Caesar Crosses the Rubicon

Julius Caesar led his 13th Legion across the Rubicon River into Roman Italy, an act that was illegal under Roman law and constituted a declaration of war against the Senate. His words — 'the die is cast' — became one of history's most famous utterances.

Caesar's crossing triggered the Roman Civil War, ultimately leading to the collapse of the Roman Republic and the rise of the Roman Empire.
