The Battle of Issus (333 BC) was a major clash between Alexander the Great and Darius III of Persia. Think of it as the ultimate showdown between two undefeated bosses in a video game. Alexander's victory opened the way for his conquest of the Persian Empire. It's not just any battle; it’s a turning point in world history, marking the decline of Persian power and the rise of Greek influence. The strategies used are still studied today.
