Despite the festive atmosphere, there were continued problems in the provinces. In late 248, the legions of Pannonia and Moesia, dissatisfied with the result of the war against the Carpi, rebelled and proclaimed Tiberius Claudius Pacatianus emperor. The confusion that this entailed tempted the Quadi and other Germanic tribes to cross the frontier and raid Pannonia. At the same time, the Goths invaded Moesia and Thrace across the Danube frontier, and laid siege to Marcianopolis, as the Carpi, encouraged by the Gothic incursions, renewed their assaults in Dacia and Moesia. Meanwhile, in the East, Marcus Jotapianus led another uprising in response to the oppressive rule of Priscus and the excessive taxation of the Eastern provinces. Two other usurpers, Marcus Silbannacus and Sponsianus, are reported to have started rebellions without much success.
