15 giug 987 anni - Traité entre les fatimides et les byzantins pour lire la Khutba de Constantinople au nom d'al‐ʿAziz

Descrizione:

A 987 treaty between Emperor Basil II and the Fatimid caliph al‐ʿAziz specified that the oath of allegiance (khutba) to the caliph, a key aspect of Friday prayers, be pronounced in the mosque of Constantinople in the name of the Fatimid caliph (Anderson 2009: 99–100). A century later, Empress Theodora broke the oath with the Fatimids by agreeing to have the khutba in the Constantinople mosque pro- nounced in the name of the Seljuq ruler Tughril Beg. At around the same time, the name of the Fatimid caliph al‐Hakim was read in the khutba in Abbasid realms, which were then under the control of the Buyids, another Shiʿi dynasty (Pruitt 2013: 129).
