The retreat from Dobro Pole brought a soldier revolt that was crushed by German troops near Sofia. But the parties in power forced Ferdinand to abdicate at the end of September because they feared full-scale revolution and blamed the tsar for the country's chaotic state. Ferdinand's son Boris was named tsar, becoming Boris III. The immediate cause of social upheaval ended with the armistice, but shortages and discontent with the Bulgarian government continued. An ineffective coalition government ruled for the next year, then a general election was called. Meanwhile, Bulgaria was again left far short of the territorial goals for which it had declared war. In the Treaty of Neuilly-sur-Seine (November 1919), Thrace was awarded to Greece, depriving Bulgaria of access to the Aegean Sea. The newly formed Kingdom of the Serbs, Croats, and Slovenes took Macedonian territory adjoining its eastern border, and Southern Dobruja went to Romania (see fig. 7).

The treaty limited the postwar Bulgarian Army to a small volunteer force; Yugoslavia, Romania, and Greece were to receive reparations in industrial and agricultural goods; and the victorious Allies were to receive monetary reparations for the next thirty-seven years. On the other hand, the payment schedule was significantly improved in 1923, and Bulgaria's loss of 14,100 square kilometers was much less than the territorial losses of its wartime allies. Nationalist resentment and frustration grew even stronger because of this outcome, however, and Bulgaria remained close to Germany throughout the interwar period.
