al-Mustansir bi'llah Ma'add ibn al-Zahir

Al-Mustansir billah Ma'add ibn al-Zahir, the eighth of the rulers of the Ubaydid state in al-Suyuti's phrasing, that is the Fatimid state. ²

He was installed in 428 AH at the age of seven, and remained in the caliphate sixty years and four months. Al-Dhahabi, as al-Suyuti quotes him, says he knew of no one in Islam, caliph or sultan, who remained that long. ²

In his days there was famine in Egypt, the like of which had not been known since the time of Joseph. It lasted seven years, until people ate one another. ²

He was prayed for in the Mansur mosque in Baghdad in 450 AH, when al-Basasiri took it with his money. ²
