26 August 1944 - Under threat of the advancing Soviet front, Premier
Ivan Bagryanov’s government proclaims Bulgarian neutrality and orders German troops to withdraw. The Communist Party’s Central Committee immediately calls for an armed uprising to seize power. (On 30 Aug,
Stalin announced the
USSR would no longer recognize Bulgaria’s neutrality, raising the stakes.)
2 September 1944 - A new government of the Agrarian “Vrabcha 1” coalition is formed under Prime Minister
Konstantin Muraviev. It resumes peace talks with the
Allies and orders
German forces to leave Bulgaria, but the
Fatherland Front (dominated by Communists) withholds support and continues partisan operations. Soviet distrust grows as guerrilla actions persist.
5 September 1944 - The
Soviet Union officially declares war on Bulgaria (catching the Western Allies by surprise) and on that day Communist leaders begin planning a coup. The
Bulgarian Workers’ Party (Communists) and partisan command finalize a plan to overthrow Muraviev's government during the night of 8–9 September.
6-7 September 1944 - Mass unrest erupts nationwide in anticipation of change. Key examples include a general strike by
Pernik miners, a tramworkers’ strike in
Sofia, and general strikes in
Plovdiv and
Gabrovo. Partisan detachments flood over 170 localities by 8 September, freeing political prisoners in
Pleven,
Varna and
Sliven. Many demonstrations turn violent as FF-organized militias clash with police.
8 September 1944 - By this date Bulgaria has formally broken with the
Axis (declaring war on
Germany) but is simultaneously at war with
Britain, the
USA and the
USSR. Soviet
3rd Ukrainian Front forces cross into northeastern Bulgaria (
Varna,
Burgas, etc.) unopposed - on government orders the
Bulgarian Army offers no resistance. Fatherland Front militias and partisans by now control many regional governments.
Night of 8–9 September 1944 - In Sofia the
coup is launched. In the early hours (about 2:00 AM)
Zveno-affiliated officers and War Minister
General Ivan Marinov seize the War Ministry and other key installations. First Infantry Division and reserve schools obey Marinov's orders to join the coup. Within four hours the FF-aligned troops and partisan guerrillas control Sofia's government, police HQ and communication hubs.
9 September 1944 (morning) - At
6:25 AM Kimon Georgiev (leader of the
Zveno coup group, now
Fatherland Front premier) broadcasts a proclamation over Radio Sofia announcing that the
Fatherland Front has assumed power “in order to save the country”. Under orders of
NOVA partisan commander
Dobri Terpeshev all guerrilla units stream down from the mountains to occupy towns and villages. In
Sofia,
Plovdiv,
Pernik and other regions, remaining loyalist army and police forces either stand down or are defeated in skirmishes. By mid‐day the
Muraviev government is overthrown and a Fatherland Front coalition cabinet (Communists, Zveno, Agrarians, Social Democrats) is proclaimed.
Prime Minister Muraviev and the three royal Regents (
HRH Prince Kiril,
Bogdan Filov,
Nikola Mihov) are arrested. (The
BTA confirms the regents were immediately removed and new Soviet-backed regents installed.)
Kimon Georgiev is approved as Prime Minister, and Bulgaria nominally remains a monarchy under the
7‑year-old HRH Tsar Simeon II (albeit without real power).
9 September 1944 (evening) - Soviet-Bulgarian hostilities formally end. On the evening of the coup a high-level Bulgarian delegation (General Stanchev and others) meets
Marshal Tolbukhin, commander of the
3rd Ukrainian Front. Late that night (about 10:00 PM) Stalin orders Soviet forces to halt all offensive operations in Bulgaria. Effectively, Bulgarian troops have ceased fighting the Soviets (orders forbade any resistance). The swift, bloodless victory of the Fatherland Front over pro-German elements sends a clear signal that the USSR is now the dominant power in Bulgarian affairs.
