Why Was Sparta Considered The First Messenian War?

From the beginning of Sparta, in 900 BC, until their fall, in 192 BC, they were the superior fighting warriors across the Mediterranean sea and in the European vicinity. The spartans were the strongest, most fierce, and most feared people in Europe at the time with a highly militarized lifestyle and society. The spartans were the ultimate “super soldiers” of their time, the reason for this being, from the age of 7 all boys were required to go to military training at the Agoge and train there until the age of 20, they also had unique and extremely effective formations, ways of protection, and weapons (shields, long spears, etc.) that would help them in any scenario one could think of. In Sparta, when a boy is born soldiers would to the house
this war started the rise of sparta. During the Second Messenian War, Sparta became a local power in Peloponnesus and the rest of Greece. By the end of the second war, Sparta's reputation as a land-fighting force was unmatched.
The first Messenian war was a war between Messenia and Sparta. It began in 743 BC and ended in 724 BC (known as a the war where they fought in the time of the fathers of our fathers). This war resulted in Sparta`s victory and with this victory came the depopulation of Messenia by emigration of the Achaeans to other states and those who did not emigrate were turned into Serfs or Helots.
In 685 B.C. there was a revolt by the helot population of Messenia, which initiated the Second Messenian war (which ended in 668).

This war helped the Spartan society become a strong militaristic power in the Mediterranean area (which helped control the masses along the Peloponnese) and also stopped Any further revolts and rebellions from the Helots ,who eventually broke free from sparta control in 350
The league was organized with sparta as their hegemon (the leader/controller of a country or group of people) and was made up of two branches: the assembly of Spartiates and the Congress of Allies. Each allied city-state had one vote in the Congress, no matter how big their city was or geopolitical power. When in war one third of the military of a state could be requested, but other than that there were no required paid tributes in being in the alliance. Each alliance was made with Sparta and Sparta only, so that if the other city-states wanted to rally with another city-state they could but did not have to. although each state had one vote, League resolutions were not binding on Sparta, this meant that the “Peloponnesian Alliance” was not really an alliance at all, but just a way for sparta to become a stronger force all together. In return Sparta provided protection and security for all city-states within the alliance. After the Persian Wars the League was expanded into the Hellenic League and included Athens and other
