Greek democracy was established because of the idea that a person
shouldn't be too powerful and rule the lives of others. They were so
ruthless at it that they would choose people to rule and then if they
became too powerful and popular they would exile them or punish them or
similar things. It was a kind of mob mentality that supported new and
popular people. It was not very democratic however according to modern
understanding of democracy because many were not allowed to vote at all,
including slaves who existed as an entire social class.
After the Persian Wars, the Greeks were worried about the Persians coming back to ate like Greece and destroy more city-states so all of Greece (excluding Sparta) formed the Delian League. Athens slowly dissolves this league by using its persuasive voice, "maybe we should move our treasury to Athens because we'll be handling the money" and since Athens was smart, many Greek city-state followed blindly, " ok, oops we just handed all of our money and freedom the the Athenians" This almost empire/league freed almost all Greeks from Persian control and a leading politician lead Athens to do become an empire, ask greek city-states for steady payments (taxes) and demanding loyalty (no freedom). This leading politician was Pericles, you need to know about Pericles to explain how the Delian league formed into an empire, Pericles even used the league's treasury to rebuild Atens and guided Athens for 30 years and even through the Peloponnesian war.
