اسکندر در ایران — چگونه یک مقدونی شاهنشاهی ایران را فتح کرد
Alexander of Macedon (356–323 BC) crossed into Asia Minor in 334 BC with an army of 40,000. Within a decade, he conquered the entire Achaemenid Persian Empire — defeating Darius III at Issus (333 BC) and the decisive Battle of Gaugamela (331 BC), capturing the royal capitals Persepolis, Susa, and Ecbatana.
Alexander's relationship with Persia was complex — not merely conquest. He adopted Persian court customs, married Persian royalty (Roxana, then Stateira, daughter of Darius III), encouraged his officers to marry Persian women, incorporated Persian elite cavalry and soldiers into his army, and styled himself King of Persia and successor to the Achaemenid kings.
After Alexander's death in 323 BC, the Seleucid Empire (one of the successor states) ruled most of Persia and deliberately blended Macedonian Greek and Persian culture. The resulting Hellenistic civilization spread Greek theater, philosophy, and science while absorbing Persian art, religion, and administrative expertise. Iranian nationalists regard Alexander's conquest as a tragedy; historians see it as the crucible of an extraordinary cultural synthesis.
Ancient sources disagree: some say it was revenge for the Persian burning of Athens (480 BC), others that it was a drunken decision, others a deliberate political statement. The ruins suggest a partial, targeted fire rather than total destruction.
After Alexander's death, the Seleucid Empire governed Persia for about 150 years. The Parthian Arsacid dynasty then overthrew the Seleucids around 247 BC, restoring Iranian rule and consciously preserving Persian culture through the Hellenistic era.
