King Leonidas of Sparta.
Back in ancient times it was the place of battle between the Spartans led by Leonidas and the Persians led by Xerxes. The modern-day location is simply Thermopylae, Greece. Hope that helps. :-)
Their king, Xerxes I.
Leonidas I was the land commander. Themistocles led the navy
The pass of Thermopylae was used by peoples for thousands of years as a route between northern and southern Greece, first by nomadic peoples, then for trade and invasion. This led the Persians to use it as their route into southern Greece when they invaded in 480 BCE.
King Leonidas
A coalition of Greek cities led by Sparta.
There were a dozen city-states involved in the battle, one of which was a contingent from Sparta led by their king Leonidas.
The invading Persian army and a consortium of southern Greek city-states led by Sparta.
The "300" were Spartan hoplite soldiers led by their king Leonidas who fought at the battle of Thermopylae .
The battle of Thermopylae was fought between Greek mainland cities led by Sparta and a Persian invading army. If you have ever seen the movie 300 that's what it is. But there were also about 5,000 non-Spartan troops with the Spartans.
The Persians won the Battle of Thermopylae, led by Xerxes I. But Greece won the war. The Battle of Thermopylae happened in ancient Greece where 700 men made their final stand against the 300,000 Persians there were 300 hundred Spartans as well as 400 Greek soldiers from other city states. It is important to note that the Persian Victory came at a very high price. The Thespian and Spartan troops that fought and sacrificed their lives at the Battle of Thermopylae successfully weakened the Persian land forces to such an extent that naval victories like Salamis were able to convince the Persians to retreat.
There was a coalition of Greek forces numbering about 4000 at Thermopylae. The coalition was led by King Leonidas and 300 Spartans.
