Question

is Ptolemy the person who overthrew Egypt and if so who was he the general of?

Answer 1

Perdiccas appointed Ptolemy, one of Alexander's closest companions, to be satrap of Egypt. Ptolemy ruled Egypt from 323 BC, nominally in the name of the joint kings Philip III and Alexander IV. However, as Alexander the Great's empire disintegrated, Ptolemy soon established himself as ruler in his own right.
