The Bulgarian coup d'état of 1923, also known as the 9 June coup d'état (Bulgarian language: Деветоюнски преврат , Devetoyunski prevrat), was a coup d'état in Bulgaria implemented by armed forces under General Ivan Valkov's Military Union on the eve of 9 June 1923. Hestitantly legitimated by a decree of Tsar Boris III of Bulgaria, it overthrew the government of the Bulgarian Agrarian National Union headed by Aleksandar Stamboliyski and replaced it with one under Aleksandar Tsankov.


The Bulgarian army, defeated in World War I, was limited in size of 20,000 men by the Treaty of Neuilly-sur-Seine. A shadow of its former glory, the army retained weapons hidden away for better times.[1] In 1919 a group of officers led by Generals Ivan Valkov and Velizar Lazarov - and joined by Kimon Georgiev and Damyan Velchev - formed the Military Union. This organization grew over the next couple of years to effectively command the army.

After the war Aleksandar Stamboliyski was released imprisoned in an effort to quell the civil unrest against the wartime government and Tsar Ferdinand. The result had mixed success: Ferdinand abdicated in favor of his son, Boris III, and Stamboliyski became Prime Minister in 1919. His new agrarian government brought about reforms that, although may have been popular with the farmers who comprised over 80% of the population of Bulgaria (in 1920), were unpopular amongst the upper-middle class parties.[2] Even more dangerous for Stamboliyski's government was that the armed forces was not allowed to nominate the Minister of Defence and had no representation in cabinet since the end of the war. This meant that Stamboliyski's government had no support from the army. As the power of the Military Union grew the civilian government was in danger of being overthrown by an unloyal army.[1]

To the dismay of opposition parties and Tsar Boris III, the BANU and Communist Party polled a combined total of 59% of the votes in the 1920 elections. The middle-class, business men and aristocrats worried for their interests that, for the first time, were being seriously challenged by the peasants. As the agrarian government grew more and more autocratic, even sidelining the tsar. A group of the old bourgeois parties ran together in the April 1923 elections as the Constitutional Bloc but only won 17 seats. Fraud and the newly effective first-past-the-post voting system were the culprits; although the BANU was still relatively popular amongst the countrymen.[2] In 1922 after gaining the approval by a plebiscite, the government began trying and imprisoning leaders of opposition parties for their roles in previous wars. In the face of repression, the bourgeois parties decided that the overthrow of the government was a necessity to their survival.

Based in the Macedonian region of Bulgaria the insurgent Internal Macedonian Revolutionary Organization carried out attacks against Greece and the Kingdom of Yugoslavia. On March 23, 1923 Stamboliyski signed the Treaty of Niš pledging to suppress their activities. The organization, until now at peace with the government, now began plotting against it.


Opposition parties met with leaders of the Military Union to prepare for the coup. The Military Union, wanting to give an appearance of legality to the ouster of Stamboliyski, needed a civilian government to hand over power to.[1]

The Coup

On the morning of June 9, 1923, before dawn, the order was given for the garrisons in Sofia to block roads, cut telephone lines, and take control of key objectives suck as police stations, post offices and train stations.[3] After three hours, the coup was successful. By 5a.m. a new government led by Aleksandar Tsankov installed in Sofia.[1] The next morning the leaders of the coup meet with Tsar Boris at his palace in Vrana. After a six hour meeting they convinced him to sign a decree legitimizing the new cabinet, on the condition the new government include agrarians and avoid repression.[3] Both of these conditions were ignored.

Aleksandar Stamboliyski was away from the capital on the day of the coup. He was arrested five days later and handed over to Macedonian insurgents in his home town of Slavovitsa who brutally tortured him for hours, and cut off his hand, before finally murdering him.[4]


Despite the initial success, the new government was still in danger. In several places, the coup met with the opposition of agrarian activists and individual communist volunteers, an event known in Bulgarian historiography as the June Uprising. The uprising was largely unorganized in its essence, lacking a common leadership - after the death of Stamboliyski - and a nation-wide radius of action. Despite large-scale activity by the rebels around Pleven (which they managed to capture), Pazardzhik and Shumen, it was quickly crushed by the new government. Crucial was the inactivity of the Bulgarian Communist Party.

Unlike the agrarians, the Communists Party of Bulgaria (member of Comintern) had a strong military organization. It was well supplied with arms by BCP followers within the barracks and, unlike the party of the agrarians, was already in the grip of the notorious communist iron discipline.[5] Its position could have decided between the success or failure of the coup. In a move that would prove fatal to both the agrarians and later themselves, the communists did not take part in the June Uprising. Its leadership regarded both the uprising and the coup as "struggle for power between the urban and rural bourgeoisie" and as a replacement of one military dictatorship - that of the rural bourgeoisie and their 'posse comitatus', with another - that of the urban upper middle class.[5] The party's stance of neutrality allowed the new government to crush the rebels and consolidate its power.

Arrested rebels in Vratsa

Under pressure from the Comintern, who condemned their inactivity, the Communist Party made preparations in August for an uprising the following month. This short time frame did not allow for nation-wide organization. Furthermore the new government was made aware of the impending rebellion and subjected the communists to mass arrests. This crippling pre-emptive blow crippled the rebels and who finalized plans for an uprising on the eve of September 23. The insurrection was put down by the army. Thousands of rebels were killed without charge or trial.[5]

This marked the debut of Aleksandar Tsankov's reign of "white terror", prompting the future bombing of the St Nedelya Church, prompting, in turn, martial law and an intensification of the terror.
