Alexander The God King

Alexander's most obvious legacy was the introduction of Macedonian rule to huge new swathes of Asia. Many of these areas would remain in Macedonian hands, or under Greek influence for the next 200–300 years. The successor states that emerged were, at least initially, dominant forces during this epoch, and these 300 years are often referred to as the Hellenistic Period.

The eastern borders of Alexander's empire began to collapse even during his lifetime. However, the power vacuum he left in the northwest of the Indian subcontinent directly gave rise to one of the most powerful Indian dynasties in history. Taking advantage of the neglect shown to this region by the successors, Chandragupta Maurya (referred to in European sources as Sandrokotto), of relatively humble origin, took control of the Punjab, and then with that power base proceeded to conquer the Nanda Empire of northern India. In 305 BC, Seleucus, one of the successors, marched to India to reclaim the territory; instead, he ceded the area to Chandragupta in return for 500 war elephants. These in turn played a pivotal role in the Battle of Ipsus, the result of which did much to settle the division of the Empire.
