Miniature Sheets no. 2 and 3: Fatherland Front Coalition 1st anniversary (1945):




(1) In 1944 the Soviet army was approaching Balkan and the pressure on Bulgaria increased. After first having declared Bulgaria as neutral, on August 25th the government demanded that all German troops had to leave Bulgaria. On September 5th the Bulgarian government terminated all diplomatic connections with Germany, and two days later declared war on Germany. The Soviet Union, however, had then already declared war on Bulgaria and the Soviet army invaded the country. On September 9th the Royal government was overthrown and replaced with a government of the Fatherland Front (Bulgarian political resistance movement during WW2) led by K. Georgiev. Following that date, large-scale political, economic and social changes were introduced to the country, with Bulgaria quitting the Axis and falling in the Soviet sphere of influence.

(2) Aleksandar Stamboliyski (1879 -1923) was the prime minister of Bulgaria from 1918 until 1923. Stamboliyski was a member of the Agrarian Union, a movement which was not allied to the monarchy, and edited their newspaper. Opposed to the country's participation in the Balkan War and its support for the Central Powers during World War I, he was court-martialed and sentenced to life in prison in 1915. He was a supporter of the idea of a Balkan federation.
In 1918, with the defeat of Bulgaria in the war, Tsar Ferdinand abdicated in favor of his son Tsar Boris III who released Stamboliyski from prison. He joined the government in January, 1919, and was appointed prime minister on October 14 of that year. On March 20, 1920, the Agrarian Union won national elections and Stamboliyski was confirmed as prime minister. During his term in office, Stamboliyski took the unpopular measures of complying with the terms of Bulgaria's surrender. Though popular with the peasants, this antagonized the middle class and military. Many considered him to be a virtual dictator. He was ousted in a military coup on June 9, 1923. He attempted to raise a rebellion against the new government, but was captured by the military, tortured and killed.

(3) The Monastery of Saint John of Rila, better known as the Rila Monastery is the largest and most famous Eastern Orthodox monastery in Bulgaria. It is situated in the northwestern Rila Mountains, 117 km south of the capital Sofia in the deep valley of the Rilska River at an elevation of 1,147 m above sea level. Founded in the 10th century, the Rila Monastery is regarded as one of Bulgaria's most important cultural, historical and architectural monuments. It is also a key tourist attraction in Bulgaria and Southeastern Europe as a whole. It is traditionally thought that the monastery was founded by the hermit St. John of Rila (Ivan Rilski), whose name it bears, during the rule of Tsar Peter I (927-968) and built by his students. The oldest buildings in the complex date from the 14th century when the monastery was reerected at its present place.

(4) On September 8th, 1946 a referendum decided by a 93 percent majority proclaimed Bulgaria a republic, and Tsar Simeon II and the queen mother were required to leave the country.
