The Rubicone is a river located in northeast Italy, extending approximately 80 kilometers. It was famously known as the river that Julius Caesar crossed in 49 B.C., initiating the Roman Civil War. The phrase "crossing the Rubicon" now represents a point of no return, stemming from this historical event. The river originates from the Apennine Mountains and flows into the Adriatic Sea. The exact location of the historical Rubicon is a topic of debate among historians as changes in the river's course and Roman control over the centuries have impacted its precise identification.
