The initial freestanding sculpture was developed by the Archaic Greeks, a recognized accomplishment since until then the sole carvings in existence were reliefs cut into walls and pillars. Kouros figures, sculptures of young, attractive male or female (kore) Greeks, made up the greater part of the statues. The kouroi, considered by the Greeks to exemplify beauty, had one foot extended out of a fixed forward-facing posture and the male statues were regularly nude, with a strong, powerful physique. In vendor pool 650 BC, life-size variations of the kouroi began to be observed. The Archaic period was an amazing point of transformation for the Greeks as they expanded into new modes of government, produced fresh expressions of art, and gained insights of the people and cultures outside of Greece. Equivalent to other moments of historical conflict, conflicts were commonplace, and there were struggles between city-states like The Arcadian wars, the Spartan invasion of Samos.
