How did the death of Abu al-Misk Kafur affect the Fatimid conquest of Egypt?

The death of Abū al-Misk Kāfūr in 968 was a pivotal factor that enabled the Fāṭimid dynasty to successfully conquer Egypt.12

During his lifetime, Kāfūr—the de facto ruler of Egypt under the Ikhshīdids—maintained enough stability to deter Fāṭimid expansion. The Fāṭimid caliph al-Muʿizz had prepared for an invasion as early as 966, but he reportedly postponed the campaign out of respect for his mother’s pilgrimage to Mecca and the honorable treatment she received from Kāfūr while passing through Egyptian territory.123

Following Kāfūr’s death, the Ikhshīdid state fell into disarray, losing its ability to maintain order within its army and bureaucracy. The Fāṭimids immediately capitalized on this internal disorder, launching a successful invasion in 969 led by the general Jawhar, which resulted in the occupation of the country and the eventual establishment of Cairo as the new Fāṭimid capital.234
