Background

The Persian campaign of Alexander the Great, spanning from 334 to 330 BCE, was a series of military operations aimed at overthrowing the Persian Empire ruled by Darius III. This campaign marked the beginning of Alexander's conquests and led to the eventual fall of one of the most powerful empires of the ancient world.

Background and Preparation

  1. Succession and Consolidation:
    • Philip II's Legacy: Alexander inherited a well-trained and disciplined army from his father, Philip II of Macedon, who had laid the groundwork for Macedonian dominance in Greece and prepared for an invasion of Persia.
    • Securing Greece: Before embarking on his Persian campaign, Alexander secured his position in Greece by quelling the Theban revolt and ensuring the loyalty of the other Greek city-states.

Initial Invasion and Early Battles

  1. Crossing into Asia Minor:

    • Hellespont Crossing (334 BCE): Alexander began his campaign by crossing the Hellespont (modern-day Dardanelles) into Asia Minor with an army of approximately 40,000 men.
    • Battle of the Granicus River: Alexander's first major engagement with Persian forces occurred at the Granicus River, where he secured a decisive victory. This battle opened up Asia Minor to his control.
  2. Securing Asia Minor:

    • Siege of Halicarnassus: Following his victory at the Granicus, Alexander besieged and captured the fortified city of Halicarnassus, solidifying his hold over Asia Minor.
    • Phrygia and Gordium: Alexander marched inland to the city of Gordium, where he famously cut the Gordian Knot, a symbolic act that prophesied the ruler of Asia.

Major Battles and the Advance into Persia

  1. Battle of Issus (333 BCE):

    • Confrontation with Darius III: At Issus, Alexander faced the main Persian army led by Darius III. Despite being heavily outnumbered, Alexander's tactical brilliance led to a decisive victory. Darius fled the battlefield, leaving his family and treasure behind.
  2. Siege of Tyre (332 BCE):

    • Strategic Importance: The island city of Tyre was a crucial naval base for the Persians. Alexander besieged Tyre for seven months, eventually building a causeway to the island and capturing the city. This victory secured Alexander’s control over the eastern Mediterranean coast.
  3. Conquest of Egypt:

    • Welcomed as Liberator: Alexander marched into Egypt, where he was welcomed as a liberator from Persian rule. He founded the city of Alexandria, which would become a major center of Hellenistic culture.
    • Visit to the Oracle of Amun: Alexander visited the Oracle of Amun at Siwa Oasis, where he was declared the son of Amun, reinforcing his divine status in the eyes of his followers.

Decisive Engagements and the Fall of Persia

  1. Battle of Gaugamela (331 BCE):

    • Final Confrontation with Darius III: The decisive battle of Gaugamela took place near modern-day Mosul in Iraq. Alexander employed superior tactics to defeat the numerically superior Persian forces. Darius III fled once again, marking the effective end of Persian resistance.
  2. Capture of Persian Capitals:

    • Babylon: After Gaugamela, Alexander captured Babylon without resistance, securing its wealth and strategic position.
    • Susa: Alexander moved on to Susa, another key Persian city, where he acquired enormous treasures.
    • Persepolis: The ceremonial capital of the Persian Empire, Persepolis, was captured and subsequently burned, symbolizing the end of Persian rule.

Pursuit and Death of Darius III

  1. Pursuit of Darius III:

    • Flight and Assassination: Darius III fled eastward, attempting to gather support. However, he was betrayed and killed by his own satraps, including Bessus, who declared himself king.
  2. Bessus and the Final Resistance:

    • Subjugation of Bessus: Alexander pursued Bessus into Central Asia, capturing him and dealing with remaining pockets of resistance. Bessus was executed, ending organized Persian resistance.

Consolidation of Power

  1. Administrative Reforms:
    • Integration of Persian Nobility: Alexander adopted elements of Persian dress and customs, married Persian nobles, and encouraged his officers to do the same to integrate the Macedonian and Persian elites.
    • Founding of Cities: Alexander founded numerous cities, many named Alexandria, to serve as administrative centers and spread Hellenistic culture.

Conclusion

Alexander the Great's Persian campaign was a monumental achievement that dismantled the Persian Empire and established Alexander as one of history's greatest military leaders. His conquests spread Greek culture and ideas throughout the known world, creating a new Hellenistic civilization that blended Greek and Eastern elements. This campaign not only transformed the political landscape but also had lasting cultural impacts that continued to influence the ancient world long after Alexander's death.

Battles of the Persian Campaign

Alexander landed safely on the shores of Anatolia but was faced with a geography problem. To the south of him was an area known as Mount Ida which had a river that snaked around it formed a natural boundary that prevented him for easily accessing the interior of the land. Alexander decided to cross the river with his massive army and all the supplies and send forward scouts known as prodromi to ensure the path was safe. After a while the scouts began reporting a gathering of Persian troops on the other side of the river that were going to make his crossing much harder.

Alexander continued the march of his men and called his generals together to formulate a strategy. One of his generals named Parmenio suggested that they should not try and cross the river right away because the Achaemenid forces generally consisted of cavalry and this could be beat another way. Parmenio came up with the strategy that the horses and men are separated at night and if their army was to storm the camp at night they would be able to overwhelm the men before they could mount a defense. Alexander did not agree with this plan however, and was confident his army could handle anything the Persians threw at them along the way. Alexander was also going for an early sort of shock and awe policy that if he continued marching and building momentum his reputation would precede him and he may avoid many battles in the future if he crushed the first opposition with such ferocity.

Battle of the Granicus (334 BC)

See Battle of the Granicus (334 BC)

What ensued was known as the Battle of the Granicus (334 BC) and is one of Alexander's most famous exploits against the Persian Empire. During this engagement Alexander was able to cross the Granicus river with his cavalry and soldiers and against all odds break through the Persian line.

This caused the Persians to scatter in all directions and despite sustaining possible heavy losses, Alexander had won and established a massive foothold in Anatolia. His following campaign through Anatolia would see the peaceful surrender of nearly all the city-states, with some inner-conflicts as the Persian and Greek factions all competed in the power vacuum created by Alexander's victory.
