Danubian Wars (Fidem Pacis)

The Danubian Wars were a series of conflicts during the 17th century between the Roman Empire and its rebellious provinces in the northern Balkans. It coincided with several other conflicts elsewhere in the empire, including the Italian Wars and the Majmi wars of expansion, which diverted vital resources and ensured that the region was largely free of Roman control by the 1630s.

The Balkans, being close to the imperial heartland, was of far more concern to the government than other frontier areas. After the peace treaties recognising Italian independence, therefore, Romania redoubled its efforts in the Danube region, causing the conflict to drag on for decades more. However, it was never able to regain complete control of the countryside, and insurgencies and guerilla campaigns eventually forced it to grant much of the Balkans independence as well.
