Macedonian frontThe Macedonian front, also known as the Salonica front (after Thessaloniki), was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the autumn of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and with insufficient force to prevent the fall of Serbia and was complicated by the internal political crisis in Greece (the National Schism).
Bulgaria during World War IThe Kingdom of Bulgaria participated in World War I on the side of the Central Powers from 14 October 1915, when the country declared war on Serbia, until 30 September 1918, when the Armistice of Salonica came into effect. After the Balkan wars of 1912 and 1913, Bulgaria was diplomatically isolated, surrounded by hostile neighbors and deprived of Great Power support. Negative sentiment grew particularly in France and Russia, whose officials blamed Bulgaria for the dissolution of the Balkan League, an alliance of Balkan states directed against the Ottoman Empire.
Serbian campaignThe Serbian campaign was a series of military expeditions launched in 1914 and 1915 by the Central Powers against the Kingdom of Serbia during the First World War. The first campaign began after Austria-Hungary declared war on Serbia on 28 July 1914. The campaign, euphemistically dubbed "punitive expedition" (Strafexpedition) by the Austro-Hungarian leadership, was under the command of Austrian General Oskar Potiorek. It ended after three unsuccessful Austro-Hungarian invasion attempts were repelled by the Serbians and their Montenegrin allies.
Ferdinand I of BulgariaFerdinand (Фердинанд I; 26 February 1861 – 10 September 1948), born Ferdinand Maximilian Karl Leopold Maria of Saxe-Coburg and Gotha (Фердинанд Максимилиан Карл Леополд Мария Сакс-Кобург и Гота), was the second monarch of the Third Bulgarian State, firstly as ruling prince (knyaz) from 1887 to 1908, and later as king (tsar) from 1908 until his abdication in 1918. Under his rule Bulgaria entered the First World War on the side of the Central Powers in 1915.
National SchismThe National Schism (Ethnikós Dichasmós), also sometimes called The Great Division, was a series of disagreements between King Constantine I and Prime Minister Eleftherios Venizelos regarding the foreign policy of Greece in the period of 1910–1922 of which the tipping point was whether Greece should enter World War I. Venizelos was in support of the Allies and wanted Greece to join the war on their side, while the pro-German King wanted Greece to remain neutral, which would favor the plans of the Central Powers.
Constantine I of GreeceConstantine I (Κωνσταντίνος Αʹ, Konstantínos I; – 11 January 1923) was King of Greece from 18 March 1913 to 11 June 1917 and from 19 December 1920 to 27 September 1922. He was commander-in-chief of the Hellenic Army during the unsuccessful Greco-Turkish War of 1897 and led the Greek forces during the successful Balkan Wars of 1912–1913, in which Greece expanded to include Thessaloniki, doubling in area and population. He succeeded to the throne of Greece on 18 March 1913, following his father's assassination.
