During the late nineteenth century, many anti-imperialists worried that imperialism might threaten United States democratic values by VIOLATING FUNDAMENTAL HUMAN RIGHTS, such as the right to have a government of their own, something that Imperialist countries were known to restrict on their colonies.
The Age of Pericles was between 461 B.C and 429 B.C when Pericles overtook Athenian Government and imposed direct democracy. By expanding the government and involvement of the Athenian people, it made every male citizen take part in mass meetings for government regulations.
Up until this day, Pericles is still the longest lasting democratic leader in Greece.
