Michael VIII Palaiologos

Michael VIII Palaiologos's general Alexios Strategopoulos led a surprise attack that recaptured Constantinople from the Latin Empire without a major battle. The city was restored as the Byzantine capital, ending 57 years of Latin rule and re-establishing the Byzantine Empire.

Michael VIII was crowned emperor in Hagia Sophia in Constantinople, legitimizing his rule as the restorer of the Byzantine Empire. The coronation was a major symbolic event, reaffirming the continuity of the Roman imperial tradition in the East.

Michael VIII rebuilt the Byzantine navy, which had been neglected under the Nicaean emperors, and strengthened the fortifications of Constantinople. These measures improved the empire's defensive capabilities and allowed for limited naval campaigns in the Aegean.

Michael VIII agreed to the Union of the Churches at the Second Council of Lyon, recognizing papal supremacy in exchange for Western support against the Angevin threat. The union was deeply unpopular in Byzantium and caused religious strife, but it temporarily prevented a crusade against Constantinople.

Michael VIII's forces defeated an Angevin army besieging Berat in Albania, capturing the Angevin commander. The victory ended Charles of Anjou's plans to invade Constantinople and restored Byzantine control over parts of the Balkans.
