Sparta's reason is that they failed for military reasons and they went to war with Athens. Athen's reason is that they were conquered by the Roman Empire.
If you are talking about Cities States and the Peloponnesian War is mainly because half of the states were in ally with Sparta and the other half were allies with Athens, plus some other neutral states. Sparta and Athens were the two dominant states back then, so when Athens started to gain more and more power, Sparta didn't like that. The possible reason why Sparta and Athens were in dispute all the time might be the governmental system, Sparta had an oligarchic system, and Athens a democratic system. Was like nowadays political parties.
The Athenian view was that Sparta was jealous of Athens' preeminence in the Hellenic world. The ultimate sticking point was Sparta's demand that Athens should withdraw the ruinous trade embargo against Megara, one of Sparta's allies. The Athenian viewpoint was that if they acceded to this, they would be effectively obeying Sparta's orders, and thereafter expect other orders to follow. Athens saw itself as strategically more powerful than the Spartan alliance, having the revenues from its empire to maintain its dominant naval power, and the ability to defend itself behind the city and long walls, with access to the sea to resupply itself. It saw no reason to accede to Spartan demands, which would also weaken and threaten its standing in its empire.
i can answer correctly only about Sparta. the town is heard for the first time from ancient Achaioi and its king Menelaos and his queen Helen of Troy, which is considered as the reason of the Troyan War. That era ended when Dorians came from the north and the new era starts. It is known as the Sparta of King Leonidas, as a very strict city where the Spartan's proffession is simply war ( ex. wars with the Persians), that era ends when Sparta is occupied by Alexander the great. in between there was the Peloponnesean war between Sparta and Athens and their allies and the defeat of Athens. Practically both of them lost. That is the reason why it was occupied by Alexander the great sice they were coming from a 30-year-old war. Long after Macedonians came the Romans and I think that is very very shortly the history of Sparta. Thebes is a city with common background as Sparti. it is close to Athens and it was one of their rivals In about 379/8 bc Thebes broke free of Spartan oppression and undertook a war with Sparta in that ultimately led to Sparta's fall, after which Sparta allied with Athens and waged war with Thebes and brought Thebes back down.
Athena and Poseidon were rivals in the contest for Athens. When Athena won and became the patron goddess of the city, there were still some tensions between the two. The other reason why Athena hated Poseidon was because she caught him and his girlfriend Medusa in her temple and felt very insulted.
There were many battles between Athens and Sparta. They also fought on the same side several times. There was a war between Athens and its allies and Sparta and its allies, which we now call the Peloponnesian War (431-404 BCE) for no good reason, as it was fought throughout the Mediterranean from Sicily to Asia Minor. It contained many battles. Did you have one in particular in mind?

Greece did not exist as a country in Ancient World. There were numerous Greek-city states including Athens, Sparta, Argos, Corinth just to name a few. The main reason a war broke out between Athens, its allies and the Peloponnesian league, was due to many reasons, such as Sparta's need to train in real war situations (Sparta didn't wage war very often) and battles for territory.
Athens and Sparta were both culturally Greek so there is no point in saying they were culturally diverse and there was a geographic reason for difference.
Athens converted the power and finances of the ant-Persian league to its own benefit and intervention in the affairs of the Greek cities. The vulnerable city-states joined a league with Sparta to oppose this. Athens' continuing aggressiveness brought Sparta's league to a final showdown over Megara, and when Athens would not back down, war was declared. Neither side foresay 27 years of destructiveness throught the whole Greek world, from Sicily to Asia Minor.
Athens fought off a punitive expedition from Persia.
"What is the conflict between Good and Evil?" (Not to say Athen is good, Sparta - Evil, I just mean they are two polarities, they just can't seem to get on) Sparta thought Athens was getting too powerful so they decided to show them a thing or two, Athens should have won, if it weren't for the death of their leader Pericles, at the hands of the plague. Sparta won and Athens lost her empire. Sparta did not gain it however, she liberated each state to rule themselves. We call it the Peloponessian War today. The two cities were polar in most cultural respects, but they cooperated in defeating Persia in the Second Persian War. After the war Athens got most of the credit, intensifying the existing rivalry between them. It was primarily a political conflict about which city should be Number One in Greece.Another View:The Peloponnesian War 431-404 BCE was fought between Sparta and its allies and Athens and its allies (empire).Sparta and Athens were allies and respected each other for many years. They cooperated against Persia, Sparta sending a contingent to Athens to help defend against Persia's attack on Athens in 490 BCE, but it arrived too late, after the battle of Marathon had been fought. Cooperation continued, but it came adrift when the Athenian contingent sent to help Sparta put down a rebellion of its serfs in 461 BCE went awry when the Spartans realised that the Athenians were sympathetic to the opposition, and sent the Athenians home.After the Persian War ended in 449 BCE, Athens opportunistically converted the Delian League of eastern Greek cities it had led against the Persian Empire into an empire of its own, and lived high on the hog with the war funds it continued to extort from those cities, turning the League into an empire of its own - the cities effectively held off an invader only to be taken over by their own leader.Athens, overconfident with this success and money, kept interfering in other Greek cities not inside its empire, bringing it into conflict with members of the Peloponnesian League led by Sparta. Athens destroyed the Corinthian fleet, and finally tried to bankrupt Megara, one of these cities. The Peloponnesian cities appealed to Sparta, which demanded that Athens back off. It didn't and the devastating 27-year Peloponnesian War 431-404 BCE ensued.The irony was that Persia had its revenge on Athens by bankrolling a fleet for the Peloponnesian League which could match the hitherto-dominant Athenian fleet on which its power and empire rode.Further consequences: The reason for the Persian Wars was that Persia tried to stop western Greek cities interfering in the peace within its empire by bringing the cities outside its empire under control. With Athens the chief troublemaker, the Persians thought 'better a Peloponnesian dominance than an Athenian dominance'. After the Peloponnesian War ended in Athens' defeat and loss of its empire, the Greek cities went on fighting each other in shifting alliances and - another irony - Persia imposed the King's Peace, threatening retaliation if their endless fighting continued to spill over into the Persian Empire, which was the cause of the Persian Wars the previous century in the first place. And while Persia had the advantage over the war-weakened Greek cities, it resumed control of the Greek cities in Asia Minor which it had lost after the Persian War over 60 years earlier.
