It's time for Athenians to make their own decisions!
But the aristocratic families did not like the way that he ruled. So for that reason, under the rule of Isagoras, they drove him out of the city with the help of the Spartans. Isagoras completely removed Solon's power and attempted to turn it into an oligarchy.
The Athenians hated that fact they no longer had a choice in things so they fought back. After defeating the leaders they brought back in Cleisthenes to continue ruling and from there he created the world first democracy. From there he created tribes, created ostracism, general assembly, and gave all Athenian the right to vote and also lowered the power of the Areopagus.
