Greece has been occupied and ruled by foreign powers throughout history, but it was never formally a colony in the modern sense (i.e., a territory settled and administered by a distant imperial power for resource extraction).
| Power | Period | Nature |
|---|---|---|
| Macedon | 338–146 BCE | Hellenistic hegemony (Greek) |
| Roman Republic/Empire | 146 BCE – 330 CE | Provincial integration (Achaea, Macedonia) |
| Byzantine Empire | 330–1204, 1261–1453 | Continuation of Roman rule (Greek-centered) |
| Latin Crusader States | 1204–1261 | Feudal duchies (Athens, Naxos, Achaea) |
| Ottoman Empire | 1453–1821/1830 | Imperial province (Rum Eyalet); millet system |
| Venetian/Genoese | 13th–18th c. | Colonial outposts (Crete, Cyclades, Ionian) |
| British | 1815–1864 | Protectorate (Ionian Islands) |
| Nazi Germany / Italy / Bulgaria | 1941–1944 | Military occupation (tripartite) |
Ancient Greece founded colonies across the Mediterranean and Black Sea (Marseille, Naples, Syracuse, Byzantium, Odessa, etc.) — but Greece itself was the metropole, not the colony.
Modern Greece's sovereign history: 1830 (recognition) → present, with territorial expansions (1864 Ionian, 1881 Thessaly, 1913 Macedonia/Crete, 1919 Western Thrace, 1947 Dodecanese).
