In the First Balkan War of 1912–13, the Ottoman Empire had lost its Balkan possessions to Christian uprisings, intensifying fears in the Turkish homeland that the Empire's increasingly restive Armenian Christian minority—with the assistance or encouragement of Western governments—might also attempt to establish an independent state, resulting in the breakup of Turkey itself.[5][6] As a result of the wars, at least half a million Muslim Ottomans from the former Balkan possessions of the Empire sought refuge in Turkey,[7] sparking a desire for revenge among many Turks.[8] Distrust and suspicion of Armenians reached a peak following the outbreak of World War I, when a successful advance of Russian troops across the Turkish border into the heavily Armenian-populated vilayet of Van in early 1915 was blamed on Armenian disloyalty, leading the Turkish government to adopt a set of extreme measures which would culminate in the Armenian genocide.[6]
