Between September 2 and September 9, 1944, a rapid sequence of political changes, military maneuvers, and a Soviet declaration of war culminated in the takeover of the Bulgarian government by the Fatherland Front, an event that served as Bulgaria’s national holiday for about 40 years, according to historical accounts. The crisis unfolded as Sofia attempted to break away from Nazi Germany and secure an armistice with the Western Allies, only to face a Soviet invasion and a domestic coup.
The Background of Bulgaria and the Axis Alliance
Following Nazi Germany’s invasion of the Soviet Union on June 22, 1941, Bulgaria heldйна the unusual position of being a member of the Axis powers while maintaining diplomatic relations with the USSR and refusing to declare war on it, according to historical records. Tsar Boris III resisted German pressure to send Bulgarian troops to the Eastern Front, directing forces instead to occupation duties in Yugoslavia and Greece. Furthermore, Sofia evacuated its diplomatic representation from the Soviet capital to Kuybyshev, now known as Samara, just ahead of the Nazi assault on Moscow.
Relations deteriorated steadily over the years. Moscow accused Sofia of allowing Germany to use Bulgarian territory and facilities, and of supporting the communist resistance while suppressing the pro-Soviet Bulgarian Communist Party (BKP) and its partisan movement. By 1943-44, as Germany’s military position collapsed, Sofia sought to distance itself from Berlin. In August 1944, Bulgaria declared neutrality in the German-Soviet conflict and demanded the withdrawal of German forces.
The Communist Resistance and the Rise of the Fatherland Front
Until September 2, 1944, the Bulgarian Communist Party operated as an illegal, revolutionary opposition movement in open conflict with the government, according to historical sources. Following the 1941 German invasion of the USSR, communists organized armed resistance through partisan detachments, underground networks, and urban combat groups that launched sabotage operations against state authorities and German interests. The government responded with arrests, executions, and large-scale police and military operations, particularly throughout 1943 and 1944.
Beginning in 1942, communists emerged as the primary organizational force within the broader Fatherland Front, a political coalition aiming to oust the existing government and pull Bulgaria out of the Axis. Although the partisan movement expanded as Germany’s military fortunes waned, it had neither defeated the Bulgarian state nor captured control of most of the country prior to September 1944. By late August, following the success of the Soviet Third Ukrainian Front in the Jassy-Kishinev offensive and the Red Army’s approach, communists intensified their campaign to topple the government, remaining adversaries to the anti-German administration of Konstantin Muraviev when it took office.
Chronology of the Crisis: September 2 to September 9, 1944
On September 2, 1944, the cabinet of Ivan Bagryanov resigned, and Konstantin Muraviev formed a new government composed mainly of members of the legal anti-German opposition, offering participation to the Fatherland Front, which declined. The new administration sought an armistice with Great Britain and the United States, promised democratic reforms, and worked toward a definitive break with Germany, requiring German forces to leave or face disarmament.

On September 3, Muraviev’s government began dismantling repressive measures of the previous regime by releasing political prisoners, halting executions, and restoring political freedoms to convince Western allies and Moscow that Sofia had genuinely changed sides. The crisis turned military on September 4 as the government began disarming German troops on Bulgarian territory, while German forces attacked retreating Bulgarian units from Yugoslavia, including headquarters around Нишка баня. The Fatherland Front responded by organizing strikes and increasing pressure on Muraviev.
September 5 marked a critical turning point when Muraviev’s cabinet decided to sever ties with Germany and declare war on the Third Reich. However, War Minister Gen. Ivan Marinov argued that execution should be delayed so Bulgarian troops could withdraw safely from Macedonia and Yugoslavia. This delay proved catastrophic. At 19:00 hours on September 5, the Soviet Union declared war on Bulgaria despite Sofia never having fought against the USSR, while communist leadership simultaneously began concrete preparations to seize power.
On September 6, government authority eroded further as Fatherland Front activists, communist organizations, and partisan units escalated activities nationwide, highlighted by a strike of Sofia tramway workers. On September 7, Bulgaria severed diplomatic relations with Germany and its European allies—including Croatia, Slovakia, and the Italian Social Republic—while Muraviev’s government lifted restrictions on Bulgarian Jews, restored political parties, and dissolved the gendarmerie, the National Assembly, and fascist-linked organizations. Unrest and clashes with police, particularly among miners in Pernik, resulted in casualties.
On September 8, Bulgaria’s delayed declaration of war against Germany took effect, placing the country in the extraordinary position of being officially at war simultaneously with Germany, the USSR, Great Britain, and the United States. According to the chronology of the National Museum of Military History, advanced elements of the Soviet Third Ukrainian Front crossed the Romanian-Bulgarian border around 11:00 hours, prompting Muraviev to order the Bulgarian army not to resist the Red Army and to request an armistice. That same day, the Fatherland Front finalized its takeover plan, with Кимон Георгиев and other conspirators agreeing on a new cabinet roster.
Did You Know? Before the events of September 1944, Bulgaria maintained the unique diplomatic stance of participating as a member of the Axis powers while keeping diplomatic ties open with the Soviet Union and refusing to declare war on Moscow.
During the night of September 8 to September 9, military officers linked to the Fatherland Front seized the Ministry of War at around 02:15 hours on September 9, aided by a battalion from the 1st Engineering Regiment. Other forces occupied Radio Sofia, the General Post Office, and the government’s telephone communications center, arresting Muraviev’s ministers. Although a tank brigade in Горна баня stood ready to intervene, its deployment proved unnecessary because the coup met no organized resistance.
At 06:30 hours on September 9, Radio Sofia broadcast the new government’s proclamation, with Кимон Георгиев announcing that the Fatherland Front had taken power. The new cabinet included representatives from Zveno, the Bulgarian Workers’ Party (communists), agrarians, socialists, and independents. Although the coalition included multiple factions, communists held the organizational framework and Soviet backing that would subsequently enable them to dominate the regime.
Expert Insight: According to historical analysis of the period, the inclusion of non-communist figures like Кимон Георгиев—a former army officer and former prime minister with deep military connections—initially gave the new government a broader political and military character than a purely communist takeover, although the structural dominance of the communist party quickly followed.
