Byzantine Emperor Michael VIII Palaiologos sent letters to the Albanian leaders of Berat and Durrës in 1272 asking them to abandon their alliance with Charles I of Naples, leader of the Kingdom of Albania, who had captured and incorporated it at the same period in the Kingdom of Albania. However, they sent the letters to Charles as a sign of their loyalty. In 1274 Michael VIII recaptured Berat and after being joined by Albanians who supported the Byzantine Empire, marched unsuccessfully against the Angevin capital of Durrës. In 1280-1281 the Sicilian forces under Hugh the Red of Sully laid siege to Berat. In March 1281 a relief force from Constantinople under the command of Michael Tarchaneiotes was able to drive off the besieging Sicilian army.
Later in the 13th century Berat again fell under the control of the Byzantine Empire. In 1335 Albanians from Epirus Nova invaded the area of Berat and appeared in Epirus for the first time, while in 1345 the town passed to the Serbs. During the second half of the 14th century the noble Albanian family of Muzaka and became the capital of the Principality of Berat.
