A Guide to the United States’ History of Recognition, Diplomatic, and Consular Relations, by Country, since 1776: Bulgaria


Bulgaria revolted against Ottoman Turkish rule in 1876. The Treaty of San Stefano, which ended the Russo-Turkish War of 1877-78, established a large Bulgarian state. The Treaty of Berlin (1878), however, established a smaller Bulgarian principality north of the Balkan Mountains. Its boundaries were not finalized until after World War I. Bulgaria became independent of the Ottoman Empire on October 5, 1908, after which its reigning Prince, Ferdinand of Saxe-Coburg, proclaimed himself Tsar.

U.S. Recognition of Bulgarian Independence, 1909.

Bulgaria declared its independence on October 5, 1908. The United States recognized Bulgaria on May 3, 1909, when Secretary of State Philander Knox instructed Chargé Norman Hutchinson to convey a message from President William H. Taft to Tsar Ferdinand, which offered the president’s congratulations “upon the admission of Bulgaria to the community of sovereign and independent States.”

Consular Presence

A Consular Agency was established in Sofia on January 12, 1912. It reported to the Consulate General in Bucharest. It became a Consulate General on February 22, 1915.

Diplomatic Relations

Establishment of Diplomatic Relations, 1903.

The first U.S. diplomatic representative in Bulgaria was Charles M. Dickinson, who was appointed Agent on April 24, 1901. He held the position until June 30, 1903. Dickinson served concurrently as Consul General at Constantinople, and there is no record that he ever presented credentials in Sofia.

John B. Jackson, who was Minister to Greece, Romania, and Serbia, was the first Diplomatic Agent to Bulgaria, and the first U.S. representative to present his credentials there, which he did on September 19, 1903. This date marks the establishment of diplomatic relations between Bulgaria and the United States. He was re-appointed in 1911 as Minister to Romania, Serbia, and Bulgaria. Later Diplomatic Agents to Bulgaria (1907-10) were also Ministers to Romania and Serbia. Only one of them, Horace G. Knowles (1907-09) presented his credentials in Bulgaria. Only after World War I was a U.S. representative commissioned solely to Bulgaria.

However, the United States still recognized the pre-war Bulgarian government. The U.S. Legation in Sofia was reopened on September 27, 1947, and Donald R. Heath presented his credentials on November 8 as U.S. Minister to Bulgaria.

Treaties and Agreements

Most-Favored-Nation Status, 1906.

Key Diplomatic Events

In 1876, Eugene Schuyler, U.S. Consul General in Constantinople, was sent to Bulgaria to investigate what would now be called a human rights issue: Turkish suppression of a Bulgarian revolt. He reported at length on “the Bulgarian Horrors,” and helped shift British policy away from unconditional support for the Ottoman Empire.
