The Peloponnese War marks a change of course of the events in the history of Greece. While relying on its navy, Athens maintained the security of its essentially maritime lines of commerce and diplomacy. At the strategic level, when he made the political decision to undertake an expedition to Sicily, a secondary theater of operations, he set aside the precautions advised by Pericles, incurring one of his great mistakes in conducting the war. The Athenian strategy turned out to be more reactive to Spartan than proactive initiatives, particularly losing the opportunity to take advantage of the navigational maneuverability offered by its navy. In the simulation, at the strategic level, the following actions will be tested: protecting the maritime and land lines of communication between the regions of the Confederation of Delos (allies of Athens); As we develop our land power, we expand territorial conquests from the Allied regions since the beginning of the war (Acarnania and Thessaly) or from those invaded by our naval power.
