In the 8th century, a new dynasty emerged in the Middle East, taking control of the vast Islamic caliphate. This dynasty, known as the Abbasids, ruled for five centuries and presided over a period often called Islam’s Golden Age. During this time, the Islamic world saw remarkable achievements in military prowess, urban development, scholarship, and technological innovation.
The Abbasid caliphate reached its zenith under Caliph Harun al-Rashid. To ensure a smooth succession, he designated his son Muhammad as his heir and another son, Abdullah, as Muhammad’s successor. However, this arrangement led to conflict. In 809, Muhammad became caliph, taking the title al-Amin, while Abdullah, known as al-Ma’mun, governed from the eastern city of Merv. Tensions between the brothers escalated into a civil war, culminating in al-Ma’mun’s victory and al-Amin’s execution.
Al-Ma’mun initially ruled from Merv, forming an alliance with the Alids, descendants of Ali, the Prophet Muhammad’s son-in-law. This alliance, however, sparked unrest in Iraq, leading to revolts in Baghdad. Al-Ma’mun eventually moved the capital back to Baghdad and distanced himself from the Alids. He also attempted to impose a new religious doctrine, declaring the Quran as created rather than co-eternal with God, which led to the Mihna, a period of religious persecution.
Al-Ma’mun’s successor, al-Mu’tasim, focused on military matters, drawing soldiers from diverse regions, including Khorasan and Africa. The Abbasid army excelled in siege warfare, employing advanced weaponry like catapults and fire-based weapons. The rise of Turkish slave soldiers, known as Mamluks, marked a shift in military dynamics, leading to tensions with the traditional nobility. To manage these tensions, al-Mu’tasim established the city of Samarra for the Turkish elite.
Following al-Mu’tasim, the Abbasid caliphate faced internal strife and external challenges. The Decade of Anarchy saw a series of puppet caliphs controlled by the Turkish military elite. Regional uprisings further weakened Abbasid control, with Egypt and parts of Persia breaking away. The Zanj Rebellion in southern Iraq and the rise of independent dynasties like the Tulunids and Saffarids further eroded Abbasid power.
In the 10th century, the Seljuk Turks emerged as a formidable Sunni power, toppling the Buyids and establishing the Seljuk Empire. They revitalized Sunni Islam and expanded westward, capturing Baghdad and defeating Byzantine forces. Despite their military prowess, the Seljuks faced challenges from the Crusaders and the Assassins, a secretive Shia sect known for political assassinations.
The 13th century brought a new threat from the East: the Mongols. Led by Hulagu Khan, the Mongols advanced into the Islamic world, destroying cities that resisted. In 1258, they besieged Baghdad, leading to its catastrophic fall. The city was sacked, its libraries destroyed, and the last Abbasid caliph, al-Mustasim, was executed. This marked the end of Abbasid political power, although the dynasty continued in a ceremonial role under the Mamluks in Egypt.
Despite their decline, the Abbasids left a lasting legacy. They presided over a period of cultural and intellectual flourishing, influencing Islamic civilization for centuries. Their era is remembered as a time of great achievements in science, philosophy, and the arts. Even after their fall, Islamic leaders sought legitimacy by claiming descent from the Abbasids, underscoring the dynasty’s enduring influence.

In the 8th Century Middle East, a new dynasty seized control of one of the world’s greatest empires, the Islamic caliphate. Though little remembered in the West today, the Abbasids reigned for five centuries, overseeing an era of Islamic military dominance, city building, brilliant scholarship, and technological innovation. This period is often referred to as Islam’s Golden Age.
This is the story of the Abbasid caliphate.

The Abbasid caliphate flourished under the reign of Caliph Harun al-Rashid. To ensure its continued success, he arranged his succession in a way he believed would ensure stability and peace. His son Muhammad was to be his heir, but he also named another son, Abdullah, as Muhammad’s heir, which proved to be a recipe for disaster.
In 809 in Baghdad, Muhammad succeeded his father as caliph, taking the title al-Amin, “The Trustworthy.” His half-brother Abdullah became governor of the horizon with the title al-Ma’mun, “The Trusted One.” Rival factions soon formed at both courts. Al-Amin’s advisors urged him to remove his brother from the succession, and just a year into his reign, he tore up his father’s arrangement. Al-Ma’mun was furious, and fraternal distrust exploded into civil war.
Forces loyal to Al-Ma’mun won a great victory against a much larger force at Rey and marched to besiege Baghdad. After a bloody year-long siege, the city fell, and Caliph al-Amin was captured while trying to flee and was executed. Initially, al-Ma’mun ruled the caliphate from his old base at Merv, fostering a new alliance with the Alids, a powerful family descended from Ali, the fourth caliph and son-in-law of the Prophet Muhammad. They would later become leaders of Shia Islam, the branch of Islam that believes true spiritual authority belongs to Ali’s descendants.
