Imperial Europe (31 July 1913)

Historical Map of Europe

Bulgaria had gained much territory in the war against the Ottomans, but less than what it had been promised. In June 1913, exactly one month after peace had been signed, it attacked Serbia for more land. However, in the war that followed, the Greeks, Montenegrins, Romanians, and Ottoman Turks sided with the Serbs, and Bulgaria ended up defeated on all sides.
