Tsar Boris III of Bulgaria

 

Boris III (Bulgarian: Борѝс III; 30 January [O.S. 18 January] 1894 – 28 August 1943), originally Boris Klemens Robert Maria Pius Ludwig Stanislaus Xaver (Boris Clement Robert Mary Pius Louis Stanislaus Xavier)^[a], was the Tsar of the Kingdom of Bulgaria from 1918 until his death in 1943.

The eldest son of Ferdinand I, Boris assumed the throne upon the abdication of his father in the wake of Bulgaria's defeat in World War I. Under the 1919 Treaty of Neuilly, Bulgaria was forced to, amongst other things, cede various territories, pay crippling war reparations, and greatly reduce the size of its military. That same year, Aleksandar Stamboliyski of the agrarian Bulgarian Agrarian National Union became prime minister. After Stamboliyski was overthrown in a coup in 1923, Boris recognized the new government of Aleksandar Tsankov, who harshly suppressed the Bulgarian Communist Party and led the nation through a brief border war with Greece. Tsankov was removed from power in 1926, and a series of prime ministers followed until 1934, when the corporatist Zveno (Bulgarian: Звено) movement staged a coup and outlawed all political parties. Boris opposed the Zveno government and overthrew them in 1935, eventually installing Georgi Kyoseivanov as prime minister. For the remainder of his reign, Boris would rule as a de facto absolute monarch, with his prime ministers largely submitting to his will.

Following the outbreak of World War II, Bulgaria initially remained neutral. In 1940, Bogdan Filov replaced Kyoseivanov as prime minister, becoming the last prime minister to serve under Boris. Later that year, with the support of Nazi Germany, Bulgaria received the region of Southern Dobrudja from Romania as part of the Treaty of Craiova. In January 1941, Boris approved the anti-Semitic Law for Protection of the Nation, which denied citizenship to Bulgarian Jews and placed numerous restrictions upon them. In March, Bulgaria joined the Axis. In exchange, Bulgaria received large portions of Macedonia and Thrace, both of which were key targets of Bulgarian irredentism. Boris refused to participate in the German invasion of the Soviet Union and largely resisted German attempts to deport Bulgarian Jews as part of the Holocaust. In 1942, Zveno, the Agrarian National Union, the Bulgarian Communist Party, and various other far-left groups united to form a resistance movement known as the Fatherland Front, which would later go on to overthrow the government in 1944. In August 1943, shortly after returning from a visit to Germany, Boris died at the age of 49. His six-year-old son, Simeon II, succeeded him as tsar.
