Answer:
He helped the spread of democracy.
He ordered the building of the Parthenon.
He rebuilt Athens after it had been ruined by war.
He made Athens a center for learning and the arts.
Step-by-step explanation:
Pericles was an Athenian politician, rhetorician and reformer of Athenian democracy.
Paradoxically, although the power in the polis was concentrated in his hands, he created the Athenian democracy. In the years between 444 and 429 BCE he was elected annually as a strategist, that is, a military commander who also had an influence on the politics of Athens. He expanded and strengthened the democratic system, and took care of philosophers and artists. He also used the saved money to build magnificent buildings, such as the Parthenon.
Pericles also took care of the development of Athens' influence by establishing colonies along the Black Sea coast. He also expanded Piraeus (it was the most important port of ancient Athens), leading to Athens' commercial advantage in the Aegean Sea, which caused the conflict with Sparta in the Second Peloponnesian War.
