This map provides a snapshot of the Hellenistic World in 240 BCE, roughly a century after the death of Alexander the Great. It depicts the major successor states (the Diadochi) and the emerging independent powers that defined the eastern Mediterranean and Near East during this era.
The Primary Hellenistic Kingdoms
The territory is divided among four main dynasties, each originating from Alexander’s generals.
| Kingdom / Dynasty | Color Key | Core Regions | Key Cities |
| Seleucid Empire | Blue | Mesopotamia, Persia, Syria, Asia Minor | Seleukeia, Antioch, Babylon, Susa |
| Ptolemaic Kingdom | Yellow | Egypt, Cyrenaica, Levant coast, Cyprus | Alexandria, Memphis, Thebes, Tyre |
| Antigonid Dynasty | Green | Macedonia and parts of Greece | Pella, Thessalonike, Corinth |
| Attalid Dynasty | Pink | Northwest Asia Minor | Pergamon |
Regional Geography & Power Centers
-
The Seleucid Heartland: This was the largest successor state, stretching from the Mediterranean Sea in the west to the borders of India in the east.
-
The Ptolemaic “Nile State”: Centered on the Nile River, this kingdom also controlled strategic maritime points like Cyprus and the southern coast of Asia Minor to protect its interests in the Mediterranean.
-
The Greek Fragment: Greece and Macedonia (Antigonid) remained the cultural heartland but were politically fragmented compared to the vast eastern empires.
-
Independent Entities: Small “Independent Greek” city-states and regions (white) are scattered throughout, including Rhodes, Byzantium, and parts of the Black Sea coast.
-
Eastern Neighbors: To the far east and north, we see emerging or separate powers like the Mauryas (India), Bactria (under Diodotos I), and Parthia (under Arsakes I).
Key Observations of the Era
-
The “Syrian Wars” Arena: The area around Damascus and Jerusalem (Coere-Syria) is shown as a borderland between the Seleucids and Ptolemies, a region that was the site of frequent conflict.
-
Fragmentation in the East: You can see dashed lines indicating the loss of control in the east, where the Bactrian and Parthian kingdoms are breaking away from the Seleucid Empire.
-
Alexander’s Legacy: The map is dotted with “Alexandrias” (such as Alexandria in Egypt and Alexandria in the Kabul valley), illustrating the lasting impact of Alexander’s city-founding and the spread of Greek culture.
