Overview
The road to the caliphate
Al-Tabari says that in 279 AH Ja'far al-Mufawwid was deposed from the heirship and al-Mu'tadid took it in Muharram. 1 2
Al-Mas'udi relates that he was Abu al-Abbas Ahmad ibn Talha al-Muwaffaq, and that his mother was a Byzantine concubine called Darar. He was given the allegiance on the day his uncle al-Mu'tamid died, on Tuesday, twelve nights before the end of Rajab 279 AH. 7
His wars
Al-Tabari says that he went against the Banu Shayban in 280 AH, and a battle took place between him and the Kurds and the Arabs in 281 AH. 3 4
Al-Suyuti says that after the death of Ibn Tulun in 270 AH al-Muwaffaq appointed him over Ibn Tulun's lands and equipped him for Egypt, where a great battle took place between him and Khumarawayh, and the victory went to the Egyptians. 5
Al-Mas'udi says that he camped at Amid in 286 AH and besieged it until its lord Muhammad ibn Ahmad came down on terms of safe conduct. 8
His image among the historians
Al-Suyuti says that he was born in Dhu al-Qa'da 242 AH, and was a brave and awe-inspiring king. He was called "the second al-Saffah", because he renewed the rule of the Banu Abbas after weakness. He abolished the dues and spread justice, and disturbances subsided in his days because of his great awe. 6
Al-Suyuti relates that he ordered a book burned in which were collected the indulgences of the scholars' slips, when he was told that whoever took up every slip of the scholars would lose his religion. 6
Al-Mas'udi says that disturbances subsided in his caliphate, the lands were put in order, and every opponent kept the peace with him, and that he defeated Harun al-Shari. He is also said to have been niggardly, and he left in the treasuries nine thousand thousand dinars and forty thousand thousand dirhams. 7
Al-Mas'udi also relates the report of the delegation of the people of Basra who complained to him of drought and the injustice of the governors, and that he answered what they asked. 8
He relates a report of his pursuit of a thief who had broken into the house of the treasurer of the soldiers' stipends, until he brought the money out of him after torture. 9
He also relates, with the family of Abu Talib, that money came from Muhammad ibn Zayd in Tabaristan to be distributed secretly among the Talibids. He disapproved of the man's concealing it, ordered him to make it public, and brought the Talibids close because of their kinship with him. 11
His death
He died on Sunday, seven nights before the end of Rabi al-Akhir 289 AH. Al-Mas'udi says his caliphate lasted nine years, nine months and two days. 7
