Answer:
Athens organized other Greek city-states into the Delian League.
Step-by-step explanation:
The Persian Wars occurred between the Greek and Persian peoples by the dispute over the Ionia in Asia Minor, when the Greek colonies of the region, mainly Miletus, tried to get rid of Persian rule. The conflict ended, leaving Greece victorious.
The result of the end of the Persian war was the need in Greece for organizing defense and equipping the army, Athens led the formation of the Delos Confederation, an alliance between several Greek city-states that were to contribute ships or money of the war.
The confederation of delos determined that large cities should provide troops and ships, while the smaller ones should pay a contribution to the Delos treasury. After the victory against the Persians, Athens forced the allied city-states to continue in the league, and transformed the contribution of money in taxes.
In 450 BCE, the league's treasure was transferred from Delos to Athens. Part of the league's money was spent rebuilding Athens, which reached its peak and became a maritime and commercial empire during the Pericles administration, which was also responsible for the construction of the Parthenon.
