Near East and Greek traditions, developing the birth of primary scholarship beyond philosophy and scholarship. The engagement across arts and sciences assorts and stretches intelligence realms and brings growth to new methods of understanding. This was accomplished through academic knowledge and creative rehearsal. The House of Wisdom
9576-462: The existence of the House of Wisdom as well as its form and function. He posits in his 1998 book that "House of Wisdom" is a translation error from Khizanat al-Hikma , which he asserts simply means a storehouse, and that there are few sources from the era during the Abbasid Era that mention the House of Wisdom by the name Bayt al-Hikma. Gutas asserts that, without consistent naming conventions,
9702-400: The first Arab paper mill. In time, paper replaced parchment as the medium for writing, and the production of books greatly increased. These events had an academic and societal impact that could be broadly compared to the introduction of the printing press in the West. Paper aided in communication and record-keeping, it also brought a new sophistication and complexity to businesses, banking, and
9828-413: The first astronomical observatories in Baghdad, and he was also the first ruler to fund and monitor the progress of major research projects involving teams of scholars and scientists. In this way he was the first ruler to fund "big science". Following his predecessors, al-Ma'mun would send expeditions of scholars from the House of Wisdom to collect texts from foreign lands. In fact, one of the directors of
9954-428: The first major changes effected by Abbasid rule was the move of the caliphate's center of power from Syria to Mesopotamia (present-day Iraq). This was closer to the Persian mawali support base of the Abbasids and the move addressed their demand for reduced Arab dominance in the empire. However, no definitive capital was yet selected. In these early Abbasid years, Kufa generally served as the administrative capital, but
10080-423: The first time wide-ranging research projects involving large groups of scholars. In order to check Ptolemy's observations, the caliph ordered the construction of the first astronomical observatory in Baghdad (see Observatories section below). The data provided by Ptolemy was meticulously checked and revised by a highly capable group of geographers, mathematicians and astronomers. Al-Ma'mun also organized research on
10206-464: The government with a stable force to address domestic and foreign problems. However, creation of this foreign army and al-Mu'tasim's transfer of the capital from Baghdad to Samarra created a division between the caliphate and the people they claimed to rule. Al-Mu'tasim's reign marked the end of the strong caliphs. He strengthened his personal army with the Mamluks and promptly restarted the war with
10332-566: The growth of scientific knowledge during the golden age of Arabic science. Ideas and wisdom from other cultures around the world, Greece, India, and Persia, were translated into Arabic contributing to further advances in the Islamic Empire. An important goal during this time was to create a comprehensive library that contained all of the knowledge gained throughout this movement. Advances were made in areas like mathematics, physics, astronomy, medicine, chemistry, philosophy, and engineering. The influential achievement of translation revealed to scholars in
10458-539: The knowledge gained from the Roman , Chinese, Indian , Persian , Egyptian , North African, Ancient Greek and Medieval Greek civilizations. According to Huff, "[i]n virtually every field of endeavor—in astronomy, alchemy, mathematics, medicine, optics and so forth—the Caliphate's scientists were in the forefront of scientific advance." The best-known fiction from the Islamic world is One Thousand and One Nights ,
10584-516: The late eight centuries and thirteenth centuries, and most importantly include the references in Ibn al-Nadim 's (d. 995) al-Fihrist . More recently, the narrative of the Abbasid House of Wisdom acting as a major intellectual center, university, and playing a sizable role during the translation movement has been understood by some historians to be a myth, constructed originally over the course of
10710-523: The laws of physics. In the 10th century, Ibn al-Haytham (Alhazen) performed several physical experiments, mainly in optics, achievements still celebrated today. In medicine, Hunayn wrote an important treatise on ophthalmology. Other scholars also wrote on smallpox, infections and surgery. Note that these works would later become standard textbooks of medicine during the European Renaissance. Under al-Ma'mun's leadership science saw for
10836-480: The library and translation center of the House of Wisdom in Baghdad. They began translating ancient Greek into Arabic after quickly mastering the language, as well as paying large sums to obtain manuscripts from the Byzantine Empire for translation. They also made many original contributions to astronomy and physics. Mohammad Musa might have been the first person in history to point to the universality of
10962-511: The library since that would not have been socially acceptable. This theory is debatable, owing to the destruction of the Round city of Baghdad and conflicting sources in both academic texts and poetry. It is likely, given the Abbasid caliphs' patronage of the arts and sciences, that an extensive library existed in Baghdad, and that scholars could have access to such texts, judging by the volume of work produced by scholars centered in Baghdad. There
