Greece and the First World War
Wedged between the First World War’s warring parties, Greece was vital to supplying the isolated Serbia, but remained divided by pro-Entente and pro-German factions.

The raw facts of Greek involvement in the First World War belie the complexities and intrigue that went with it. It was not until July 1917 that Greece openly declared its hand and came out on the side of the Entente (Britain, France and Russia). In September 1918 it played a crucial part in the successful Macedonian campaign, which led to the collapse of Bulgaria, a fact that accelerated German surrender two months later. A period of prolonged neutrality meant that, in terms of manpower, Greece avoided the total calamity that befell other participants. But, nevertheless, the war led to political breakdown and to a bitterness and resentment, both internal and external, which has never been totally eradicated.
