Four days later the chief functionaries and the ulema assembled in the palace, and Ahmed’s genealogy was established. Taj ud din the chief justice gave him the oath of allegiance, next the Sultan pledged his homage and faith in case the new Kalif acted always according to the Divine law of Islam, and all traditions of the Prophet, commanded what the law commands, forbade what the law forbids, and walked in the ways of the Almighty. Also that he received legally in the name of God the contributions of the faithful and gave them to those who had the right to receive them. The Kalif then invested Beibars with the sovereignty of countries submitted to Islam, and those which God might permit him to free from unbelievers. This act of investiture was fixed in a diploma, which was given to the Sultan. Then every man present pledged faith to the Kalif, now called Al Mostansir Billahi, and gave him homage. The Sultan sent an order to every prefect in the provinces to have the new Kalif recognized, his name mentioned in public prayers and stamped on new coinage. The Kalif gave the Sultan a mantle of the House of Abbas. Some days later this successor of Mohammed rode forth in public on a white steed with black trappings. He wore a black turban, a violet mantle, a collar of gold, and the sabre of a Beduin. On the day of installation the Kalif invested the Sultan with robes of office, and put a gold chain on his neck. After that the vizir read the diploma conferring sovereign power upon Beibars. The Sultan now mounted and rode through the city with great pomp and the utmost solemnity, preceded by the vizir and the grand marshal, who carried alternately above their heads the diploma given by the Kalif. All houses were decorated, and the Sultan’s horse walked on the richest of stuffs which had been spread on the streets of his passage. The following Friday the Kalif preached in the mosque of the citadel; the Sultan, uncertain of the effect which he might produce, and to be sure of results in every case, so arranged as to shower gold and silver coins from above on his person, and thus interrupt the discourse which he was giving. Beibars now formed for the Kalif a household with all the officers, horsemen and servants which were requisite. He added one hundred Mameluks, each having three dromedaries and three horses; he gave also two thousand mounted warriors, and a body of Beduins. The Sultan and the Kalif left Cairo for Damascus September 4th, 1262. On the 10th of October the Kalif took the road for Bagdad, attended by the generals Seïf ud din Bilban and Sonkor of Rūm who had been deputed to go with him to the Euphrates, and to hold themselves ready to follow into Irak at the first signal from the Kalif.
