Key Takeaways

  • Strategic patience over revenge: Constantius delays pursuing defeated rival Magnentius for one full year to secure the Danube frontier against Sarmatians, prioritizing external threats over internal enemies despite personal desire for retribution against his brother's killer.
  • Cost of civil war: Battle of Mursa Major kills 55,000 trained Roman soldiers in one day—30,000 from Constantius's 60,000-man army and 25,000 from Magnentius's 35,000—critically weakening empire defenses during period of constant external attacks from multiple frontiers.
  • Political manipulation through paranoia: Court advisors exploit Constantius's natural suspicion by forging letters to frame loyal general Silvanus for treason, causing him to actually revolt in self-defense before being executed—demonstrating how manufactured conspiracies become self-fulfilling prophecies.
  • Family succession dilemma: After executing inexperienced Caesar Gallus for misrule after only three-and-a-half years, Constantius faces identical problem—needing imperial colleague for eastern provinces but having only bookish, untested cousin Julian remaining as family option.

That's rubrik.com. Hello, and welcome to the history of Rome. Episode one forty two, you've earned it. Last time, we left off with Constantius the second, finally headed west after extracting himself from the war with Persia in the winter of three fifty AD. It had been almost a year since the Gallic general, Magnentius, had overthrown and killed Constantius' younger brother Constance, and it was finally, finally time for the emperor to do something about it. While on his way to Dole out some imperial retribution though, Constantius had to stop along the way to take care of some business. You'll recall from last week that in March '50 at the prompting of Constantina, the general Vatranio had declared himself Augustus at his headquarters along the Danube frontier. He had made this move specifically to aid Constantius, and to counter the rise of magnetius. But when push came to shove, who knew what his ultimate ambitions were? Or what Constantius's reaction was going to be to Vitranio's self elevation. So far, the emperor had let it slide because he had been tied up with the war against the Sassanids, but now, who knows? As Constantius approached the Dacian city of Sardica though, it became obvious that neither man was planning to double cross the other. The aging Petronio welcomed 33 year old Constantius as the true Augustus, and Constantius accepted the welcome without malice. They then traveled together across the province to Nisys, where on December 25, the two leaders mounted a stage before an assembly of troops. The soldiers had been instructed to reaffirm their allegiance to Constantius, and so right on cue, they reaffirmed their allegiance to Constantius. The emperor accepted their pledge of loyalty, and then thanked Petronio for the good work he had done defending his family's honor. Then he graciously accepted the general's resignation, not just from the office of Augustus, but from the army completely. There were no hard feelings on either side, but there was absolutely no way Constantius could afford to have a man who had sniffed imperial power remain anywhere near that power. It was just bad for business. Vatranio was allowed to live out the rest of his days as a private citizen supported by a generous state pension. Constantius then traveled north to Sirmium where he took stock of the situation on the Danube frontier and made his arrangements for the coming war with Magnentius. Aware that battle would likely be joined in the spring, Constantius called his cousin Gallus to court in March '51, and formally elevated him to the rank of Caesar for all of the reasons I …
