A sequence of scholarly lectures maps the political landscape of the Mediterranean world as then known, surveys legal and institutional developments, and recounts major military campaigns including anti‑piracy operations and wars in the East and West. The narrative traces the careers and actions of leading Roman figures, treats the Catiline conspiracy and Cicero’s consulship and exile, and follows Julius Caesar from his early rise through the Gallic wars and the civil conflict with Pompey to his Egyptian, African, and Spanish campaigns. Attention is given to resulting legislation, veteran settlements, and shifts in provincial and imperial administration.
