Bessarion's first contact with Venice had been in 1438 when, as the newly ordained metropolitan bishop of Nicaea, he arrived with the Byzantine delegation to the Council of Ferrara-Florence, the objective being to heal the schism between the Catholic and Orthodox churches and unite Christendom against the Ottoman Turks. His travels as envoy to Germany for Pope Pius II brought him briefly to the city again in 1460 and 1461. On 20 December 1461, during the second stayover, he was admitted into the Venetian aristocracy with a seat in the Great Council.
