Alexander entered Egypt in the beginning of 331 BC. The Persian satrap surrendered and the Macedonians were welcomed by the Egyptians as liberators for they had despised living under Persian rule for almost two centuries. Here Alexander ordered that a city be designed and founded in his name at the mouth of river Nile, as trading and military Macedonian outpost, the first of many to come. He never lived to see it built, but Alexandria will become a major economic and cultural center in the Mediterranean world not only during the Macedonian rule in Egypt but centuries after.
In the spring of 331 Alexander made a pilgrimage to the great temple and oracle of Amon-Ra, the Egyptian god of the sun, whom the Greeks and Macedonians identified with Zeus Ammon. The earlier Egyptian pharaohs were believed to be sons of Amon-Ra and Alexander as new ruler of Egypt wanted the god to acknowledge him as his son. He decided to make the dangerous trip across the desert to visit the oracle at the temple of the god. According to the legend, on the way he was blessed with abundant rain, and guided across the desert by ravens. At the temple, he was welcomed by the priests and spoke to the oracle. The priest told him that he was a son of Zeus Ammon, destined to rule the world, and this must have confirmed in him his belief of divine origin. Alexander remained in Egypt until the middle of 331, and then returned to Tyre before facing Darius.
The Battle of Gaugamela
At Tyre, Alexander received reinforcements from Europe, reorganized his forces, and started for Babylon. He conquered the lands between rivers Tigris and Euphrates and found the Persian army at the plains of Gaugamela, near modern Irbil in Iraq, which according to the exaggerated accounts of antiquity was said to number a million men. The Macedonians spotted the lights from the Persian campfires and encouraged Alexander to lead his attack under cover of darkness. But he refused to take advantage of the situation because he wanted to defeat Darius in an equally matched battle so that the Persian king would never again dare to raise an army against him.
The two armies met on the battlefield the next morning, October 1, 331 BC. On the Persian side were numerous Asiatic nations - Bactrians, Indians, Medians, Sogdians, even Albanians from the Caucasus, the ancestors of the modern Albanians who many centuries later migrated to Europe and are now northern neighbors to the modern Greeks and western neighbors to the modern Macedonians. The survivors of the 50,000 Greeks which Darius had on his side at the beginning of the war were also among the Persian ranks.
At the beginning of the battle the Persian forces split and separated the two Macedonians wings. The wing of general Parmenio appeared to be backing down, but Alexander's cavalry rode straight after Darius and forced again his flight like he did at Issus. Darius fled to Ecbatana in Media, and Alexander occupied Babylon, the imperial capital Susa, and the Persian capital Persepolis, and was henceforth proclaimed king of Asia. Four months later, the Macedonians burned the royal palace in Persepolis, completing the end of the ancient Persian Empire.
Suppression of the Greek Rebellion, Discharge of the Greeks, and the Death of Darius
Meanwhile in Greece, the Greeks under the leadership of Sparta rose to a rebellion against the Macedonian occupation. Antipater was in Thrace at the time and the Greeks took the opportunity to push back the Macedonian forces. But their initial victory did not last for long as Antipater returned with a large army, defeated the rebels, and regained Greece. 5,300 Greeks, including the Spartan king Agis were killed, while the Macedonians lost 3,500 men.
In Asia, the news of the beginning of the Greek rebellion had Alexander so deeply worried, that he immediately sent money to Antipater to counter it. And when he learned that the Greeks were defeated, he proclaimed the end of the "Hellenic Crusade" and discharged all-Greek forces in his army. He no longer needed these hostages and potential troublemakers.
Alexander continued his pursuit of Darius for hundreds of miles from Persepolis. When he finally caught up to him, he found the Persian king dead in his coach. He was assassinated by Bessus, the satrap of Bactria which now proclaimed himself "King of the Kings", assuming the title of the Persian kings. Alexander gave Darius a royal funeral and set out for Bactria after his murderer.
The Trial of Philotas and the Murder of Parmenio
To win the support of the Persian aristocracy Alexander appointed many Persians as provincial governors in his new empire. He adopted the Persian dress for ceremonies, gave orders for Persians to be enlisted in the army, and encouraged the Macedonians to marry Persian women.
