Siege of Thessalonica Ends
Slavic warriors retreat from stubborn walls
After a prolonged siege, the Sclaveni, early Slavic tribes who had been raiding across the Balkans, finally gave up their assault on the Byzantine city of Thessalonica. Unable to penetrate the city's formidable defenses, they withdrew, leaving the second city of the Byzantine Empire intact. Thessalonica's survival ensured continued Greek cultural dominance in the region for centuries.
