===Second Balkan War===
{{main|Second Balkan War}}
The peace settlement of the First Balkan War proved unsatisfactory for both Serbia and Bulgaria. Serbia refused to cede a part of the territories in Macedonia, which it occupied and promised to give to Bulgaria according to a secret agreement. Serbia, on its side, was not satisfied with the independence of Albania and sought a secret alliance with Greece. Armed skirmishes between Serbian and Bulgarian troops occurred.

On 16 June 1913, just a few months after the end of the first war, the Bulgarian government ordered an attack on Serbian and Greek positions in Macedonia, without declaring war. Almost all of Bulgaria's 500,000-man standing army was positioned against these two countries, on two fronts—western and southern—while the borders with Romania and the [[Ottoman Empire]] were left almost unguarded. Montenegro sent a 12,000-strong force to assist the Serbs. Exhausted from the previous war, which took the highest toll on Bulgaria, the Bulgarian army soon turned to the defensive. Romania attacked from the north and northeast and the Ottoman Empire also intervened in [[Thrace]]. Allied numerical superiority was almost 2:1. After a month and two days of fighting, the war ended as a moral disaster for Bulgaria, and at the same time its economy was ruined and its military demoralised.
