Under the Laskaris and Palaiologos dynasties, 1246–1423
Andronikos Palaiologos was the last Byzantine governor of the city. In 1423, Emperor John VIII Palaiologos, Andronikos's brother, ceded the city to the Republic of Venice to prevent it from falling to the Ottoman Empire, which was besieging it at the time.
