Nikiasfrieden
The first stage of the war (known as the Archidamian War for the Spartan king, Archidamus II) lasted until 421 BC with the signing of the Peace of Nicias. The Athenian general Pericles recommended that his city fight a defensive war, avoiding battle against the superior land forces led by Sparta, and importing everything needful by maintaining its powerful navy. Athens would simply outlast Sparta, whose citizens feared to be out of their city for long lest the helots revolt.