10 September 1944 - The new government moves quickly to dismantle former regime institutions. The old Interior Ministry police are abolished; a new People's Militia of former partisans is organized to maintain order. Over 8,130 political prisoners are released from jails, and the concentration camps of the old regime (e.g. Gonda voda, Krasto pole) are closed. All fascist organizations and publications are banned. Local Antifascist Committees (FCs) take charge in towns and villages. The Fatherland Front cabinet begins appointing loyal officers to command the army and police.
12 September 1944 - Pockets of military resistance are overcome. In the
Pernik area and at
Shumen insurgent forces rout remaining loyalist units. At
Haskovo partisans storm the large artillery barracks on 12 Sept (suffering heavy losses) to eliminate a final island of government control. That same day the new regime issues a legal decree authorizing the arrest of all wartime cabinet ministers (1941–44), members of the old parliament and high-ranking officers. This official decree gives retroactive legitimacy to mass arrests that are now sweeping the country - in the following weeks thousands (civil servants, landowners, intellectuals, Social Democrats, Agrarians and others) are detained by the militia and FC cadres on flimsy charges.
17 September 1944 - Prime Minister Georgiev publicly outlines the Fatherland Front's program. At a rally in Sofia's Palace of Justice he promises democratic reforms, anti-fascist justice and sweeping social change. (Zveno, now an official party again, holds a national conference on 1 Oct, but its role is increasingly overshadowed by the Communists.)
10 October 1944 - Under Soviet pressure, the Fatherland Front orders the Bulgarian Army to withdraw from territories in Greek and Yugoslav Macedonia and Thrace (occupied since 1941). This fulfills a key Allied demand and isolates Bulgarian forces to the pre-1941 border.
28 October 1944 - Bulgaria signs the
Moscow Armistice with the Allied Powers. Foreign Minister Petko Staynov, Ministers
Nikola Petkov,
Dobri Terpeshev and
Petko Stoyanov sign on behalf of Bulgaria (represented by Gen. Gammell for the Allies and
Marshal Tolbukhin for the USSR). The armistice terms acknowledge that Bulgaria “ceased hostilities with the USSR on September 9” and agrees to disarm remaining German forces. Bulgaria commits to cede the care of its troops to the Allied (Soviet) command and to withdraw from Greek/Yugoslav territory. Crucially, Bulgaria must tolerate Soviet occupation of its territory and submit to an Allied Control Commission (dominated by the USSR). In effect, Bulgaria is now firmly in the Soviet camp and must immediately “make available” its army for Soviet-directed operations against Germany.
3 December 1944 - A sharp political clash occurs over remnants of the old military. Acting on a proposal by nationalist General
Damyan Velchev, the Council of Ministers decrees that officers charged under the forthcoming
People's Court law may be sent to the front; if they “show bravery,” they can earn discharge. This measure (intended to rally the armed forces by mercy) is immediately denounced by the Communists as “counter-revolutionary.”
6 December 1944 - The Soviet Allied Control Commission intervenes. Marshal
Sergey Biryuzov, Soviet head of the commission, insists that the 3 Dec decree be revoked. Reluctantly, the Georgiev government cancels its own decree, fearing a breakdown in relations with Moscow. In the aftermath, Communists take direct control of the military and security apparatus. Communist cadres assume top posts in the General Staff and DS intelligence, while Dr. Georgiev (as War Minister) and Col. General
Damyan Velchev (Defense) are sidelined.
December 1944 - The new regime formalizes its system of reprisals. The Council of Ministers issues a decree establishing the
People’s Court (Naroden sad) - a special tribunal to try “fascist” officials and wartime collaborators. (Hearings will begin in early 1945.) This paves the way for a nationwide purge. During these months thousands of former officials are tried, and many are summarily executed or sentenced to death. In parallel, extrajudicial killings of “class enemies” surge, particularly in Sofia, where Communist security forces eliminate real and imagined opponents. In short order, virtually all political opposition outside the Fatherland Front is crushed and monarchy is rendered obsolete. (King Simeon II remains a child ruler in theory, but in practice the monarchy's regents are deposed and Bulgarian governance is now guided by Soviet-backed communist leadership.) ==Coup d'état==
