Which polis in the Peloponnesus became known for its highly militaristic society after wars with Messenia?

Sparta is known for its highly militaristic society, particularly after its conflicts with Messenia, which significantly shaped its culture and social structure. The wars with Messenia resulted in Sparta gaining control over a large territory and establishing a system that heavily emphasized military training and discipline. This environment fostered the development of a society where citizenship and full rights were closely tied to military service. Spartan education, known as the agoge, was focused on producing skilled soldiers and instilling values of loyalty, endurance, and discipline, making Spartans some of the fiercest warriors in ancient Greece. The significance of warfare in Spartan life was so profound that they maintained a strict societal hierarchy, with helots (subjugated Messenian people) working the land while the Spartans trained for battle. Thus, the legacy of military prowess and societal organization in Sparta is well-documented and sets it apart from other city-states in the region.
