Al-Mu'izz li-Din Allah succeeded his father al-Mansur and began a reign that would culminate in the Fatimid shift of power from Ifriqiya (North Africa) to Egypt.
Al-Mu'izz dispatched his general Jawhar westward to reassert Fatimid authority in the Maghrib; the expedition reduced major centers and advanced as far as the Atlantic, consolidating Fatimid control before the Egypt campaign.
The death of Abu al-Misk Kafur—Ikhshidid Egypt’s de facto ruler—triggered a succession and factional crisis that weakened the regime on the eve of the Fatimid invasion.
Following the conquest, Jawhar established a new palace-city north of Fustat for the Fatimid court and army—initially named al-Mansuriyya and later known as al-Qahira (Cairo).
Fatimid forces under Jawhar launched the decisive invasion of Egypt against the Ikhshidid regime, opening the campaign that would bring Egypt under Fatimid rule.
Jawhar secured Egypt’s administrative center at Fustat, completing the conquest phase and enabling consolidation of Fatimid administration in the Nile valley.
Jawhar ordered construction of a congregational mosque for the new Fatimid capital; al-Azhar became a major institutional base for Fatimid Isma'ili religious life and teaching.
The Qarmatians of Bahrayn invaded as the Fatimids expanded from Egypt into the Levant; although the Fatimids held Egypt, the wider struggle constrained early Fatimid consolidation and ambitions in the region.
Al-Azhar was completed for use and hosted its first Friday prayers, marking a key milestone in establishing Fatimid ceremonial and religious presence in the new capital.
After preparations to transfer the dynasty’s treasury and court, al-Mu'izz left al-Mansuriyya in Ifriqiya, initiating the formal relocation of the Fatimid center of power to Egypt.
At Sardaniya, al-Mu'izz appointed Buluggin ibn Ziri to govern Ifriqiya on the Fatimids’ behalf—an administrative step that helped manage the Maghrib as the court relocated east.
Al-Mu'izz arrived in Egypt and took up rule from the new royal city (Cairo), completing the strategic transfer of the Fatimid caliphate’s political center from North Africa to Egypt.
A renewed Qarmatian offensive, aided by local opposition, pressured the early Cairo regime; the Fatimids ultimately defeated the invasion, stabilizing their hold over Egypt after the court’s move.
Al-Mu'izz died after consolidating Fatimid rule in Egypt and establishing Cairo as the caliphal capital; he was succeeded by his son al-Aziz Billah.
