The Allies or Athenians forced more and more Greek cities to join so the league would be larger. The new members had to donate things or money just like the members that joined before. Even the Allies had to keep paying along with the old. In Athens most of the money was used to build beautiful buildings and art work. In time, some city-states tried a new form of government, called Democracy.
Democracy means rule by citizens.
The first people who built a democracy were the Athenians. The most important group in the government was the assembly. Each citizen was expected to go to meetings, it was considered their duty. At the meetings of the assembly, citizens would vote directly on important decisions affecting Athens. Women did not become full citizens, but they had lots of jobs as artists, poets, artisans, and they did a lot of work at home so the husband, father, or son could participate in government.
