Perhaps many of you will wonder what exactly happened on September 23 and how and when this date became a holiday of the Bulgarian People's Army. The first signal answer is "nothing concrete", because September 23 is not a date associated with a major and specific event in Bulgarian history. But at the same time it is not so.
On September 22, 1908 the Independence of Bulgaria was declared, in a new style the date should be October 5, but to this day we celebrate the national holiday in the old style. So September 23 makes sense, although it is not exactly tied to the People's Army.
Another interesting year is September 23, 1948. For the second time Bulgaria applied to join the UN, our country joined in 1955.
Four years earlier, on September 23, 1944, the Children's and Youth Organization was established at the Workers' Youth Union, later called the Dimitrov Pioneer Organization "Septemvriyche".
So far, however, we do not have a clear answer as to why this date was chosen. September 23 has been designated a holiday of the Bulgarian People's Army by Decree № P-129 of the Council of Ministers of 1953. The holiday is celebrated for 38 years, when in 1993 the old date was "returned" - May 6, which was celebrated from 1926 to 1953 and was called the Feast of the Military Order "For Courage".
On this propaganda poster we see the praise of the People's Army holiday. As it has become clear so far, this is one of the few days that is not tied to a specific political event. The poster has technical notes that indicate its size and instructions for printing. It was printed in DVI (State Military Publishing House) in a circulation of 5,000 copies. The style of the image is typical of the late 50s of last century. The building that can be seen behind the two images of the soldiers is the Party House - the headquarters of the Central Committee of the Bulgarian Communist Party, which we know today as the building of the National Assembly. In fact, the building was built in the period 1948-1954.
