The Fatimid Caliphate was an Ismaili Shia caliphate extant from the tenth to the twelfth centuries AD. Spanning a large area of North Africa, it ranged from the Atlantic Ocean in the west to the Red Sea in the east. The Fatimids, a dynasty of Arab origin, trace their ancestry to Muhammad's daughter Fatima and her husband ‘Ali b. Abi Talib, the first Shi‘ite imam. The Fatimids were acknowledged as the rightful imams by different Isma‘ili communities, but also in many other Muslim lands, including Persia and the adjacent regions. Originating during the Abbasid Caliphate, the Fatimids conquered Tunisia and established the city of "al-Mahdiyya". The Ismaili dynasty ruled territories across the Mediterranean coast of Africa and ultimately made Egypt the center of the caliphate. At its height, the caliphate included – in addition to Egypt – varying areas of the Maghreb, Sudan, Sicily, the Levant, and the Hijaz.
The Fatimid dynasty was an Isma'ili Shi'a dynasty that ruled an extensive empire, the Fatimid Caliphate, between 909 and 1171 CE. Claiming descent from Fatima and Ali, they also held the Isma'ili imamate, claiming to be the rightful leaders of the Muslim community. The line of Nizari Isma'ili imams, represented today by the Aga Khans, claims descent from a branch of the Fatimids.
Abū Muḥammad ʿAbd Allāh/ʿUbayd Allāh ibn al-Ḥusayn, 873 – 4 March 934, better known by his regnal name al-Mahdi Billah, was the founder of the Isma'ili Fatimid Caliphate, the only major Shi'a caliphate in Islamic history, and the eleventh Imam of the Isma'ili faith.
Abū Ibrāhīm Ismā'īl ibn-i Aḥmad-i Sāmāni, better known simply as Ismail-i Samani, and also known as Isma'il ibn-i Ahmad, was the Samanid amir of Transoxiana (892–907) and Khorasan (900–907). His reign saw the emergence of the Samanids as a powerful force. He was the son of Ahmad ibn-i Asad and a descendant of Saman Khuda, the eponymous ancestor of the Samanid dynasty who renounced Zoroastrianism and embraced Islam.
Abū'l-Ḥasan Mu'nis al-Qushuri, also commonly known by the surnames al-Muẓaffar and al-Khadim, was the commander-in-chief of the Abbasid army from 908 to his death in 933 CE, and virtual dictator and king-maker of the Caliphate from 928 on.
Simjur al-Dawati was a 10th-century Turkic general who served the Samanids. He was the founder of the Simjurid family which would play an important role in the Samanid Empire.
The first Fatimid invasion of Egypt occurred in 914–915, soon after the establishment of the Fatimid Caliphate in Ifriqiya in 909. The Fatimids launched an expedition east, against the Abbasid Caliphate, under the Berber general Habasa ibn Yusuf. Habasa succeeded in subduing the cities on the Libyan coast between Ifriqiya and Egypt, and captured Alexandria. The Fatimid heir-apparent, al-Qa'im bi-Amr Allah, then arrived to take over the campaign. Attempts to conquer the Egyptian capital, Fustat, were beaten back by the Abbasid troops in the province. A risky affair even at the outset, the arrival of Abbasid reinforcements from Syria and Iraq under Mu'nis al-Muzaffar doomed the invasion to failure, and al-Qa'im and the remnants of his army abandoned Alexandria and returned to Ifriqiya in May 915. The failure did not prevent the Fatimids from launching another unsuccessful attempt to capture Egypt four years later. It was not until 969 that the Fatimids conquered Egypt and made it the centre of their empire.
The second Fatimid invasion of Egypt occurred in 919–921, following the failure of the first attempt in 914–915. The expedition was again commanded by the Fatimid Caliphate's heir-apparent, al-Qa'im bi-Amr Allah. As during the previous attempt, the Fatimids captured Alexandria with ease. However, while the Abbasid garrison in Fustat was weaker and mutinous due to lack of pay, al-Qa'im did not exploit it for an immediate attack on the city, such as the one that had failed in 914. Instead, in March 920 the Fatimid navy was destroyed by the Abbasid fleet under Thamal al-Dulafi, and Abbasid reinforcements under Mu'nis al-Muzaffar arrived at Fustat. Nevertheless, in the summer of 920 al-Qa'im was able to capture the Fayyum Oasis, and in the spring of 921 extend his control over much of Upper Egypt as well, while Mu'nis avoided an open confrontation and remained at Fustat. During that time, both sides were engaged in a diplomatic and propaganda battle, with the Fatimids' in particular trying to sway the Muslim populace on their side, without success. The Fatimid expedition was condemned to failure when Thamal's fleet took Alexandria in May/June 921; when the Abbasid forces moved on Fayyum, al-Qa'im was forced to abandon it and flee west over the desert.
