Location
Cause → Event → Consequence
King Cniva crossed the Danube in 249 or 250 with two Gothic armies, raiding Roman territory in Thrace. After failing to take Novae and Nicopolis ad Istrum, he defeated Emperor Decius at Augusta Traiana, freeing his forces to march on the strategically important city of Philippopolis.
Cniva's Goths placed Philippopolis under siege. Emperor Decius advanced with a reinforced army to relieve the city but arrived too late. After a prolonged siege, the city fell when a citizen betrayed it to the Goths, resulting in a decisive Gothic capture of one of Thrace's major urban centers.
Following the fall of Philippopolis, the governor of Thrace, Titus Julius Priscus, defected and allied with Cniva against Emperor Decius. This combined Gothic and renegade Roman force subsequently confronted Decius at the Battle of Abritus, further destabilizing Roman authority in the Balkans.
