Seleucus now held the whole of Alexander's conquests except Egypt and moved to take possession of Macedonia and Thrace.
He intended to leave Asia to Antiochus and content himself for the remainder of his days with the Macedonian kingdom in its old limits.
He had, however, hardly crossed into the Thracian Chersonese when he was assassinated by Ptolemy Keraunos near Lysimachia in September (281 BC).

It seems certain that after taking Macedonia and Thracia, Seleucus would have tried to conquer Greece.
He had already prepared this campaign using the numerous gifts presented to him.
He was also nominated an honorary citizen of Athens.

Antiochus founded the cult of his father.
A cult of personality formed around the later members of the Seleucid dynasty and Seleucus was later worshipped as a son of Zeus Nikator.
One inscription found in Ilion (i.e., Troy) advises priests to sacrifice to Apollo, the ancestor of Antiochus' family.
Several anecdotes of Seleucus' life became popular in the classical world.