Al-Ma’mun’s court began to wear green, a color associated with the Alids. He even married two of his daughters into the allied family and made Ali al-Rida his heir apparent. However, these policies sparked hostility back in Iraq and led to major revolts in Baghdad. After six years, the caliph moved the capital back to Baghdad to restore order and abandoned his alliance with the Alids.
Al-Ma’mun is also remembered for his attempts to impose a new religious doctrine on the caliphate. He invited distinguished scholars to Baghdad to discuss theological issues, but his pronouncements that the Quran was created by God rather than co-eternal with God encountered bitter resistance. This led to a period known as the Mihna or Inquisition, which saw dissenting scholars imprisoned or executed.
In 833, al-Ma’mun was succeeded by his brother, who took the title al-Mu’tasim. He proved far less interested in theological debate than in military matters. The armies of the Abbasid caliphate, renowned in battle, were drawn from both Arab and non-Arab subjects. Soldiers from the frontier province of Khorasan were instrumental in helping the Abbasids to power during the third Fitna or Islamic Civil War.
Drawing on Persian and steppe warrior traditions, their ranks included both armored infantry and heavy cavalry. The sons of Khorasan, known for their elite and versatile infantry, formed the loyal core of the caliph’s army. Other notable contingents included the Dalami, expert skirmishers from the highlands of Northern Persia, while African troops, including military slaves and Muslim converts from Ethiopia, fought as heavy infantry.
Abbasid armies were particularly skilled in siege warfare and made expert use of catapults, mangonels, and battering rams. They had specialist troops armed with naphtha or petroleum-based fire weapons. Historians have noted that at some point in the 9th century, these Turkish slave soldiers, known as Mamluks, formed an elite corps within the Abbasid army, personally loyal to the caliph.
Turkish officers began to wield significant influence at the caliph’s court, which offended the old nobility. Discontent even pushed some soldiers to riot in the streets of Baghdad. To ease tensions, al-Mu’tasim constructed a new city for the Turkish military elite, Samarra, where he garrisoned the Turks and rewarded their commanders with land.
Two years later, the caliph led his formidable new army against the Eastern Roman or Byzantine Empire, achieving a great victory with the capture and sack of Amorium. However, even such victories failed to ease tensions between Turkish officers and Abbasid nobles. Some nobles plotted to overthrow al-Mu’tasim and expel the Turks, but their conspiracy was discovered, and they were executed.
Al-Mu’tasim was succeeded by his eldest son, al-Wathiq. Following his unexpected death, a second son, al-Mutawakkil, took the throne, backed by the Turkish generals. However, al-Mutawakkil decided it was time to reassert caliphal authority. On his orders, several Turkish leaders were assassinated, and he attempted to use Arab and Armenian troops to counterbalance their influence. The Turks struck back, and in 861, the caliph was assassinated by his own bodyguards.
The chaos and civil war that followed is known as the Decade of Anarchy. Four caliphs took power, all puppets of the Turkish military elite, each in turn violently overthrown. Order was only restored with the accession of Caliph al-Mu’tamid in 870, but the anarchy had irreparably damaged the caliph’s authority.
Before the Abbasids came to power, the vast caliphate had struggled to maintain control of its many regions. Abbasid authority west of Egypt had long been largely theoretical, but now multiple major uprisings broke out as local governors and warlords staked their own claims to rule. Egypt, fertile and prosperous, was an early casualty, lost to a rebel Turkish commander who founded his own Tulunid dynasty.
In southern Iraq, a major revolt broke out among agricultural slaves from Eastern Africa known as the Zanj. This 14-year uprising devastated the region and severely disrupted Abbasid tax income and Baghdad’s food supply. In Afghanistan, a coppersmith named Yakub al-Saffar made an astonishing rise to power, founding his own Safarid dynasty and conquering much of Eastern Persia.
In such turbulent times, Abbasid caliphs struggled to impose their authority, but there were some successes. Caliph al-Mutadid engineered a brief Abbasid resurgence thanks to military campaigning and shrewd diplomacy, notably his marriage to the daughter of the Tulunid ruler of Egypt. She was celebrated for her intelligence and regal demeanor.
During the reign of al-Mutadid’s son, al-Muhtafi, Tulunid Egypt was fully reabsorbed into the Abbasid caliphate. However, elsewhere, the news was dire. Abbasid authority collapsed in Arabia, where one Shiite group, the Qarmatians, began attacking pilgrims on their way to holy Mecca. In 930, they stole the Black Stone from the Kaaba, a significant blow to Abbasid prestige.
In Central Asia, the Persian Samanids carved out their own empire and declared independence. This was the height of the so-called Persian Intermezzo, where native Persian dynasties ruled in Persia once more. Increasingly, the Abbasid caliph was said to reign but not rule, becoming a symbol without power, often under the thumb of his vizier.
