Start of the First Fatimid invasion of Egypt.

The First Fatimid invasion of Egypt took place in 914–915 CE, during the early expansion of the Fatimid Caliphate, an Isma?ili Shi?i state based in Ifriqiya (modern-day Tunisia). At this time, Egypt was under Abbasid control but was politically unstable and economically strained, making it an attractive target. The Fatimids, who claimed descent from the Prophet Muhammad through his daughter Fatima, viewed Egypt as strategically essential: it was wealthy, centrally located, and a gateway to the eastern Islamic world. Establishing control there would also strengthen their ideological challenge to the Sunni Abbasid caliphate in Baghdad.

The invasion was led by the Fatimid general Hubasa ibn Yusuf, later reinforced by the crown prince and future caliph al-Qa?im bi-Amr Allah. Fatimid forces advanced eastward along the Mediterranean coast and initially met with success, capturing key cities such as Sirte, Barqa (Cyrenaica), and Alexandria in late 914. Alexandria’s fall was particularly significant, as it provided the Fatimids with a major port and a foothold inside Egypt. However, their progress was slowed by logistical difficulties, resistance from local populations, and the challenge of operating far from their North African base.

The decisive struggle centered on the Nile Delta, where Abbasid authority was reorganized under the capable commander Takin al-Khazari. Rather than confronting the Fatimids immediately, Abbasid forces focused on defending Fustat, the administrative capital, and controlling Nile crossings. The seasonal flooding of the Nile worked against the invaders, disrupting supply lines and limiting movement. As Fatimid forces attempted to push south toward Fustat in 915, they were checked by coordinated Abbasid resistance and growing internal problems, including lack of provisions and declining morale.

By mid-915, the Fatimid invasion had clearly failed. Abbasid reinforcements arrived by land and sea, cutting off Fatimid positions in the Delta and forcing a retreat from Alexandria. The Fatimid army withdrew westward, suffering losses along the way, and Egypt remained under Abbasid control. Despite this setback, the invasion was significant because it demonstrated both Egypt’s vulnerability and the Fatimids’ determination to claim it. The lessons learned in this failed campaign directly informed later efforts, culminating in the successful Fatimid conquest of Egypt in 969 and the founding of Cairo as their new capital.
