Carpi Invasion and Breach of the Limes Transalutanus(245)
Background
Philip the Arab ceased subsidies to the Carpi — a sign of Roman financial pressure during the Third Century Crisis. The Carpi responded with force, exploiting the increasingly evident fragility of the Dacian Limes.
Campaign: Barbarian Incursions in Roman Dacia (170–271 AD)
Forces Engaged

The Battle
After Emperor Philip the Arab halted the annual subsidies paid to the Carpi, they launched a massive invasion into Dacia in 245 AD, completely overstretching the Limes Transalutanus. The Carpi plundered Dacia Malvensis and struck hard at Romula. Philip personally led a counter-offensive that repelled them by 247 AD, but permanently abandoned the Limes Transalutanus, withdrawing the frontier westward to the Olt river.
Casualties & Outcome
Roman Empire achieved victory over Carpi.
Limes Transalutanus permanently abandoned; frontier withdrawn to the Olt; Philip takes the title Carpicus Maximus; Dacia Malvensis devastated.
Significance & Legacy
The first major territorial concession in Roman Dacia. The permanent abandonment of the Limes Transalutanus foreshadowed the eventual evacuation of the entire province. Philip took the title Carpicus Maximus after the campaign.
