Abbasid architecture

Abbasid architecture developed in the Abbasid Caliphate between 750 and 1227, primarily in its heartland of Mesopotamia (modern Iraq).
The great changes of the Abbasid era can be characterized as at the same time political, geo-political and cultural. The Abbasid period starts with the destruction of the Umayyad ruling family and its replacement by the Abbasids, and the position of power is shifted to the Mesopotamian area, and as a result in a corresponding displacement of the influence of classical and Byzantine artistic and cultural standards in favor of local Mesopotamian models as well as Persian. The Abbasids evolved distinctive styles of their own, particularly in decoration of their buildings. They favoured mud brick and baked brick for construction, allowing for enormous architectural complexes to be built at relatively low cost, as most clearly exemplified by Samarra, a 9th-century capital city made up of vast palaces and monumental mosques spread across some .

The architecture of the Abbasid Caliphate was an important formative stage in wider Islamic architecture. The early caliphate's great power and unity allowed architectural features and innovations, such as minarets and carved stucco motifs, to spread quickly across the vast territories under its control. While the Abbasids lost control of large parts of their empire after 870, their architecture continued to be copied by successor states in Iraq, Iran, Egypt and North Africa.

Historical background

In 750 the Abbasids seized power from the Umayyad rulers of the Arab empire, who lost all their possessions apart from Spain. The Abbasid caliphs based in what is now Iraq ruled over Iran, Mesopotamia, Arabia and the lands of the eastern and southern Mediterranean. The period between 750 and 900 has been described as the Islamic Golden Age. Where the Umayyads had typically reused pre-Islamic buildings in the cities they had conquered, by the Abbasid era many of these structures required replacement. The spread of Muslim beliefs had also brought changes in needs. The Abbasids had to build masjid and palaces, as well as fortifications, houses, commercial buildings and even facilities for racing and polo matches. They upgraded the pilgrim road from Baghdad and Kufa to Mecca, levelled the surface and built walls and ditches in some areas, and built stations for the pilgrims with rooms and a mosque in which to pray.

In 762 the caliph al-Mansur founded a new capital of Baghdad on the Tigris, which soon grew to one of the largest cities in the world. In 836 the caliph al-Mu'tasim transferred the capital to Samarra. The Abbasids began to lose control over the outlying parts of the empire, with local dynasties gaining effective independence in Khorasan ( Samanids) in eastern Iran, Egypt (Tulunids) and Ifriqiya (Aghlabids). The caliph al-Mu'tamid, by now the effective ruler only of Iraq, moved his capital back to Baghdad in 889. In 945 the Buyids, followers of Shia Islam, became effective rulers as amirs, while the Abbasid caliphs retained their nominal title. With Caliph al-Nasir (1179-1225) the Abbasids once again gained control of Iraq, but the sack of Baghdad by the Mongols in 1258 brought the Abbasid caliphate to an end.

Origins

Early Abbasid architecture was strongly influenced by the architecture of the earlier Sassanid Empire, as exemplified by the Palace of Ukhaidhir. The former Sassanid capital had been Ctesiphon in present-day Iraq and Sasanian architecture was a heritage shared by both the Mesopotamian lowlands and the Iranian plateau. The Abbasids used the same techniques, such as vaulting made without centring, similar design features, such as buttress towers, and the same materials, such as mud brick, baked brick and rough stone blocks set in mortar. Stone is rare in the central and southern alluvial plains that formed the heartland of Abbasid territory, so many of the buildings were of mud-brick, faced with plaster and frequently repaired or rebuilt. Sometimes fired brick was used. When the caliph al-Mansur built the round city of Baghdad, called ''Madinat al-Salam'', he may have been following earlier traditions such as the round city of Gur built by Ardashir I (r. 224-241) at Firuzabad. It contained the caliphal palace, a Great Mosque and administrative buildings.

Early Abbasid architecture was also influenced by ancient Mesopotamian architecture, whose features continued to be present in the region's structures even after centuries of occupation by Roman, Greek, and Iranian empires. This Mesopotamian influence in Islamic architecture was only diluted in the 10th century, when Abbasid Mesopotamia entered a period of economic decline and the centers of political power in the region shifted east to Iran.

With the conquest of Central Asia, the influence of Soghdian architecture increased. In Samarra the stucco and wall paintings are similar to that of the palaces of Panjakent in what is now Tajikistan. Later, in the 12th and 13th centuries, architecture in the lands ruled by the Abbasids became dominated by Seljuk architecture.

