The results were first hailed as a great achievement in peacemaking and stabilisation. However, most of the participants were not fully satisfied, and grievances regarding the results festered until they exploded into world war in 1914. Serbia, Bulgaria and Greece made gains, but far less than they thought they deserved. The Ottoman Empire called at the time the "sick man of Europe", was humiliated and significantly weakened, rendering it more liable to domestic unrest and more vulnerable to attack. Although Russia had been victorious in the war that occasioned the conference, it was humiliated at Berlin, and resented its treatment. Austria gained a great deal of territory, which angered the South Slavs, and led to decades of tensions in Bosnia and Herzegovina. Bismarck became the target of hatred of Russian nationalists and Pan-Slavists, and found that he had tied Germany too closely to Austria in the Balkans.
