Siege of Philippopolis (250)

The Goths were led by King Cniva who had crossed the Danube in 249 or 250 with two armies. His army attacked Novae and Nicopolis ad Istrum unsuccessfully before defeating the army of Emperor Decius at Augusta Traiana and moving on to Philippopolis.

Decius had been on his way to relieve Philippopolis with a reinforced army, but arrived too late.

After a long siege, Cniva was victorious after the city was betrayed by a citizen. The king subsequently allied himself with the governor of Thrace, Titus Julius Priscus, to take on the Roman Emperor Decius again at Abritus.