Innovations

Abbasid cities were laid out on huge sites. The palaces and mosques of Samarra sprawled along the shores of the Tigris for . To match the scale of the sites, monumental buildings were erected, such as the huge spiral minarets of the Abu Dulaf Mosque and the Great Mosque of Samarra, which had no counterparts elsewhere. While the origins of the minaret are still uncertain, these and several other early 9th-century minarets built within the Abbasid territories are the first true minarets in Islamic architecture. The two-centered pointed arch and vault had appeared before the Abbasids took power, but became standard in Abbasid architecture, with the point becoming more prominent. The first fully developed example of the four-centered pointed arch was at the Qasr al-'Ashiq, built between 878 and 882.

Three new types of stucco decoration were developed in Samarra and rapidly became popular elsewhere. The first two styles may be seen as derivative from Late Antique or Umayyad decorative styles, but the third is entirely new. Style C used molds to create repeating patterns of curved lines, notches, slits, and other elements. The fluid designs make no use of traditional vegetal, geometric or animal themes. The stucco work was sometimes colored in red or blue, and sometimes incorporated a glass mosaic. The patterns cut into the stucco surface at an angle. This is the first and purest example of the arabesque. It may represent a deliberate attempt to make an abstract form of decoration that avoids depiction of living things, and this may explain its rapid adoption throughout the Muslim world.

The layout of the Fatimid city of Al-Mansuriya in Ifriqiya founded in 946 was circular, perhaps in imitation of Baghdad. The choice of layout may have been a deliberate challenge to the Abbasid Caliphate. The Fatimid architecture of Ifriqiya and Egypt followed Abbasid styles, as shown by the Great Mosque of Mahdiya and the Azhar Mosque in Cairo. Even Umayyad buildings of the Iberian peninsula show Abbasid influence.

Characteristics

Typical features of the more important buildings included massive round piers and smaller engaged columns. 9th century Abbasid architecture had foliate decorations on arches, pendant vaults, ''muqarnas'' vaults and polychrome interlaced spandrels that became identified as typical of "Islamic" architecture, although these forms may have their origins in Sassanian architecture. Thus the fronting arch of the Arch of Ctesiphon was once decorated with a lobed molding, a form copied in the Palace of al-Ukhaidir.

Palaces

The earliest surviving Abbasid palace, built around 775, is the al-Ukhaidir Palace. It has a plan derived from earlier Sasanian and Umayyad palaces. The palace lies in the desert about to the south of Baghdad. It is rectangular in shape, , with four gates. Three are in half-round towers that protrude from the wall, and one in a rectangular recess in the wall. Inside there is a vaulted entrance hall, a central court, an iwan (hall) open to the court opposite the entrance hall, and residential units. Sasanian techniques persist in the construction of vaults with pointed curves using rubble and mortar faced with brick and stucco, blind arches as decorations for large wall surfaces, and long vaulted halls with recesses behind arches supported by heavy pillars. Verbal descriptions indicate that palaces in Baghdad had similar layout, although on a larger scale.

In 772 Al-Mansur founded a new city called al-Rafiqa on the Euphrates, the site of present-day Raqqa. The city was laid out in the shape of a horseshoe and reportedly copied the Round City of Baghdad. Later, Harun al-Rashid made the city his capital during the later years of his reign and built his residence here between 796 and 808. Some of its remains have been excavated, revealing buildings with spacious floor plans similar to other parts of Mesopotamia but lacking the use of iwans. The Baghdad Gate, one of the few old monuments preserved in Raqqa today, was once thought to date from al-Mansur's foundation in the late 8th century, but it has since been attributed to the 11th or 12th century instead, around the time of Numayrid or Zengid rule.

The palaces of Samarra, founded by al-Mu'tasim in 836, were notable for their enormous size and their well-defined subdivisions. They included vast courtyards around which numerous apartments and halls were arranged. Some of the palaces had multiple monumental gates, arranged in succession, which granted access from one courtyard to another. Al-Mu'tasim's main palace, known as the ''Dār al-Khilāfa'' or the ''Jawsaq al-Khāqānī'', was begun around the same time as the city's foundation. On its west side was a grand entrance overlooking the Tigris River. It consisted of a grand staircase leading up to a monumental gate in the form of a three iwans, known as ''Bab al-'Amma''. At the foot of the staircase was a large rectangular water basin from which a canal led down to a raised pavilion near the river, 300 meters away from the gate. The gate itself had a second story from which the caliph, the palace residents, or the guards were able to survey the landscape. Behind the gate, a series of halls led eastward to a square courtyard. Beyond this was a domed hall with four iwans arranged in a cruciform layout, with each iwan granting access to another courtyard behind it. The eastern courtyard beyond this was a vast esplanade measuring which had water channels, fountains, and possibly gardens. Among other excavated and partly reconstructed features visible today is a sunken courtyard with chambers constructed around a large circular water basin, the so-called "Large Serdab" (as named by Ernst Herzfeld) or ''Birka Handasiyya'' ("Geometric Basin", a name given by Iraqi archeologists). The courtyard, located to the north of the grand esplanade, was probably designed to be a respite from the heat of summer. In addition to the main palace, Al-Mutawakkil built luxurious palaces for his sons, such as the Balkuwara Palace for his son al-Mu'tazz, which had a style and layout similar to the ''Dar al-Khilafa''. Samarra's extensive facilities also included barracks, stables and racecourses.