11088-404: The nineteenth and early twentieth centuries by Orientalists and, through their works, propagated its way into scholarship and nationally-oriented works until more recent re-investigations of the evidence. The House of Wisdom existed as a part of the major Translation Movement taking place during the Abbasid Era, translating works from Greek and Syriac to Arabic , but it is unlikely that
11214-587: The outbreak of fitnas in the capital, often contending with the ayyarun . With the Buyid dynasty on the wane, a vacuum was created that was eventually filled by the dynasty of Oghuz Turks known as the Seljuqs . By 1055, the Seljuqs had wrested control from the Buyids and Abbasids, and took temporal power. When the amir and former slave Basasiri took up the Shia Fatimid banner in Baghdad in 1056–57,
11340-656: The reasons that al-Ma'mun loved the pursuit of knowledge was said to be from a dream that he once had. In the dream, he was said to have been visited by Aristotle , where they had a discussion on what was good. Inspired by Aristotle, al-Ma'mun regularly initiated discussion sessions and seminars among experts in Kalām ; Kalām being an art of philosophical debate, which al-Ma'mun carried on from his Persian tutor, Ja’far. During such debates, scholars would discuss their fundamental Islamic beliefs and doctrines in an open, intellectual atmosphere. He would often organize groups of sages , from
11466-474: The region also appear to have served as "capitals" under either al-Saffah or al-Mansur prior to the founding of Baghdad. Al-Mansur centralised the judicial administration, and later, Harun al-Rashid established the institution of Chief Qadi to oversee it. The Umayyad empire was mostly Arab; however, the Abbasids progressively became made up of more and more converted Muslims in which the Arabs were only one of many ethnicities. The Abbasids had depended heavily on
11592-465: The reign of al-Mutawakkil (r. 847–861). Although al-Ma'mun, al-Mu'tasim, and al-Wathiq followed the sect of Mu'tazili , which supported broad-mindedness and scientific inquiry, al-Mutawakkil endorsed a more literal interpretation of the Qur'an and Hadith . The caliph was not interested in science and moved away from rationalism, seeing the spread of Greek philosophy as anti-Islamic. On February 13, 1258,
11718-448: The reign of Caliph Harun al-Rashid , who, like his predecessor, was personally interested in scholarship and poetry. Originally the texts concerned mainly medicine, mathematics and astronomy; but other disciplines, especially philosophy, soon followed. Al-Rashid's library, the direct predecessor to the House of Wisdom, was also known as Bayt al-Hikma or, as the historian al-Qifti called it, Khizanat Kutub al-Hikma (Arabic for "Storehouse of
11844-520: The return of power to the family of Muhammad, the Hashemites , during the reign of Umar II . During the reign of Marwan II , this opposition culminated in the rebellion of Ibrahim al-Imam , the fourth in descent from Abbas. Supported by the province of Khorasan (Eastern Persia), even though the governor opposed them, and the Shia Arabs, he achieved considerable success, but was captured in
11970-604: The rise of the Iranian Buyids and the Seljuq Turks , who captured Baghdad in 945 and 1055, respectively. Although Abbasid leadership over the vast Islamic empire was gradually reduced to a ceremonial religious function in much of the caliphate, the dynasty retained control of its Mesopotamian domain during the rule of Caliph al-Muqtafi and extended into Iran during the reign of Caliph al-Nasir . The Abbasids' age of cultural revival and fruition ended in 1258 with

12222-470: The second Abbasid caliph al-Mansur ( r. 754–775 ) to house rare books and collections in the Arabic language. During the reign of the seventh Abbasid caliph al-Ma'mun ( r. 813 – 833 AD ), it was turned into a public academy and a library. Finally, it was destroyed in 1258 during the Mongol siege of Baghdad . The primary sources behind the House of Wisdom narrative date between
12348-401: The siege. Many of the books were also torn apart by pillagers so that the leather covers could be made into sandals. The House of Wisdom included a society of scientists and academics, a translation department, and a library that preserved the knowledge acquired by the Abbasids over the centuries. Research and study of alchemy, which was later used to form the structure of modern chemistry,
12474-462: The spirit of ijtihad . They also wrote influential original philosophical works, and their thinking was incorporated into Christian philosophy during the Middle Ages, notably by Thomas Aquinas . Three speculative thinkers, al-Kindi , al-Farabi , and Avicenna , combined Aristotelianism and Neoplatonism with other ideas introduced through Islam, and Avicennism was later established as
12600-528: The support of Persians in their overthrow of the Umayyads. Al-Mansur welcomed non-Arab Muslims to his court. While this helped integrate Arab and Persian cultures, it alienated many of their Arab supporters, particularly the Khorasanian Arabs who had supported them in their battles against the Umayyads. The Abbasid leadership had to work hard in the last half of the 8th century (750–800) under several competent caliphs and their viziers to usher in
12726-613: The title of sultan , as opposed to the "amir" that had been in more common usage, signifying the Ghaznavid Empire 's independence from caliphal authority, despite Mahmud's ostentatious displays of Sunni orthodoxy and ritual submission to the caliph. In the 11th century, the loss of respect for the caliphs continued, as some Islamic rulers no longer mentioned the caliph's name in the Friday khutba , or struck it off their coinage. The Isma'ili Fatimid dynasty of Cairo contested
