accompanied the representative of Uzbak Khan to deliver Uzbak's niece as a bride for al-Nasir Muhammad, cementing the Mamluk-Golden Horde alliance.
Despite subsequent prohibitions against the slave trade by Christian authorities (such as Clement V at the Council of Vienna in 1312), the Genoese returned to Caffa in 1313 with the permission of Uzbak Khan (Barker 162).
In the early 1320s, the Golden Horde and Persian Ilkhanate were at war, but Mamluk relations with Persia had considerably improved (a peace treaty was signed in 1323), and al-Nasir refused to aid Uzbak Khan in the conflict.
Given the periodic references to Genoa and Genoese merchants, Muslim sultans in Egypt, and Uzbak Khan of the Golden Horde (which Boccaccio identifies as Turkish) across the Decameron, there is no doubt he would have been aware of the broader political and commercial contexts outlined above.
Perhaps, likewise, Boccaccio heard reports about Segurano's death, which took place four or five years earlier, on the order of Uzbak Khan of the Golden Horde, the same "Osbech [.
