Classical Greece was organized around citizens, who were adult men born to citizen parents. They participated in politics through the Ecclesia and Heliaia courts and served in the military. Women, foreigners, slaves, and children were not considered citizens and lacked full political and legal rights. The economy was based on agriculture including crops, livestock, fishing, and trade, with Athens emerging as a powerful city-state after defeating Persia in the Greco-Persian Wars. Greek culture flourished during this Golden Age period in areas like literature, philosophy, mathematics, architecture and the arts. The landscape of Greece was mountainous and surrounded by seas, with many natural harbors contributing to its economic and cultural prominence.
