What kind of relationship did Athens have with other city-state?

Athens had a complex and often competitive relationship with other city-states in ancient Greece. It was a leading city-state in the Delian League, which aimed to counter Persian influence, fostering a sense of unity among its members but also asserting Athenian dominance. This often led to tensions, particularly with rivals like Sparta, culminating in the Peloponnesian War. Overall, Athens' relationships were marked by both alliances and conflicts, influenced by its democratic ideals and military power.
