Historical Context
Alexander the Great, born in 356 BCE, was the son of King Philip II of Macedon. By the time of the Battle of Granicus, he had already ascended to the throne following his father's assassination in 336 BCE and was eager to continue his father's campaign against Persia. Philip had united the Greek city-states under Macedonian hegemony, and after his death, Alexander sought to fulfill his father's ambition of conquering the Persian Empire.
The Persian Empire, at that time, was one of the largest empires in the world, stretching from the Mediterranean to the Indus River Valley. The Persian King Darius III was determined to defend his territory against the Macedonian threat. As Alexander crossed into Asia Minor, he encountered local satraps (governors) who were tasked with defending the Persian provinces.
The Prelude to Battle
Before engaging in battle, Alexander and his army of approximately 32,000 soldiers faced several significant challenges:
1. Terrain: The Granicus River was situated in a rugged region, which posed tactical difficulties. The narrow riverbanks limited maneuverability for both armies.
2. Intelligence Gathering: Alexander had to gather intelligence on Persian forces to assess their size and disposition. He learned that the Persian forces were estimated to be around 40,000 to 100,000 strong, comprising not only Persian soldiers but also Greek mercenaries.
3. Morale and Strategy: Alexander needed to boost the morale of his troops, who were outnumbered and facing the fearsome reputation of the Persian army. His leadership and charisma were crucial in rallying his men for the upcoming fight.
