News then reached Alexander that Cleitus, King of Illyria, and King Glaukias of the Taulantii were in open revolt against his authority.

Battle of Thebes

-335 Dec 1 -

Thebes, Greece

While Alexander campaigned north, the Thebans and Athenians rebelled once again. Alexander immediately headed south. While the other cities again hesitated, Thebes decided to fight. The Battle of Thebes was a battle that took place between Alexander III of Macedon and the Greek city state of Thebes in 335 BC immediately outside of and in the city proper. After having been made Hegemon of the League of Corinth, Alexander had marched to the north to deal with revolts in Illyria and Thrace. The garrison in Macedonia was weakened and Thebes declared its independence. The Thebans refused to submit on merciful terms, and he assaulted the city, took it, and sold all the survivors into slavery. With the destruction of Thebes, mainland Greece again acquiesced in Alexander's rule. Alexander was now finally free to undertake the Persian campaign which had been planned for so long by his father.

He showed his intent to conquer the entirety of the Persian Empire by throwing a spear into Asian soil and saying he accepted Asia as a gift from the gods. This also showed Alexander's eagerness to fight, in contrast to his father's preference for diplomacy.


Battle of the Granicus

The battle took place on the road from Abydos to Dascylium (near modern-day Ergili, Turkey), at the crossing of the Granicus River (modern-day Biga Çayı). After an initial victory against Persian forces at the Battle of the Granicus, Alexander accepted the surrender of the Persian provincial capital and treasury of Sardis; he then proceeded along the Ionian coast, granting autonomy and democracy to the cities.

He offered a peace treaty that included the lands he had already lost, and a ransom of 10,000 talents for his family. Alexander replied that since he was now king of Asia, it was he alone who decided territorial divisions.

When Alexander destroyed Tyre, most of the towns on the route to Egypt quickly capitulated. However, Alexander met with resistance at Gaza. The stronghold was heavily fortified and built on a hill, requiring a siege. When "his engineers pointed out to him that because of the height of the mound it would be impossible... this encouraged Alexander all the more to make the attempt".

Battle of the Persian Gate

-330 Jan 20 -

Yasuj, Kohgiluyeh and Boyer-

The Battle of the Persian Gate was a military conflict between a Persian force, commanded by the satrap of Persis, Ariobarzanes, and the invading Hellenic League, commanded by Alexander the Great. In the winter of 330 BC, Ariobarzanes led a last stand of the outnumbered Persian forces at the Persian Gates near Persepolis, holding back the Macedonian army for a month. Alexander eventually found a path to the rear of the Persians from the captured prisoners of war or a local shepherd, defeating the Persians and capturing Persepolis.

-330 May 1 -

Marvdasht, Iran

Alexander sent the bulk of his army to the Persian ceremonial capital of Persepolis via the Persian Royal Road. Alexander himself took selected troops on the direct route to the city. He then stormed the pass of the Persian Gates (in the modern Zagros Mountains) which had been blocked by a Persian army under Ariobarzanes and then hurried to Persepolis before its garrison could loot the treasury. On entering Persepolis, Alexander allowed his troops to loot the city for several days. Alexander stayed in Persepolis for five months. During his stay a fire broke out in the eastern palace of Xerxes I and spread to the rest of the city. Possible causes include a drunken accident or deliberate revenge for the burning of the Acropolis of Athens during the Second Persian War by Xerxes. Even as he watched the city burn, Alexander immediately began to regret his decision. Plutarch claims that he ordered his men to put out the fires, but that the flames had already spread to most of the city. Curtius claims that Alexander did not regret his decision until the next morning.

Media, Iran

Alexander then chased Darius, first into Media, and then Parthia. The Persian king no longer controlled his own destiny, and was taken prisoner by Bessus, his Bactrian satrap and kinsman. As Alexander approached, Bessus had his men fatally stab the Great King and then declared himself Darius' successor as Artaxerxes V, before retreating into Central Asia to launch a guerrilla campaign against Alexander. Alexander buried Darius' remains next to his Achaemenid predecessors in a regal funeral. He claimed that, while dying, Darius had named him as his successor to the Achaemenid throne. The Achaemenid Empire is normally considered to have fallen with Darius.


