What led to the fall of the Persian empire
user
The Persian empire was destroyed by Alexander the Great’s conquest in the late 4th century BC.  When Darius III, the last of the Achaemenid kings, tried to reclaim the kingdom Alexander ruled, he was defeated, captured, and died in captivity.  This led to the establishment of Alexander’s Hellenistic empire.

The Persian Empire was very successful for hundreds of years, but it finally fell to the Greeks in the 4th century BCE.  The main reasons for the fall were:

1.  The Persians’ military was not as strong as that of the Greeks, and the Greeks won several battles that weakened the Persian empire.

2.  The Persians were not great at managing their resources.  They had a lot of wealth, but they weren’t very good at using it to benefit their people.

3.  The Persians were unable to tolerate different cultures and beliefs.  As a result, they experienced constant revolts.

4.  The Persians were mostly interested in expanding their empire rather than in the day-to-day running of the empire.  This caused problems with logistics and with the general population.
