Constantinople 717: The Siege That Saved Byzantium

In 717 AD, around 80,000 Umayyad soldiers marched on Constantinople, the heart of the Eastern Roman Empire. Behind its walls, fewer than 15,000 Byzantine defenders, led by Emperor Leo III, faced a siege that could have ended Byzantium. Commanded by Maslama ibn Abd al-Malik, the Umayyads attacked by land and sea. But Greek fire, winter, hunger, disease, and Bulgar attacks turned the siege into a disaster. For 13 months, Constantinople endured — and the Eastern Roman Empire survived.
