Why is the reign of Pericles considered the heyday of Athenian democracy?

Pericles, being the head of Athens, carried out many democratic reforms, allowed the Zeugites (the third estate according to property qualification) to occupy positions in the archonat, revived the “court of demes”, revived the previously existing “law on citizenship”. Pericles aspired to be a public politician, a public person. Under him, the Athenian temples were restored, the Parthenon, the statue of Athena, and other amazing structures were built.
