Internally, the country was in relatively good condition during the early stages of the war. The economy, based primarily on active trade with the Germans, was booming. The Bulgarian people perceived the fighting as essentially a "paper war" and were generally apathetic regarding their role in the war. There was little suffering within Bulgarian boundaries and little expression of hatred toward Bulgaria's ostensible enemies. Despite Bulgaria's alliance with the Nazis and Fascists, within the country Jews were for the most part protected rather than persecuted.
By 1943, however, the war began to change for the Bulgarians. Slowly the Allies began to turn back German power. At this time Bulgaria was hit frequently by British and United States air raids. Because of Bulgaria's strategic significance and its declaration of war, albeit symbolic, against Great Britain and the United States, Sofia and other major Bulgarian cities became targets for American and British bombers. Sofia was reduced to little more than rubble at one point, and over 30,000 casualties were suffered by the Bulgarians.
In 1943 Boris died and was succeeded by his six-year-old son, Simeon. In fact, however, a three-man regency retained power, with Ivan Bagrianov as premier. The regency was less actively pro-Axis in orientation than was the late king; with its coming to power, thousands of political prisoners were released from jail, and all persecution of Jews was terminated.
By 1944, when Germany and its allies were clearly losing the war, the Bulgarian leaders sought to reverse the earlier decision of the king and to seek peace with the Allies as well as with the Greek and Yugoslav governments-in-exile. Despite sub rosa attempts to release itself from agreements with the Axis, Bulgaria was unable to extricate itself from the alliance. On August 22, 1944, the Bulgarian government publicly announced that it was ready for a peace agreement with the Allies.
The war was ended for Bulgaria when, on September 4, 1944, the Soviets, after taking over Romania, entered Bulgaria. The exact sequence of events has been interpreted differently by various historians. There are, however, two major interpretations. One suggests that, once the Soviets had occupied Romania and declared war on Bulgaria, Bulgaria--under a hastily formed anti-Axis coalition government--immediately quit the pact with the Axis and declared war on its former ally, Germany. The other interpretation posits the theory that, on August 26, the Bulgarian government had declared itself neutral, thus withdrawing from the war. At this time it ordered German troops on its soil to disarm. When Soviet troops arrived in Bulgaria, they found this so-called neutrality unacceptable and insisted on a Bulgarian declaration of war against Germany. This declaration was promptly carried out on the eve of the day that it was requested.
