  • 17 Boedromion: The cult of Asclepius is introduced at Athens. [1]
  • The young and popular Alcibiades is elected "Strategos" (one of a board of ten generals) and begins to dominate Athenian life and politics. A Quadruple Alliance of Athens, Argos, Mantineia and Elis, which has been organised by Alcibiades (in opposition to Nicias) confronts a Spartan-Boeotian alliance.
  • Around 420 BC, Spartans were excluded from participating in the Olympic Games due to their ongoing conflicts with other Greek city-states, violating a peace treaty. This exclusion was part of a broader effort to maintain the peaceful atmosphere of the games. [2]