Central Asia

-330 Sep 1 -


Alexander viewed Bessus as a usurper and set out to defeat him. This campaign, initially against Bessus, turned into a grand tour of central Asia. Alexander founded a series of new cities, all called Alexandria, including modern Kandahar in Afghanistan, and Alexandria Eschate in modern Tajikistan. The campaign took Alexander through Media, Parthia, Aria (West Afghanistan), Drangiana, Arachosia (South and Central Afghanistan), Bactria (North and Central Afghanistan), and Scythia.


Siege of Cyropolis

-329 Jan 1 -

Khujand, Tajikistan

Cyropolis was the largest of seven towns in the region that Alexander the Great targeted for conquest in 329 BC. His goal was the conquest of Sogdiana. Alexander first sent Craterus to Cyropolis, the largest of the Sogdian towns holding out against Alexander's forces. Craterus' instructions were to "take up a position close to the town, surround it with a ditch and stockade, and then assemble such siege engines as might suit his purpose....".

Accounts of how the battle went differ among authors. Arrian cites;Ptolemy;as saying Cyropolis surrendered, and Arrian also states that according to;Aristobulus;the place was stormed and the town's inhabitants were massacred. Arrian also cites Ptolemy saying that he distributed the men among the army and ordered that they should be kept guarded in chains until he should depart from the country, so that none of those who had affected the revolt should be left behind.

Battle of Jaxartes

-329 Oct 1 -

Fergana Valley, Uzbekistan

Spitamenes, who held an undefined position in the satrapy of Sogdiana, betrayed Bessus to Ptolemy, one of Alexander's trusted companions, and Bessus was executed. However, when, at some point later, Alexander was on the Jaxartes dealing with an incursion by a horse nomad army, Spitamenes raised Sogdiana in revolt. Alexander personally defeated the Scythians at the Battle of Jaxartes and immediately launched a campaign against Spitamenes, defeating him in the Battle of Gabai. After the defeat, Spitamenes was killed by his own men, who then sued for peace.

Battle of Gabai

-328 Dec 1 -

Karakum Desert, Turkmenistan

Spitamenes was a Sogdian warlord and the leader of the uprising in Sogdiana and Bactria against Alexander the Great, King of Macedon, in 329 BC. He has been credited by modern historians as one of the most tenacious adversaries of Alexander.

Spitamenes was an ally of Bessus. In 329, Bessus stirred a revolt in the eastern satrapies, and the same year his allies began to be uncertain about supporting him. Alexander went with his army to Drapsaca, outflanked Bessus and sent him fleeing. Bessus was then removed from power by Spitamenes, and Ptolemy was sent to catch him. While Alexander was founding the new city of Alexandria Eschate on the Jaxartes river, news came that Spitamenes had roused Sogdiana against him and was besieging the Macedonian garrison in Maracanda.

Too occupied at that time to personally lead an army against Spitamenes, Alexander sent an army under the command of Pharnuches which was promptly annihilated with a loss of no less than 2000 infantry and 300 cavalry.

The uprising now posed a direct threat to his army, and Alexander moved personally to relieve Maracanda, only to learn that Spitamenes had left Sogdiana and was attacking Bactria, from where he was repulsed with great difficulty by the satrap of Bactria, Artabazos II (328 BC). The decisive point came in December 328 BC when Spitamenes was defeated by Alexander's general Coenus at the Battle of Gabai. Spitamenes was killed by some treacherous nomadic tribes' leaders and they sent his head to Alexander, suing for peace. Spitamenes had a daughter, Apama, who was married to one of Alexander's most important generals and an eventual Diadochi, Seleucus I Nicator (February 324 BC). The couple had a son, Antiochus I Soter, a future ruler of the Seleucid Empire.
