How and when did Persia fall?

Answer 1

Persia, under the Achaemenid Empire, fell to Alexander the great in 330 BCE after a series of decisive battles, including the Battle of Gaugamela. The decline of the empire was exacerbated by internal strife and weak leadership, allowing Alexander to exploit these vulnerabilities. Following his conquests, the region transitioned through various dynasties, leading to the eventual establishment of Hellenistic rule. The fall of Persia marked the end of one of history's greatest empires.
