Abū al-ʿAbbās Abd Allāh ibn Hārūn al-Maʾmūn, better known by his regnal name al-Ma'mun, 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 resumption of large-scale warfare with the Byzantine Empire.
Abū Isḥāq Muḥammad ibn Hārūn al-Rashīd, better known by his regnal name al-Muʿtaṣim biʾllāh, was the eighth Abbasid caliph, ruling from 833 until his death in 842. A younger son of Caliph Harun al-Rashid, he rose to prominence through his formation of a private army composed predominantly of Turkic slave-soldiers. This proved useful to his half-brother, Caliph al-Ma'mun, who employed al-Mu'tasim and his Turkish guard to counterbalance other powerful interest groups in the state, as well as employing them in campaigns against rebels and the Byzantine Empire. When al-Ma'mun died unexpectedly on campaign in August 833, al-Mu'tasim was thus well placed to succeed him, overriding the claims of al-Ma'mun's son al-Abbas.
The Zanj Rebellion was a major revolt against the Abbasid Caliphate, which took place from 869 until 883. Begun near the city of Basra in present-day southern Iraq and led by one Ali ibn Muhammad, the insurrection involved both enslaved and freed East Africans or Abyssinians exported in the Indian Ocean slave trade and transported to slavery in the Abbasid Caliphate in the Middle East, principally to drain the region's salt marshes. It grew to involve slaves and freemen, including both Eastern Africans and Arabs, from several regions of the Caliphate, and claimed tens of thousands of lives before it was fully defeated.
Wasit was an early Islamic city in Iraq. It was founded in the 8th century by the Umayyad viceroy of Iraq, al-Hajjaj ibn Yusuf, to serve as the region's seat and as the garrison of the Syrian troops who enforced Umayyad rule there. It was situated between the two traditional administrative centers and garrisons of Iraq, Kufa and Basra, hence its name Wasit. The city was abandoned centuries later and its ruins are located in the eponymous Wasit Governorate, southeast of Kut in southeastern Iraq.
Iraq and Pakistan established diplomatic relations in 1947. Cultural interaction and economic trade between Mesopotamia and the Indus Valley date back to 1800 BCE. In 1955, both Iraq and Pakistan joined the Baghdad Pact, a military alliance against the Soviet Union. However, when the king of Iraq was assassinated in 1958, Iraq pulled out of the Baghdad Pact, which was subsequently renamed to the Central Treaty Organization (CENTO). During the Ba'athist era, relations were at times cordial and sometimes hostile. However, following the 2003 invasion of Iraq that toppled the Ba'athist government, bilateral relations have stabilized; Pakistan has supported Iraq in its fight against the Islamic State and other militant groups active in the Iraqi conflict. Iraq maintains an embassy in Islamabad while Pakistan maintains an embassy in Baghdad.
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 of Ray, and then invaded Iraq and besieged Baghdad itself. The city fell after a year, al-Amin was executed, and al-Ma'mun became Caliph.

Sind was an administrative division of the Umayyad Caliphate and later of the Abbasid Caliphate in post-classical India, from around 711 CE with the Umayyad conquest of Sindh by the Arab military commander Muhammad ibn al-Qasim, to around 854 CE with the emergence of the independent dynasties of the Habbarid Emirate in Sindh proper and the Emirate of Multan in Punjab.

The Ushrusaniyya were a regiment in the regular army of the Abbasid Caliphate. Formed in the early ninth century A.D., the unit consisted of soldiers who were originally from the region of Ushrusana in Transoxiana.

A member of the Mus'abid family, he was related to the Tahirid governors of Khurasan, and was himself a prominent enforcer of caliphal policy during the reigns of al-Ma'mun, al-Mu'tasim, al-Wathiq, and al-Mutawakkil.
Abu 'Abdallah Ahmad ibn Abi Du'ad al-Iyadi was an Islamic religious judge (qadi) of the mid-ninth century. A proponent of Mu'tazilism, he was appointed as chief judge of the Abbasid Caliphate in 833, and became highly influential during the caliphates of al-Mu'tasim and al-Wathiq. During his tenure as chief judge he sought to maintain Mu'tazilism as the official ideology of the state, and he played a leading role in prosecuting the Inquisition (mihnah) to ensure compliance with Mu'tazilite doctrines among officials and scholars. In 848 Ibn Abi Du'ad suffered a stroke and transferred his position to his son Muhammad, but his family's influence declined during the caliphate of al-Mutawakkil, who gradually abandoned Mu'tazilism and put an end to the mihnah.

Zuṭṭ is an Arabicised form of Jat. Originally inhabitants of lower Indus Valley, Jats were present in Mesopotamia from the 5th century AD since the times of the Sasanian Empire, although their main migration occurred after the establishment of Umayyad Caliphate. They were one of the prominent ethnic groups in lower Iraq during the Islamic Golden Age, supplying mercenary soldiers to the Muslim states. Their mention fades from Arab chronicles after the 11th century.
The Capture of Basra was a significant event during the Zutt Rebellion, in which the Zutts seized control of the city and ruled it independently. The rebellion stemmed from their dominance over waterways and canals, allowing them to exert control over vital resources and trade routes in the region.
The Capture of Wasit occurred in 834 CE when the Zutt seized the strategic city of Wasit in Iraq during their rebellion against the Abbasid Caliphate. The Zutt, originally from the Indus Valley region, had established dominance over the marshlands between Wasit and Basra.
