How did the peloponnesian war contribute to the expansion of mancedonia?

Answer 1

Although thr Greek city-states were devastated by the war, they continued to fight each other in varying alliances for the next 50 years. The three principal cities in all this - Athens, Sparta and Thebes - were by then so debilitated that they could not provide sufficient opposition to prevent the growing Macedonian ascendency in the vacuum they had themselves created.
