Hellenistic Period of Ancient Greece

The Hellenistic Period of Ancient Greece begins with the death of Alexander the Great in 323 B.C. and lasts until the the Roman Empire conquered the last of the Greek territories, signified by the final defeat of the Ptolemaic Kingdom at the Battle of Actium in 31 B.C. After Alexander the Great’s death, his generals split up his Empire into several territories or realms which ultimately resulted in the spread of Greek culture during the Hellenistic Period. The great centers of Greek culture became centered in the newer regions: Alexandria in Ptolemaic, Egypt and Antioch in Seleucid Syria.
