In page Gallipoli:

"

The Thracian Chersonese was part of the Eastern Roman Empire from its foundation in 395 AD. In 443 AD, Attila the Hun invaded the Gallipoli Peninsula during one of the last stages of his grand campaign that year. He captured both Callipolis and Sestus.[3] Aside from a brief period from 1204 to 1235, when it was controlled by the Republic of Venice, the Byzantine Empire ruled the territory until 1356. During the night between 1 and 2 March 1354, a strong earthquake destroyed the city of Gallipoli and its city walls, weakening its defenses.[citation needed]
