Final answer:
True, Cleisthenes, an Athenian ruler of the 6th century BCE, reorganized the political system to create the first 'real' democracy, allowing all male citizens to vote and serve in public office.
Step-by-step explanation:
True, in the beginning of the 6th century BCE, the Athenian ruler named Cleisthenes did indeed reorganize the political system. After the fall of tyrannical rule following Pisistratus's death, Cleisthenes was instrumental in the establishment of a more democratic system in Athens. His notable reforms included the reorganization of the Athenian council to consist of 500 citizens, chosen by lot from each of the ten new tribes he created. This inclusion of poorer citizens, who previously could not afford to serve as hoplites, and the mixing of men of different backgrounds within these tribes, helped unite Athenians and decrease factionalism. Furthermore, Cleisthenes established the first 'real' democracy, where all male citizens were given the right to vote and serve in public office regardless of their wealth.
This democratic system persisted and was enhanced by subsequent leaders like Pericles, who expanded opportunities for citizens further, ensuring even those without wealth could serve in public office. The reforms made by Cleisthenes set the foundation for what would be considered one of the earliest examples of democracy, influencing future policies and governments in Athens.