By the 930s, the caliph had lost control of both the civilian administration and army command, which was handed over to a new official, the Amir al-Umara, or commander of the commanders. The final humiliation came in 945 when the Buyids, Shiite warlords from the mountains of Northwestern Persia, seized control of Persia and Iraq. Their triumphal entry into Baghdad was a deep humiliation for the Sunni Abbasids, yet they retained the title of caliph as mere figureheads.
Two decades later, another Shiite dynasty, the Fatimids, swept along the North African coast, conquered Egypt, and founded Cairo as the capital of their own caliphate. Some historians label this the Shiite century, with Shiite dynasties ruling twin caliphates and dominating much of the Muslim world.
However, it was not to last. A dangerous new Sunni power was poised to emerge from Central Asia: the Seljuk Turks. The Seljuk Turks were pastoralists and fierce warriors who became champions of Sunni Islam. At the end of the 10th Century, possibly in response to climate change, they surged south into Khorasan, toppling the Gaznavid Empire, a successor to the Samanids.
The Seljuk Turks were unstoppable, surging westwards across the Persian Plateau, taking Baghdad and toppling the Buyids, crushing a Byzantine army at Manzikert, and forging the great Seljuk Empire. Their triumph was tempered by the arrival of European Crusaders, who took Jerusalem in 1099 and carved out a series of Crusader states.
One Shia sect, shrouded in legend, struck back at the Seljuks with deadly precision. In 1092, Nizam al-Mulk, vizier of the Seljuk Empire, was killed by the order of the Assassins, a new Ismaili military order formed in the mountains of Northwestern Persia. Facing powerful enemies but lacking an army of their own, they turned to subterfuge and assassination to achieve their goals.
Many fanciful stories are told about the Assassins, but the order was real and feared, responsible for scores of political murders over the next two centuries. Under the Seljuks, Abbasid caliphs continued to reign as spiritual leaders and figureheads, but the 12th century saw the fracturing of the great Seljuk Empire, a familiar story of disputed successions and local governors making their bids for power.
Sensing weakness in 1136, Abbasid caliph al-Muhtafi raised his own army to reassert Abbasid independence for the first time in nearly two centuries. He took control of Baghdad and in 1157 held it against a Seljuk siege. After generations of foreign subjugation, the Abbasids had re-emerged as an independent power, but it would soon all come crashing down.
In the 13th century, a new force from the East tore through the Islamic world, scattering armies and destroying every city that did not submit to them: the Mongols. The Mongol Empire, successor to the Seljuks, was overrun by the Mongol hordes of Genghis Khan. By 1256, his grandson Hulagu was poised to renew the onslaught but first turned his attention to the Assassins, rumored to be plotting his death. The order was scattered and crushed.
Two years later, Hulagu advanced against the Abbasid caliphate. As his armies neared Baghdad, he sent a stern warning to Caliph al-Mustasim, demanding the city’s surrender. Despite the Mongols’ terrifying record of destroying any city that opposed them, al-Mustasim decided Baghdad’s walls could keep out any steppe nomads. He was wrong.
After half of Baghdad’s garrison was massacred in a disastrous sortie, the city surrendered, but Hulagu was in no mood for mercy. A contemporary chronicler described the horrors that followed: the people of Baghdad were put to the sword and subjected to 40 days of killing, pillaging, and enslavement. They tortured people to extort their wealth, killing men, women, and children. A great part of the city, including the caliph’s mosque, was burned, and the city lay in ruins. The death toll is unknown but was in the many thousands. Allegedly, only Christians were spared thanks to the intercession of Hulagu’s Christian wife.
Baghdad’s libraries were destroyed, their books and manuscripts representing centuries of Muslim scholarship thrown into the Tigris River, said to run black with ink. Al-Mustasim was forced to witness this terrible destruction, and according to several sources, he was rolled in a carpet and trampled to death, as Mongols feared to spill royal blood. The last caliph of Baghdad was dead, and never again would the Abbasids hold meaningful political power.
However, the line would continue under the Mamluks, who now ruled Egypt. But his successors in Cairo were merely ceremonial figures, religious leaders with little power. The last caliph, al-Mutawakkil III, surrendered to the Ottoman Empire in 1517 and was taken away as a prisoner to Constantinople.
It was a humiliating fate for a dynasty that had once ruled one of history’s greatest empires, one that had dominated the Middle East, taken on and defeated the Byzantines in the West and the Chinese in the East, overseen a great flourishing of scholarship, culture, technology, and trade, and reigned over the era that is remembered as Islam’s Golden Age. For centuries to come, Islamic leaders would assert their legitimacy by claiming descent from this one towering dynasty: the Abbasids.
