What were the effects of the Persian Wars on Athens’ economy

During the final phase of the war, Athens led the Delian league to which other cities contributed either ships of money. Most found it easier to give money, so Athens was able to maintain a superior fleet and continue to extort the money even after peace was made with Persia.

This money was diverted to beautifying the city and keeping half its population on the public payroll, as well as keeping up the dominant naval power to continue collecting the money and extend Athens’ commercial interests.
