The fall of the Persian Empire
In 330 BC, Alexander III, a young Macedonian king, invaded Iran and overthrew the Achaemenid dynasty. It is said that when Alexander burned the palace and its library at Persepolis, he destroyed a complete copy of the Avesta written in gold on twelve thousands goatskins.Shortly after his victories, however, Alexander became ill and died in Babylon. His vast empire then was divided among his generals. One, Seleucus, became the ruler of Iran and found the Seleucid dynasty. Seleucid rulers were not Zoroastrians. They worshipped Greek gods and goddesses.
