Explanation:

It is called the Hellenistic period or Hellenism or Alexandrian period (by Alexander the Great) to a historical stage of antiquity whose chronological limits are marked by two important political events: the death of Alexander the Great (323 BC) and the death of the last Hellenistic sovereign, Cleopatra VII of Egypt, and her lover Marco Antonio, after their defeat in the battle of Actium (31 BC). This last event marked the rise of the Roman Empire in the Mediterranean Sea. The Hellenistic culture was characterized by the spread of the culture, spirit, values, science, and philosophy of ancient Greece throughout the Mediterranean Sea and the regions that were conquered by Alexander the Great. The Romans were among these cultures that were deeply influenced by Hellenistic culture, and with their eventual expansion, Greek cultural elements also spread throughout Europe, North Africa, and the Middle East.
