The Abbasid Dynasty: A New Era of Islamic Rule
In the year 750 CE, a new dynasty emerged in the Islamic empire, known as the Abbasids. They were able to overthrow the ruling Umayyad Dynasty and assume the title of caliph, making them the second dynasty to hold this position in Islamic history. The Abbasids were able to rule over most of the empire, with the exception of some western regions, and held spiritual supremacy as caliphs until 1258 CE.
The rise of the Abbasids marked a significant shift in Islamic history. They raised the slogan of giving the ‘Ahl al-Bayt’ (the household of the Prophet) their due right – the caliphal throne. The Umayyads, who preceded the Abbasids, were known for their efficient administration and military might. However, they failed to contain the alienation of various Arab and non-Arab factions, particularly the Shias and Persians. Additionally, by the end of their reign, the inner circle of the ruling family had a falling out, and their grip on the empire loosened. This led to the open rebellion and the eventual downfall of the last Umayyad ruler, Marwan II.
Prelude
The Abbasids were able to capitalize on this opportunity and were able to establish their rule through a potent mixture of politics and military force. However, by the time of the Crusades (1195-1291 CE), their empire had fragmented and they were a mere shadow of their former past. In 1258 CE, their rule came to an end after the Mongols destroyed Baghdad. A series of “shadow caliphs” continued under the suzerainty of the Mamluk Sultanate of Egypt (1250-1517 CE). In 1517 CE, with the conquest of the Mamluk Sultanate by Sultan Selim I of the Ottoman Sultanate (1299-1924 CE), the title was officially transferred to the Turks, although they had been claiming it long before that time. With the Abbasids died the era of Arab supremacy over Islam.
Overall, the Abbasid Dynasty was a significant period in Islamic history, marked by a shift towards politics and military force as a means of maintaining power. Although their rule eventually came to an end, their legacy lives on as a crucial era in the development of the Islamic empire.
The Crusades
As the youngest uncle of the Prophet Muhammad, Abbas ibn Abd al-Muttalib had a special place in the hearts of many Muslims. His descendants, the Abbasids, sought to claim their rightful place as leaders of the Islamic empire, raising the slogan of giving the ‘Ahl al-Bayt’ their due right – the caliphal throne. Though the true meaning of ‘Ahl al-Bayt’ was left ambiguous, it was believed that the Abbasids were referring to themselves as the rightful heirs.
Led by the mysterious figure of Abu Muslim, the underground movement gained momentum and by 750 CE, the Abbasid revolution was reaching its climax. In a desperate attempt to hold onto power, the Umayyad caliph, Marwan, ordered the capture of the leader of the Abbasid clan, Ibrahim, who was brutally killed. His younger brother, Abu Abbas as-Saffah, then assumed the charge of the movement and swore to take the severest of all retributions.
The bulk of the Abbasid forces met with Marwan’s army near the Greater Zab river and emerged victorious as the Umayyad army fled in panic. Marwan, who had escaped to Egypt, was eventually found and killed. Abu Abbas as-Saffah, known as “the bloodthirsty,” was declared caliph in Kufa.
The Shias, who had supported the Abbasids in the belief that they were fighting for the descendants of Ali, soon realized that their emotions had been used for the benefit of the Abbasids. In the aftermath of their victory, as-Saffah immediately led his army to Central Asia to halt the expansion of the Chinese Tang Dynasty, where they were able to inflict a decisive defeat at the battles of Talas.
With the dawn of the Abbasid rule, the Islamic empire entered into a new era. Instead of expansion, the Abbasids chose to focus on aggrandizing and securing what they already possessed. A new capital was commissioned by Al-Mansur, the city of Baghdad, which would become one of the most bustling metropolises of the time, surpassing even European cities in grandeur.
However, the rule of the Abbasids was not without its atrocities, as the wrath of the house of Abbas was unleashed upon the descendants of their own family, committing severe atrocities, sparing neither the living nor the dead. The Umayyads graves in Syria were dug out, their remains were torn and burnt, and the living male members were all massacred. Those who went into hiding were lured out with promises of safety and reconciliation, only to be treacherously murdered. Only a young lad named Abd al-Rahman I managed to escape and fled to Spain, where he founded the Emirate of Cordoba in 756 CE.
Thus, the legacy of Abbas ibn Abd al-Muttalib and the rise of the Abbasid dynasty was a complex and emotionally charged event in the history of Islam, marked by both triumphs and atrocities.
The rise of the Abbasid dynasty was a bloody and tumultuous time in history. The new caliphs, claiming to represent the “Ahl al-Bayt” (the family of the Prophet Muhammad), led a revolution against the Umayyad dynasty, using the support of the Shia Muslims who were eager to see the descendants of Ali take the throne.
Abu Muslim, a mysterious figure, played a key role in the overthrow of the Umayyads and the establishment of the Abbasid dynasty. However, once in power, the new caliphs, led by as-Saffah and al-Mansur, engaged in brutal acts of vengeance against the Umayyads, including the massacre of their male members and the desecration of their graves.
Despite their cruel actions, the Abbasids were able to establish a strong and prosperous empire, creating a new capital at Baghdad and successfully defending against Byzantine incursions. However, the legacy of their cruelty towards their opponents and the Alids (descendants of Ali) would continue to haunt the dynasty.

Al-Mahdi, who succeeded al-Mansur, was a more compassionate ruler, taking steps to make amends for the atrocities committed by his father. He was known for his generosity towards his people and his love for his queen, Al-Khayzuran.
Overall, the Abbasid dynasty played a significant role in shaping Islamic history, but their rise to power was marked by great cruelty and violence.
