How did alexander’s attempt to make his empire secure lead to the hellenistic age?

Alexander was conscious that his empires spanned several nations and cultures and he considered that the unifying factor was the Enlightened Greek Classical Culture. He did however try to hybridize local cultures with Greek cultures in order to homogenize his empire and provide it with political and cultural stability. He favored the influx of Greek settlers to all the lands he conquered and established military garrisons and imposed Greek legal rule. Despite the rejection of his hybridization attempts by both his Greek and non-Greek subjects, Greek culture, Science and Arts greatly influenced all the lands that he conquered. The fact the after his death his competing generals ultimately divided his empire in autonomous Greek Empires and Kingdoms further spread Greek culture since they did not seek to hybridize the culture but to impose it on the conquered territories. Although these populations resisted such acculturation, they were inevitably influenced by the Greek ways of the ruling Greek minority.
