Editing Rubicon (section)

===Later history===
After Caesar's crossing, the Rubicon was a geographical feature of note until about 42 BC, when [[Augustus|Octavian]] merged the Province of [[Cisalpine Gaul]] into [[Italia (Roman Empire)|Italia]] and the river ceased to be the extreme northern border of Italy. The decision robbed the Rubicon of its importance, and the name gradually disappeared from the local toponymy.

After the [[fall of the Western Roman Empire]], and during the first centuries of the [[Middle Ages]], the coastal plain between [[Ravenna]] and [[Rimini]] was flooded many times. The Rubicon, like other small rivers of the region, often changed its course during this period. For this reason, and to supply fields with water after the revival of agriculture in the [[late 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 work, these rivers started to flow in straight courses, as they do today.
