Julius Caesar crosses the Rubicon, signalling the start of civil war.
In 49 BC, Julius Caesar crossed the Rubicon River, defying the Roman Senate and igniting a civil war that ultimately transformed the Roman Republic into an empire.
In 49 BC, Julius Caesar defied the Roman Senate and marched his legions across the Rubicon River, a boundary that commanders were forbidden to cross with troops. This bold action marked the start of a civil war against Pompey and the Senate's forces. Caesar's gamble paid off as he rapidly advanced into Italy, causing political allies to abandon Pompey. The ensuing conflict destabilized the Republic and ultimately led to Caesar's dictatorship. Historians view the Rubicon crossing as a decisive turning point that ushered in the end of the Roman Republic and set the stage for the Roman Empire.

He also maintained diplomatic channels with Emperor Maximinus I during a period of frequent persecution. Under his leadership, the Christian church continued to grow despite official hostility. Fabian's martyrdom under later Emperor Decius solidified his legacy as a steadfast early pope.
