On May 22nd in 334 BC the Macedonian army led by Alexander the Great defeated Darius III’s Persian army in the Battle of the Granicus. The outcome from this victory was Alexander gaining half of Asia minor, the battle was fought in north-west Asia minor near the site of Troy, it was on the road from Abydos to Dascylium (near modern-day Eregli, Turkey) at the crossing of the Granicus river. Alexander defeated the forces of the Persian satraps of Asia Minor, including a large force of Greek mercenaries led by Memnon of Rhodes.
This battle was the first of three major battles fought between Alexander the Great and Persia. By the end of Alexander’s battles in Asia the Persian Empire of the Great King Darius III was crumbling and wanting peace from the seemingly unbeatable Macedonians.
