Theodosius and Arbogost's War on the Roman Empire

Theodosius had just finished doing his penance for ordering the massacre at Thessalonica. Left behind to govern the Western provinces was 20-year-old Valentinian II. Arbogost led a campaign against Germanic tribes, and whipped them back into place pretty quick. This battlefield success led to Arb Bogost's growing sense of entitlement. He probably felt like he had earned the free hand he was now assuming he had.
