Excerpts from Books and Wikipedia
"The Macedonians under Alexander the Great ushered in the Hellenistic period with his conquest of Persia and Egypt. The Argeads ruled from 332 to 309 BC." [Wikipedia] "The Argead dynasty (Greek: Ἀργεάδαι, Argeádai) was an ancient Macedonian royal house of Dorian Greek provenance. They were the founders and the ruling dynasty of the kingdom of Macedon from about 700 to 310 BC." [Wikipedia] "The second Hellenistic dynasty, the Ptolemies ruled Egypt from 305 BC until Egypt became a province of Rome in 30 BC (whenever two dates overlap, that means there was a co-regency). The most famous member of this dynasty was Cleopatra VII, who in modern times is known simply as Cleopatra, and who had affairs with Mark Antony and Julius Caesar." Cleopatra ruled 51-30 BC.
