"Las Helénicas" by Xenophon is a historical work written between 411 and 354 BCE. This chronicle covers pivotal events in ancient Greece, continuing where Thucydides' unfinished history ended. Xenophon narrates the final years of the Peloponnesian War, Athens' defeat and subsequent tyranny, Sparta's rise to dominance, and the eventual shift of power to Thebes. Through major battles, political intrigues, and shifting alliances, the work captures a turbulent half-century that reshaped the Greek world.
