Argos remained neutral or the ineffective ally of Athens during the Archidamian War between Sparta and Athens. Argos' neutrality resulted in a rise of its prestige among other Greek cities, and Argos used this political capital to organize and lead an alliance against Sparta and Athens in 421 BC. This alliance included Mantinea, Corinth, Elis, Thebes, Argos, and eventually Athens. This alliance fell apart, however, after the allied loss at the Battle of Mantinea in 418 BC. This defeat, combined with the raiding of the Argolid by the Epidaurians, resulted in political instability and an eventual oligarchic coup in 417 BC. Although democracy was restored within a year, Argos was left permanently weakened by this coup. This weakening led to a loss of power, which in turn led to the shift of commercial focus from the Ancient Agora to the eastern side of the city, delimited by Danaou and Agiou Konstadinou streets.
