Religious Change
Alexander invaded Phonecia and learned about the god Ammon. According to Arrian of Nicomedia, Alexander did this because he wanted to be like his legendary ancestors Perseus and Heracles. He did this because he wanted to be just like them and consider himself a god just like they are. (Jona Lendering)
While he was visiting here and conquering land, he learned about the god ammon. He was a figure similar to heracles and had the horns of a ram. He thought he was the son of this god and basically forced Greeks to adopt this god. (Jona Lendering)
Alexander from then on was greeted as Ammon's son, and started to believe that he was a demi-god. According to Ephippus of Olynthus, Alexander sometimes wore the horns of his divine father Ammon on public occasions. It is certain that immediately after his death, he was depicted in this fashion. The greeks created coins of Alexander with horns and they started to believe, after his death, that he may have been the son of this god. (Jona Lendering)

Arts and Culture
While conquering Persia, Alexander had to show that he was also a Persian leader, so he started to adopt Persian culture and art. He whore what a royal Persian would where. He had his artists depict him as a Persian King as well. It is even said by Arrian that Ammon, one of Alexander's legendary ancestors wore a diadem and purple and white striped tunic just like Alexander was wearing. Although his army did not like it, they were forced to come to terms with it, and even back in Macedonia people started dressing like that because a god was said to be dressing like that. (Jona Lendering)
Expansion of the Greeks
The most obvious short term impact was that now the Macedonian empire was spread though all of Asia. Alexander and his people now owned all of this land and were free to do whatever they want with it. Shortly after Alexander's death they lost all of this land, but the most immediate impact was their ownership of this new land. They used the land for farming and housing all of the people they had conquered. He conquered and founded over 100 different cities just named Alexandria. He conquered so many different states throughout his entire conquest and took over so many different places. He had such a large effect on how much more area he gave the Macedonians and how far he extended his empire. He effected all of those states as well not in a positive way, but he changed them. He got so much land more his people and changed the dynamic of their kingdom to a completely new and much more powerful place. This changed very quickly, but it was a very large and immediate short term effect of what Alexander the Great did. (Jona Lendering)
Magians
According to the Persians, Alexander resembled one of the helpers of Angra Mainyu, 'the hostile spirit', the personification of evil in the Persian Religion. It is believed in the Avesta, that some of the writings about Angra Mainyu was written during the time of Alexander the Great becuase he was so brutal(Jona Lendering)
During this time, Alexander had religious specialists known a Magians who would help communicate their religion to the Persian's religion. Greek sources frequently mention the Magians at Alexander's court performing their usual incantations and prayers. This proves that there was collaboration and, that Alexander asked the Magians for advice. It is also certain that Alexander's teacher, the philosopher Aristotle, published a book that was called The Magian. It is now lost, but it is mentioned in the History of philosophy by Diogenes Laertius and it probably contained a positive evaluation of the teachings of the Magians. (Jona Lendering)
These Magians were a combined people of both the Greek and Persian religion. He asked them for religious advice of the Persian gods. Aristotle even wrote books about them, as did other famous historians. These people changed the Greek religion a lot. Alexander adopted some of there concepts and ways, which were then passed on to the rest of the Greeks. Alexander learned all about religion from these Magians, and those teachings were then passed on to common Greek people, and it was cultivated into their common Greek religion. (Jona Lendering)
