What factor besides the peloponesian war finally brought an end to the Athenian government of Pericles?

Besides the Peloponnesian War, the plague that struck Athens in 430 BCE significantly weakened the Athenian government under Pericles. The outbreak decimated the population, including many soldiers and key leaders, leading to social and political instability. Additionally, the loss of manpower and resources diminished Athens' ability to sustain its military efforts, ultimately contributing to the decline of its democratic governance.
