This episode focuses on the opening of Caesar’s civil war, as the political tensions between Caesar and Pompey finally erupt after years of rivalry and mistrust. Students see how legal maneuvering in Rome gives way to decisive action when Caesar crosses the Rubicon, forcing Pompey and the Senate into panic and flight. The script emphasizes the speed at which Roman political norms collapse once civil war becomes inevitable, turning debate into armed conflict. For teachers, it offers a dramatic, story-driven way to introduce the breakdown of the Republic and the irreversible consequences of Caesar’s literal and metaphorical Rubicon.
