In 1463, the Venetian Senate, seeking allies in its war against the Ottomans, sent Lazzaro Querini as its first ambassador to Tabriz, but he was unable to persuade Uzun Hassan to attack the Ottomans. Hassan sent his own envoys to Venice in return. In 1471, Querini returned to Venice with Hazzan's ambassador Murad. The Venetian Senate voted to send another to Persia, choosing Caterino Zeno after two other men declined. Zeno, whose wife was the niece of Uzun Hassan's wife, was able to persuade Hassan to attack the Turks. Hassan was successful at first, but there were no simultaneous attack by any of the western powers.
