A year later, a new sedition deposed the sultan, who had to flee and was replaced by his brother Izz al-Din Abd al-Aziz.

He even seemed to be a faithful servant by assisting the latter in suppressing the revolt of Djakam, emir of Aleppo, who proclaimed himself sultan.

However, An-Nasir Faraj recklessly arrested Al-Mu'ayyad who escaped and recaptured Damascus from Nauroz, his designated successor, to whom he ceded the governance of Tripoli.

Later on, Al-Mu'ayyad returned to Cairo and conspired to make the Abbasid caliph Abu’l-Faḍl Abbas Al-Musta'in Bi'llah unpopular, before he managed to dismiss him after seven months of reign and was proclaimed sultan.

[4] The situation that Al-Mu'ayyad found in Cairo was chaotic, the plague was wreaking havoc on the population, famine reigned and the currency was devalued.

The monetary situation was fixed, Bedouin incursions were repressed, and the agricultural production resumed with the price of cereals fell.

[5] Nauroz, emir of Damascus, refused to recognize Al-Mu'ayyad as new sultan, and proclaimed holy war under the pretext of the destitution of the caliph.

Al-Mu'ayyad responded by organizing a landing on the island, which prompted King Janus to sign a peace agreement, despite continuing Catalan pirates' raids on the coasts of Egypt and Syria.

[14] Al-Mu'ayyad was one of the major patrons of Mamluk architecture in his era, commissioning or restoring a number of buildings around Cairo.

[15] He also restored the hippodrome (training ground) near the Nile River which had been previously built by al-Nasir Muhammad and since abandoned.
