Byzantine Civil War of 1341: What Happened

From 1341 to 1347, the Byzantine Empire was torn apart by a devastating civil war. When the emperor Andronikos III died in 1341, his son John V was only nine years old. The late emperor's close friend and chief minister, John Kantakouzenos, expected to guide the government, but a rival faction, led by the Empress Anna of Savoy, the Patriarch John Kalekas and the powerful official Alexios Apokaukos, seized control of the regency. Kantakouzenos was declared an enemy and responded by proclaiming himself emperor. The conflict became a bitter social struggle, with the wealthy landowners largely supporting Kantakouzenos, while many ordinary townspeople backed the regency. Both sides invited foreign help. Kantakouzenos allied with the Ottoman ruler Orhan, who married his daughter, and brought Turkish troops into Europe, while Serbia and Bulgaria seized Byzantine territory. In 1347, Kantakouzenos entered Constantinople and ruled as co-emperor with John V. The war left the empire impoverished, its lands devastated and its neighbors stronger, and it opened the door for the Ottomans in Europe.
