What was the major effect of the peloponnesian war?

Answer 1

A major outcome of the Peloponnesian War was that Athens lost its empire and consequently the source of revenue which had supported its dominant navy. Sparta and its allies achieved temporary land dominance until this was overthrown by Thebes and its allies, leaving a three-way standoff in dominance in mainland Greece.

The widespread destruction of the 27-year war left the whole Hellenic world less united and capable of confronting Persia. Indeed, the defeat of Athens had been facilitated by Persia's intervention on the side of the Spartan alliance. The postwar division and ongoing struggles between Athens, Sparta and Thebes enabled Persia to intervene in Hellenic political arrangements - coming back from its conclusive defeats of the 5th Century to being able to dictate the King's Peace to the weakened and internally opposed Greek cities and leagues.

This weakened situation left mainland Greece open to the expansion of Phillip II of Macedonia, who established himself as Hegemon (leader, not ruler) of Greece, who then determined to eliminate the Persian dominance. After his assassination, his son Alexander was able to impose his own hegemony on the Greek states and, using the combined resources of Greece, proceed with his father's planned destruction of the Persian empire.

Answer 2

Laconian hegemony over the region for the following three decades, until Sparta's dominance was replaced by that of Thebes. The ongoing wars so debilitated the Greek cities that it became easy for Philip II of Macedonia to establish Macedonian hegemony.

Answer 3

The Golden Age of the Greek City-states ended with the war.

Addition:

The Greek world from Sicily to Asia Minor was devastated and weakened. Athens lost its empire, and its strenght waned thereafter. Warfare continued spasmodically between the Greek city-states, the weakness first allowing the Persian empire to impose peace on them, and allowing the rise of Macedon to become the dominant power in the eastern Mediterranean.

Answer 4

The Peloponnesian war was fought in Greece between Sparta and its allies (Peloponnesian League) and Athens and its empire. It was caused by Athens, having converted the Delian League, which it led against the Persian Empire, into an empire of its own, and used this power to intervene in the affairs of the Peloponnesians, leading to war between the two leagues. Athens lost the war and was stripped of its empire, becoming a second rate power. In usual Greek fashion, sporadic warfare continued amongst the Greek city-states, Sparta became dominant until it was replaced by Thebes. Greece became so weakened that it was easy meat for a takeover by Macedonia.

Answer 5

Sparta eclipsed Athens as the leading political power in Greece.

Answer 6

they lasted for 27 years