Palaces at Samara such as al-'Ashiq and al-Jiss, built around 870, display polylobed moldings carved deeply into the intrados of the arches, giving the appearance of a foliate arch. Floors were sometimes of marble, more often tiled. The reception rooms of palaces at Samarra had carved or molded stucco dados decorating the lower part of the walls, and stucco also decorated door frames, wall-niches and arches, in three distinct styles. Other palaces that have been excavated often have a domed central chamber surrounded by four iwans facing outward.

The only potential Abbasid palace structure left in Baghdad is located in the Al-Maiden neighborhood overlooking the Tigris, in what was formerly the citadel of the city. Popularly known as the "Abbasid Palace", the origins and nature of the structure have been debated by scholars, as there are no surviving inscriptions or texts that identify its name or function. The building was erected under Caliph al-Nasir li-Din Allah (r. 1180–1225) or possibly al-Mustansir (r. 1226–1242), in the late Abbasid period. It stands two stories high and contains a central courtyard and an iwan with a brick ceiling and façade. One of its most unique features is the series of ''muqarnas'' vaults that decorate the inside of its eastern gallery. Its design shares close similarities with the Al-Mustansiriya Madrasa (completed in 1233), which has led some scholars to argue that it was actually a madrasa. These scholars have commonly identified it as most likely being the Madrasa al-Sharabiya, a school for Islamic theology built in 1230 by Sharif al-Din Iqbal, while some have identified it as the Bishiriya Madrasa, built in 1255. Another scholar, Yasser Tabbaa, has argued that the building lacks some key features of a madrasa and therefore its identification as a palace remains more plausible. He notes that some historical sources mention the construction of the ''Dar al‐Masnat'' ("House by the Breakwater") begun by al-Nasir around this location towards 1184, which could therefore correspond to this structure. Significant parts of the building were reconstructed in the 20th century by the State Establishment of Antiquities and Heritage, including restoration of the great iwan and the adjacent facades.

Mosques

The Abbasid continued to follow the Umayyad rectangular hypostyle plan with arcaded courtyard and covered prayer hall. They built mosques on a monumental scale using brick construction, stucco ornament and architectural forms developed in Mesopotamia and other regions to the east. The earliest mosque was built by al-Mansur in Baghdad, since destroyed. The Great Mosque of Samarra (848–852) built by al-Mutawakkil had a rectangular floor plan measuring . It had a flat wooden roof was supported by columns and was decorated with marble panels and glass mosaics. The Abu Dulaf Mosque (859–861) near Samarra also had a rectangular floor plan, an open-air sahn, and a prayer hall with arcades on rectangular brick piers running at right angles to the qibla wall.

Other surviving Abbasid mosques are the Mosque of Ibn Tulun in Cairo (877–879), the Tarikhaneh (or Tārī Khāna) in Damghan, Iran (750–789), the Nuh Gunbad (Nine Dome) Mosque in Balkh, Afghanistan (9th century). These mosques all had hypostyle forms with internal courtyards. The Ibn Tulun Mosque is one of the best-preserved Abbasid mosques anywhere and one of the most impressive provincial mosques of this era. Its design is a product of the Samarra style being adapted by local craftsmanship, probably on the instructions of its patron, Ahmad Ibn Tulun, who had spent time in Samarra. It has a nearly square floor plan with a vast interior courtyard surrounded by roofed spaces with rectangular piers and pointed arches. The design of its arcades, in which carved decoration and solid surfaces alternate with the main arches and smaller arched openings in the spandrels, forms an visual rhythmic effect that further exploits the potential of basic Abbasid design. The Tarikhaneh mosque in Damghan, whose structure dates from the 9th century or the second half of the 8th century, is the only early Abbasid mosque in Iran to preserve much of its original form. However, the 10th-century the Friday Mosque of Nā'īn (also spelled Nain or Nayin) preserves some of the best Abbasid stucco decoration of its time, covering its pillars, arches, and ''mihrab''. The Great Mosque of Isfahan was also first built during the Abbasid period, but little remains of this construction as it was rebuilt and expanded in later centuries. The mosque at Balkh was about square, with three rows of three square bays, supporting nine vaulted domes. Other nine-domed mosques have been found in Spain, Tunisia, Egypt and Central Asia.

