Answer:
The correct answer is: Cleisthenes.
Step-by-step explanation:
Cleisthenes was a lawgiver from Ancient Greece, particularly from Athens, that had a big role in reforming the constitution and setting Greece on a democratic path - for these events is that he is known as the father of Athenian democracy.
Born from aristocratic parents, Cleisthenes took power from the nobility and gave it to the citizens, which soon enlarged his following and made the rise of an Athens with equal rights for all its citizens possible. This is why Cleisthenes is known as the man that would banish the aristocratic rule.
Along with this form of democracy, came ostracism: a policy that established that any citizen that would threaten the state would be expelled from Athens for a period of 10 years.
