In the spring of 1369 John V Palaiologos set sail from Constantinople with Demetrios Kydones and a large retinue. The destination was Italy; their immediate goal was to meet with Pope Urban V and his cardinals in Rome. The purpose of that extraordinary journey, however, and the subsequent meetings between Pope and Emperor in the fall of that year, was twofold: to assure Pope Urban V that the Byzantine Emperor was no longer a schismatic, and to persuade the Pope and his Curia to support a new military initiative that would aid the Byzantines in fending off the ever-increasing threat to the Empire from the Ottoman Turks.
