|Background story:||In 440, the Huns reappeared on the borders of the Roman Empire, attacking merchants at a market on the north bank of the Danube. Attila and Bleda threatened further war, claiming that the Romans had failed to fulfill their treaty obligations. They then crossed the Danube and laid waste to Illyrian cities and forts on the river. When the Romans discussed handing over the offending bishop, he slipped away secretly to the Huns and made his own peace with them, enabling them to take the city of Margus (modern Požarevac, Serbia).
Emperor Theodosius II had stripped the river's defenses in responding to earlier battles against the Vandals at Carthage in 440 and the Sassanids in Armenia in 441. This left Huns a clear path through Illyria into the Balkans, which they invaded in 441.
Attila the Hun captured Margus and Singidunum (Belgrade). Perhaps the worst Roman loss was the attack on the strategic city of Sirmium (modern Sremska Mitrovica) on the Sava. Sirmium was destroyed, with its citizens enslaved. A new invasion two years later took Attila to the walls of Constantinople.