12852-607: The treaty, then fended off multiple incursions during the first decade of the 9th century. These attacks pushed into the Taurus Mountains , culminating with a victory at the Battle of Krasos and the massive invasion of 806 , led by Rashid himself. Rashid's navy also proved successful, taking Cyprus . Rashid decided to focus on the rebellion of Rafi ibn al-Layth in Khorasan and died while there. Military operations by
12978-597: The victor over the Umayyads at the Battle of the Zab, was the most serious potential rival for leadership and al-Mansur sent Abu Muslim, the Khurasani revolutionary commander, against him in 754. After Abu Muslim successfully defeated him, al-Mansur then turned to eliminate Abu Muslim himself. He arranged to have him arrested and executed in 755. On the western frontier, the Abbasids were unable to re-assert caliphal control over
13104-429: The way animals adapt to their surroundings, similarly to Aristotle's History of Animals . In his book, al-Jāḥiẓ argued that animals like dogs, foxes, and wolves must have descended from a common ancestor because they shared similar characteristics and features such as four legs, fur, tail, and so on. Mūsā ibn Shākir was an astrologer and a friend of Caliph Harun al-Rashid's son, al-Ma'mun. His sons, collectively known as
13230-484: The western and central Maghreb, which the Umayyads had lost in the 740s. One member of the Umayyad dynasty, Abd ar-Rahman, also managed to escape the purge of his family and managed to establish independent in rule in al-Andalus (present-day Spain and Portugal) in 756, founding the Umayyad Emirate of Córdoba . In 756, al-Mansur had also sent over 4,000 Arab mercenaries to assist the Chinese Tang dynasty in
13356-551: The year 747 and died, possibly assassinated, in prison. On 9 June 747 (15 Ramadan AH 129), Abu Muslim , rising from Khorasan, successfully initiated an open revolt against Umayyad rule, which was carried out under the sign of the Black Standard . Close to 10,000 soldiers were under Abu Muslim's command when the hostilities officially began in Merv. General Qahtaba followed the fleeing governor Nasr ibn Sayyar west defeating
13482-408: The youngest uncles of Muhammad and of the same Banu Hashim clan. The Abbasids claimed to be the true successors of Muhammad in replacing the Umayyad descendants of Banu Umayya by virtue of their closer bloodline to Muhammad. The Abbasids also distinguished themselves from the Umayyads by attacking their moral character and administration in general. According to Ira Lapidus , "The Abbasid revolt
13608-602: Was Layla and Majnun , an originally Arabic story which was further developed by Iranian , Azerbaijani and other poets in the Persian , Azerbaijani , and Turkish languages. It is a tragic story of undying love much like the later Romeo and Juliet .

Writers like Abu Tammam and Abu Nuwas were closely connected to
13734-481: Was Abū ʿUthmān al-Jāḥiẓ , who was born in Basra around 776 but he spent most of his life in Baghdad. Al-Ma’mun employed al-Jāḥiẓ as a personal tutor for his children, but he had to dismiss him because al-Jāḥiẓ was "goggled-eyed", i.e., he had wide, staring eyes which made him frightening to look at. Al-Jāḥiẓ was one of the few Muslim scholars who was deeply concerned with biology. He wrote Book of Animals, which discusses
13860-515: Was "The Instrument that Plays by Itself", the earliest example of a programmable machine, as well as the Book on Measurement of Plane and Spherical Figures .

Having shown much potential, the brothers were enrolled in
13986-404: Was also conducted there. Further, it was also linked to astronomical observations and other major experimental endeavors. Institutionalized by al-Ma'mun, the academy encouraged the transcription of Greek philosophical and scientific efforts. Additionally, he imported manuscripts of important texts that were not accessible to the Islamic countries from Byzantium to the library. The House of Wisdom
14112-420: Was also during this period that Islamic manuscript production reached its height. Between the 8th and 10th centuries, Abbasid artisans pioneered and perfected manuscript techniques that became standards of the practice. 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 an international reputation as
14238-415: Was defeated by an Abbasid army led by Isa ibn Musa . It was after this victory, in 762, that al-Mansur finally established a proper Abbasid capital, Baghdad – officially called Madinat al-Salam ('City of Peace') – located on the Tigris River . Prior to this, he had continued to consider multiple sites for a capital, including al-Hashimiyya, which he used as a capital for a while. Various other sites in
14364-490: Was destroyed. Claims have been made that the Tigris ran red from the blood of the scientists and philosophers killed. Citizens attempted to flee, but were intercepted by Mongol soldiers who killed in abundance, sparing no one, not even children. The caliph Al-Musta'sim was captured and forced to watch as his citizens were murdered and his treasury plundered. Ironically, Mongols feared that a supernatural disaster would strike if
14490-465: Was initially akin to a secretary, but under the tenure of the Barmakids , an Iranian family close to the Abbasids, the position became powerful and Harun al-Rashid delegated state affairs to them for many years.

