Leonidas, one of the two kings in the Spartan diarchy, died fighting the Persian Invasion at Thermopylae. He had a force of three hundred Spartans, augmented by a thousand or so soldiers from his allies. He had sent the main part of his force in retreat, and was holding the pass at Thermopylae in order to give the Athenians and the other Grecian states more time to prepare against the Persians. <span />
The answer is A. Mycenaean civilization.
The Mycenaean civilization first developed on the mainland of modern-day Greece during the Bronze Age. The culture was made up mostly of a warrior aristocracy and was well-known for their military conquests. Around 1400 BCE, the Mycenaeans extended their control to Crete, which was then the center of the Minoan civilization. The Mycenaeans are also thought to have twice defeated the powerful city-state of Troy, though evidence of this is only depicted in stories such as those told in epic poems like Homer's Iliad.
