Ptolemy wasn’t an heir to ATG, he was one of his generals.
There are some scholars who say that Ptolemy was the illegitimate son of Philip II of Macedon through his concubine, Arsinoe. Macedonians regarded Ptolemy as Philip’s son. So Cleopatra, whose father was a Ptolemy descendant, was Macedonian/Greek and definitely not black.
“Ptolemy wasn’t an heir to ATG, he was one of his generals.”
yes he was one of his generals who was given part of his kingdom after Alexanders death - hence he was an heir to part of Alexanders kingdom (i think the kingdom was carved into three but not sure about that)
an heir doesnt have to be a be a blood relative my friend.
