Uzun Hassan
After yet another Venetian ambassador, Ambrogio Contarini, arrived in Persia, Uzun Hassan decided that Contarini would return to Venice with a report, while Giosafat Barbaro would stay. Barbaro was the last Venetian ambassador to leave Persia, after Uzun Hassan died in 1478. While Hassan's sons fought each other for the throne, Barbaro hired an Armenian guide and escaped.