14616-519: Was known for being a space for scholarly growth and contribution which during the time greatly contributed to the Translation Movement. The Translation Movement started in this House of Wisdom and lasted for over two centuries. Over a century and a half, primarily Middle Eastern Oriental Syriac Christian scholars translated all scientific and philosophic Greek texts into Arabic language in the House of Wisdom. The translation movement at
14742-619: Was later to become Baghdad. During the Umayyad era, Muawiyah I started to gather a collection of books in Damascus. He then formed a library that was referred to as "Bayt al-Hikma". Books written in Greek, Latin, and Persian in the fields of medicine, alchemy , physics, mathematics, astrology and other disciplines were also collected and translated by Muslim scholars at that time. The Umayyads also appropriated paper-making techniques from
14868-407: Was lost due to the ephemeral nature of the stucco and luster tiles. Another major development was the creation or vast enlargement of cities as they were turned into the capital of the empire, beginning with the creation of Baghdad in 762, which was planned as a walled city with four gates, and a mosque and palace in the center. Al-Mansur, who was responsible for the creation of Baghdad, also planned
14994-416: Was much more than a library, and a vast amount of original scientific and philosophical work was produced by scholars and intellectuals in relation to it (although many were lost due to the destruction of the library). This allowed Muslim scholars to verify astronomical information that was handed down from past scholars. The Translation Movement lasted for two centuries and was a large contributing factor to
15120-404: Was particularly influenced by Sasanian architecture , which in turn featured elements present since ancient Mesopotamia. The Christian styles evolved into a style based more on the Sasanian Empire , utilizing mud bricks and baked bricks with carved stucco. Other architectural innovations and styles were few, such as the four-centered arch , and a dome erected on squinches . Unfortunately, much
15246-548: Was slowly replaced by a Baramkid bureaucracy. To the west, Harun al-Rashid agreed to grant the province of Ifriqiya (centered in present-day Tunisia) as a hereditary emirate to Ibrahim ibn al-Aghlab , who founded the Aghlabid dynasty there. Al-Mahdi restarted the fighting with the Byzantines , and his sons continued the conflict until Empress Irene pushed for peace. After several years of peace, Nikephoros I broke
15372-466: Was subsequently killed. The remainder of his family, barring one male, were also eliminated. Immediately after their victory, al-Saffah sent his forces to Central Asia , where his forces fought against Tang expansion during the Battle of Talas . Al-Saffah focused on putting down numerous rebellions in Syria and Mesopotamia . The Byzantines conducted raids during these early distractions. One of

The Abbasids also appealed to non-Arab Muslims, known as mawali , who remained outside the kinship-based society of the Arabs and were perceived as a lower class within the Umayyad empire. Muhammad ibn 'Ali , a great-grandson of Abbas, began to campaign in Persia for
15624-539: Was taken away as a prisoner by Selim I to Constantinople where he had a ceremonial role. He died in 1543, following his return to Cairo. The Abbasid historical period lasting to the Mongol conquest of Baghdad in 1258 CE is considered the Islamic Golden Age. The Islamic Golden Age was inaugurated by the middle of the 8th century by the ascension of the Abbasid Caliphate and the transfer of
15750-406: Was the 10-year period of Al-Mu'tadid 's rule ( r. 892–902). He brought parts of Egypt, Syria, and Khorasan back into Abbasid control. Especially after the " Anarchy at Samarra " (861–870), the Abbasid central government was weakened and centrifugal tendencies became more prominent in the caliphate's provinces. By the early 10th century, the Abbasids almost lost control of Iraq to various emirs , and
15876-579: Was the beginning of Arabic science , and drove demand for more and updated translations. The House of Wisdom was made possible by the consistent flow of Arab, Persian, and other scholars of the Islamic world to Baghdad, owing to the city's position as capital of the Abbasid Caliphate. This is evidenced by the large number of scholars known to have studied in Baghdad between the 8th and 13th centuries, such as al-Jahiz , al-Kindi , and al-Ghazali among others, all of whom would have contributed to
