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 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.
