If related businesses are added, the figure jumps to $23.7 billion, employs about 392,000 people (14% of the workforce), and shipping receipts are about 1/3 of the nation's trade deficit.
The Greeks have been a maritime nation since antiquity, as the mountainous landscape of the mainland, and the limited farming area and the extended coastline of Greece led people to shipping.
The geographical position of the region on the crossroads of ancient sea lanes in the eastern Mediterranean, the multiplicity of islands and the proximity to other advanced civilizations helped shape the maritime nature of the Greek nation at an early stage.
[8] The Greeks soon came to dominate the maritime trade in the region, gradually expanding it along the shores of the Mediterranean to Egypt, Phoenicia, Asia Minor, the Black Sea, and establishing colonies.
They expanded their shipping activities and trade towards western Europe in the 16th century, taking advantage from the rapidly increasing need for grain.
During the 18th century, the consolidation of political and economic power at the hands of the Phanariotes in Constantinople helped further expansion of the Greek maritime activity into the rest of Europe.
In addition, the Aegean Islands were heavily active in shipping, where traditionally the inhabitants occupied with maritime commerce, especially Hydra, Spetses, Andros, Syros, Chios, Kasos, Psara and Mykonos.
The growth of the Greek merchant fleet gave confidence and success to them, while their contact with the western peoples awakened their national consciousness and made them feel free.
[9] In the wake of the nineteenth century diaspora the Chiot families were well positioned to take advantage of the commercial opportunities across Europe after the Napoleonic Wars.
Accompanying these Greek-run fleets were local expatriate communities of workmen and agent-translators who managed the unfamiliar customs and bureaucracy in foreign ports.
The Second World War saw those Greek shipping companies operating in the Allied areas, place their fleets under control of the British Merchant Marine, and suffer the same depredations and difficulties.
