Greece, like Bulgaria, initially maintained neutrality, but as the war continued, both warring camps began wooing the two countries. At this point the first rifts appeared among the Greek leadership: Prime Minister Eleftherios Venizelos, at the helm since 1910 of a modernising government looking towards the British and French models, supported entry in the war on the side of the Entente, while King Constantine I, who had been educated in Germany, married to Kaiser Wilhelm II's sister and a deep admirer of Prussian militarism, anticipated a German victory. Aware that Greece was vulnerable to the British Fleet, he advocated a course of neutrality.
