The Balkan Wars 1912-1913 – Were two successive military conflicts that deprived the Ottoman Empire of all its remaining territory in Europe except part of Thrace and the city of Adrianople (Edirne). The second conflict erupted when the Balkan allies Serbia, Greece, and Bulgaria quarreled over the partitioning of their conquests. The result was a resumption of hostilities in 1913 between Bulgaria on the one hand and Serbia and Greece, which were joined by Romania, on the other.
The fuse to the First World War was lit in the Balkans where simmering hatreds exploded into violence. Like a string of firecrackers, these hatreds had been fuelled by attacks on the Turkish Ottoman Empire in the previous few years. From 1911-1912, Italy seized Libya. In 1912, the Balkan states united to drive Turkey out of Europe in the First Balkans War, and in the following year in the Second Balkans War, turned on each other in a division of the spoils which allowed Turkey to retain a foothold in Europe. This was a war of land campaigns, sea battles and amphibious operations in which the new military technology was first used. Submarine and aircraft attacked ships, aircraft made reconnaissance flights and bombed troops while even electronic warfare was used. It also saw mirror images of the events in the First World War; Bulgarians driven from Salonika where an Allied army would later be contained and Turkish troops held back in the Dardanelles, their guns driving off a naval task force.
