The '''Rubicon River''' was a river in northern [[Italy]] in [[Roman]] times that was used as a boundry under Roman law. No leader was allowed to bring an army into Italy, which meant passing the Rubicon. As the flow of rivers change over time, modern scholars can only approximate where the river was located during the heyday of Ancient Rome.