But the Macedonians were unhappy with Alexander's Orientalization for they were proud of their Macedonian customs, culture, and language. His increasingly Oriental behavior eventually led to conflict with the Macedonian nobles and some Greeks in the train. In 330 BC series of allegations were brought up against some of Alexander's officers concerning a plot to murder him. Alexander tortured and executed the accused leader of the conspiracy, Parmenio's son Philotas, the commander of the cavalry. Several other officers were also executed according to Macedonian law, in order to eliminate the alleged attempt on Alexander's life. During the trial of Philotas Alexander raised the question of the use of the ancient Macedonian language. He spoke:
"'The Macedonians are about to pass judgment upon you; I wish to know whether you will use their native tongue in addressing them.' Philotas replied: 'Besides the Macedonians there are many present who, I think, will more easily understand what I shall say if I use the same language which you have employed.' Than said the king: 'Do you not see how Philotas loathes even the language of his fatherland? For he alone disdains to learn it. But let him by all means speak in whatever way he desires, provided that you remember that he holds out customs in as much abhorrence as our language.'" (Quintus Curtius Rufus 6.9.34-36)
The trial of Philotas took place in Asia before a multiethnic public, which has accepted Greek as their common language. Alexander spoke Macedonian with his conationals, but used Greek in addressing the Greeks and the Asians, as Greek was widely taken as international language in ancient times. Like Carthaginian, Illyrian, and Thracian, ancient Macedonian was not recorded in writing. However, on the bases of about hundred glosses, Macedonian words noted and explained by Greek writers, some place names from Macedonia, and names of individuals, most scholars believe that ancient Macedonian was a separate Indo-European language. Evidence from phonology indicates that the ancient Macedonian language was distinct from ancient Greek and closer to the Thracian and Illyrian languages. Some modern writers have erroneously concluded that the Macedonians spoke Greek based on few Greek inscriptions discovered in Macedonia, but that is by no means a proof that the Macedonian was not a distinct language. Greek inscriptions were also found in Thrace and Illyria, the Thracians even inscribed their coins and vessels in Greek, and we know that both the Illyrians and the Thracians were not Greeks who had distinct languages.
After Philotas was executed according to the Macedonian custom, Alexander ordered next the execution of Philotas' father, general Parmenio. But the death of the old general did not sit well with every Macedonian in the army. Parmenio was a veteran, proven solder of Philip's guard, a men who played a major part in leading the Macedonian armies and rising the country to a world power. In fact Philip II had often remarked how proud he was to have Parmenio as his general.
The Murder of Cleitus and the execution of Callisthenes
Alexander next killed Cleitus, another Macedonian noble, in a drunken brawl. Heavy drinking was a cherished tradition at the Macedonian court and that day Cleitus publicly denounced the king before the present for the murders of Parmenio and Philotas. He went further by ridiculing Alexander for claiming to be "son of Ammon" and for denouncing his own father Philip II. Alexander lost his temper, snatched the spear from the bodyguard standing near, and ran Cleitus through with it. Although he mourned his friend excessively and nearly committed suicide when he realized what he had done, all of Alexander's associates thereafter feared his paranoia and dangerous temper.
He next demanded that Europeans, just like the Asians, follow the Oriental etiquette of prostrating themselves before the king - which he knew was regarded as an act of worship by the Greeks. But resistance put by Macedonian officers and by the Greek historian Callisthenes, the nephew of Aristotle who had joined the expedition, defeated the attempt. Callisthenes was soon executed on a charge of conspiracy, and we can only imagine how Aristotle received the news of his death. The two were already estranged for a long time before Callisthenes’ execution, as Alexander's letters to his former tutor carried unfriendly contents.
The Macedonians spent two hard years in Bactria fighting a guerilla war against the followers of Bessus and the Sogdian ruler Spitamenes. Finally, Bessus was caught and executed for the murder of his king Darius III, and Spitamenes was killed by his own wife which was tired of running away. Bactria and Sogdiana, the most eastern provinces of the Persian Empire came under Macedonian control. It is here that Alexander fell in love with and married the beautiful Sogdian princess Roxane.
