Cause → Event → Consequence
Sparta launched an invasion into the Argolis, likely seeking to extend its influence or control over territory near its border. Hysiae, a stronghold southwest of Argos and east of Tegea, lay in contested borderland between the two rival city-states, making it a strategically significant point of confrontation during the ongoing Spartan–Argive conflicts of the period.
At Hysiae in the Argolis, around 669 BCE, Argive forces under the rule of the tyrant Pheidon defeated a Spartan army in one of the few major setbacks Sparta suffered against its neighbors. Pausanias records the battle as a significant Argive victory but provides no further details of the fighting; he noted only that he was shown the burial site of the Argive dead.
The defeat is thought by modern scholars to have been a turning point in military history, as it allegedly prompted the Spartans to abandon loose spear-throwing formations in favor of the disciplined hoplite phalanx. This tactical shift subsequently spread throughout the Greek world and became the dominant form of land warfare in the classical era.
