How did Badr al-Jamali restore order in Egypt in 1073?

In 1073, the Fatimid Caliph al-Mustanṣir invited the soldier Badr al-Jamālī to Cairo to address the anarchy and factional strife plaguing the region.1

Upon his arrival, Badr al-Jamālī seized power and immediately restored order by having his officers round up and execute the leading generals and officials responsible for the instability in a single night. Following this, he consolidated his authority by assuming the titles of commander of the armies, director of the missionaries, and vizier, which granted him total control over the military, religious, and bureaucratic establishments. This transition established a military regime that successfully stabilized the state and restored a measure of prosperity to Egypt.1
