Constantine Defeats Licinius at Cibalae: The Road to Sole Emperor
Constantine defeated his co-emperor Licinius at Cibalae in 314, killing 20,000 of his soldiers and seizing his European territories in a single afternoon. They'd been ruling the Roman Empire together for eight years under a power-sharing agreement that nobody believed would last. It didn't. The battle made Constantine master of two-thirds of the empire. Nine years later he'd finish the job, executing Licinius and becoming sole ruler. Shared thrones don't stay shared.
