The 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 while lacking the support of any great power. 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.