The first known minarets built as towers appeared under Abbasid rule. Four towers were added to the Great Mosque of Mecca during its Abbasid reconstruction in the late 8th century. In the 9th century single minaret towers were built in or near the middle of the wall opposite the qibla wall of mosques. These towers were built across the empire in a height to width ratio of around 3:1. One of the oldest minarets still standing is that of the Great Mosque of Kairouan in Tunisia, built in 836 under Aghlabid rule and still well-preserved today. Other minarets that date from the same period, but less precisely dated, include the minaret of the Friday Mosque of Siraf, now the oldest minaret in Iran, and the minaret opposite the qibla wall at the Great Mosque of Damascus (known as the "Minaret of the Bride"), now the oldest minaret in the region of Syria (though its upper section was probably rebuilt multiple times). In Samarra, the Great Mosque of Samarra featured a massive helicoidal or "spiral" minaret behind its northern wall, known as the Malwiya. This unique design was repeated once more in the minaret of the nearby Abu Dulaf Mosque, but no other examples were built elsewhere. A possible exception is the minaret of the Mosque of Ibn Tulun, which has a spiral staircase that seems to imitate the minarets of Samarra (though the current structure was at least partly reconstructed in the late 13th century). Some early scholarly theories proposed that these helicoidal minarets were inspired by ancient Mesopotamian ziggurats, but this view has been challenged or rejected by some later scholars including Richard Ettinghausen, Oleg Grabar, and Jonathan Bloom.

Other buildings

Houses were often built in blocks. Most houses seem to have been two story. The lower level was often sunken into the ground for coolness, and had vaulted ceilings. The upper level had a timber ceiling and a flat terraced roof that provided living space in summer nights. Houses were built around courtyards, and had featureless exteriors, although they were often elaborately decorated inside. There are no traces of windcatchers, which later became common Islamic architectural features. Most of the houses had latrines and facilities for cold-water bathing.

The oldest surviving example of a domed tomb in Islamic architecture is the ''Qubbat al-Sulaibiyya'' in Samarra, present-day Iraq, dating from the mid-9th century (c. 862). It consists of an octagonal structure with a central square chamber covered by a dome. According to Ernst Herzfielf, who first documented the building in modern times, it was the mausoleum of Caliph al-Muntasir (d. 862), after which the caliphs al-Mu'tazz (d. 869) and al-Muhtadi (d. 870) were also buried here. The construction of domed tombs became more common among both Shi'as and Sunnis during the tenth century, although early Sunni mausoleums were mostly built for political rulers, whereas the Shi'as built them especially over the tombs of the Prophet Muhammad's descendants. Another important example of the latter is the Samanid Mausoleum in Bukhara, present-day Uzbekistan, built in the tenth century by the Samanids (one of the dynasties that ruled under Abbasid suzerainty). In the early 10th century the Abbasids also built another grand mausoleum for their dynasty on the east bank of the Tigris River in Baghdad, but it was later destroyed.

Some late Abbasid monuments have been preserved in Baghdad, including Mausoleum of Sitta Zubayda (or Zumurrud Khatun), built around 1152 or before 1202, the al-Wastani (or al-Jafariya) Gate, built in 1221, and the Mustansiriya Madrasa, built in 1228–1233. All have been significantly modified or restored in recent times. The Mausoleum of Sitta Zubayda, probably built by Caliph al-Nasir for his mother, exemplifies an original type of mausoleum that was being built in Mesopotamia around this period: a polygonal chamber is covered by a cone-like ''muqarnas'' dome. The Mustansiriya Madrasa was the first documented madrasa that was built to teach all four Sunni ''madhhabs''. It followed the four-iwan plan common in contemporary Iranian architecture, but it had an unusually elongated form, possibly imposed by the narrow urban site. The courtyard displays a sophisticated combination of vaulting and carved relief decoration. It has two major iwans aligned with its long axis and a two triple-iwan façades aligned with its short axis.

The Abbasids also undertook public works that included construction of canals in Samarra and of cisterns in Tunisia and Palestine. The Nilometer at Fustat, near modern Cairo, built in 861, has elaborate and ornate stonework and discharging arches.

Decoration

The three types (Styles A, B, and C) of stucco decoration best exemplified, and perhaps developed, in Abbasid Samarra were quickly imitated elsewhere and Style C, which itself remained common in the Islamic world for centuries, was an important precursor to fully developed arabesque decoration. The Tulinids in Egypt built copies of Abbasid buildings on Cairo. The Ibn Tulun Mosque, built in Fustat near Cairo in 876-879, combines Umayyad and Abbasid structural and decorative features. It is the only mosque outside Iraq to have a spiral minaret.
