Achaemenid EmpireThe Achaemenid Empire or Achaemenian Empire (əˈkiːmənᵻd; 𐎧𐏁𐏂, Xšāça, ) was the ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC, also known as the First Persian Empire. Based in Western Asia, it was the largest empire the world had ever seen at its time, spanning a total of from the Balkans and Egypt in the west to Central Asia and the Indus Valley in the east. Around the 7th century BC, the region of Persis in the southwestern portion of the Iranian plateau was settled by the Persians.
Peloponnesian WarThe Peloponnesian War (Πόλεμος τῶν Πελοποννησίων) (431–404 BC) was an ancient Greek war fought between Athens and Sparta and their respective allies for the hegemony of the Greek world. The war remained undecided for a long time, until the decisive intervention of the Persian Empire in support of Sparta. Led by Lysander, the Spartan fleet, built with Persian subsidies, finally defeated Athens and started a period of Spartan hegemony over Greece. Historians have traditionally divided the war into three phases.
SpartaSparta was a prominent city-state in Laconia in ancient Greece. In antiquity, the city-state was known as Lacedaemon (Λακεδαίμων, Lakedaímōn), while the name Sparta referred to its main settlement on the banks of the Eurotas River in Laconia, in south-eastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece. Given its military pre-eminence, Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Athens.
HelotsThe helots (ˈhɛləts,_ˈhiːləts; εἵλωτες, heílotes) were a subjugated population that constituted a majority of the population of Laconia and Messenia – the territories ruled by Sparta. There has been controversy since antiquity as to their exact characteristics, such as whether they constituted an Ancient Greek tribe, a social class, or both. For example, Critias described helots as "slaves to the utmost", whereas according to Pollux, they occupied a status "between free men and slaves".
