Events in Bulgaria were strongly influenced by the Russian Revolution of February 1917, which stirred anti-monarchist and anti-war sentiment. In September 1918, there was a mutiny in the Bulgarian army, the so-called Vladaisko uprising and the combined forces of the Serbs, British, French and Greeks broke through Bulgarian lines on the Salonika front. Despite opposition from King Ferdinand, The Bulgarian Government of Prime Minister Malinov approached American diplomats about a possible withdrawal from the War, accepting the principals laid by President Wilson. From Sofia, Consul Murphy cabled to Washington, "Bulgaria accepts with good will the proposal that the President should be the arbiter of the Balkans." However, before the United States could take part in the negotiations, the Malinov government fell and was replaced by a government led by Agrarian Party leader Alexander Stambolyski. Stambolyski forced King Ferdinand to abdicate in favor of his son, Boris III, and signed an armistice with the Entente Powers.
