In 1912 and 1913, Bulgaria fought two wars to try regain territories it felt were rightfully Bulgarian from its neighbors. In the First Balkan War (1912), Bulgaria allied itself with Serbia, Greece and Montenegro, and successfully took Thrace and Macedonia from Turkey. However, in the Second Balkan War (1913) Bulgaria quarreled with its former allies and went to war, eventually fighting against Serbia, Greece, Montenegro, Ottoman Turkey and Romania. Bulgaria lost most of Thrace to Greece and Turkey; the city of Silistra and province of Southern Dobrudzha to Romania, and most of Macedonia to Serbia. During both wars, the United States remained neutral.
