49 BC   Julius Caesar leads his army across the Rubicon, which separates his jurisdiction (Cisalpine Gaul) from that of the Senate (Italy), and thus initiates a civil war. In response, the Roman senate invokes the ''senatus consultum ultimum''.

Suetonius also described how Caesar was apparently still undecided as he approached the river, and the author gave credit for the actual moment of crossing to a supernatural apparition. The phrase "crossing the Rubicon" has survived to refer to any people committing themselves irrevocably to a risky and revolutionary course of action – similar to the current phrase "passing the point of no returnPoint of no return

". It also refers, in limited usage, to its plainer meaning of using military power in a non-receptive homeland.

Location confusion

After Caesar’s crossing, the Rubicon was a geographical feature of note, but only for a few years, until Emperor Augustus abolished the Province of Gallia Cisalpina (today’s northern Italy), and the river ceased to be the extreme border line of Italy. Augustus’ decision caused the Rubicon to lose a great deal of importance, and as memories faded, the name “Rubicon” gradually disappeared from local toponymy.

 was flooded many times. The Rubicon, together with other small rivers of the region, often changed its course during this period. For this reason, and in order to supply fields with water after the revival of agriculture after the Middle Ages, during the 14th and 15th centuries hydraulic works were built to prevent other floods and to regulate streams. As a result of this, these rivers eventually turned into straight lines, which is how they appear today. As the centuries went by, several rivers of Italian Adriatic coast between Ravenna and Rimini have at times been said to correspond to the ancient Rubicon. The Via AemiliaVia Aemilia

In 1933, after various efforts spanning centuries, the river called Fiumicino, crossing the town of Savignano di Romagna (now Savignano sul RubiconeSavignano sul Rubicone
