Amid the European alliances of 1914, Greece found itself in a quandary. It had a number of reasons for opposing the Central Powers. First, the unredeemed Greeks of the East were cause for opposing any alliance that included the Porte. Second, Bulgaria, still a rival for territory in Macedonia, had aligned itself with the Central Powers. Third, treaty obligations bound Greece to Serbia, which was in a territorial dispute with the AustroHungarian Empire over Bosnia. Finally, the Entente powers had earned Greek loyalty by supporting Greek national aspirations since the struggle for independence. On the other hand, Queen Sofia of Greece was the sister of Kaiser Wilhelm of Germany, and the German military establishment had considerable influence among Greek military leaders, many of whom had been trained in Germany. When World War I erupted in the summer of 1914, these interests came into direct conflict, and Greece was compelled to choose a side. http://greece.russiansabroad.com/country_page.aspx?page=59
