The Bosnian Crisis - In 1908, Austria-Hungary took over Bosnia. This angered Serbians who felt the province should be theirs. Serbia threatened Austria-Hungary with war, Russia, allied to Serbia, mobilized its forces. Germany, allied to Austria-Hungary mobilized its forces and prepared to threaten Russia. War was avoided when Russia backed down. In 1911 and 1912 there was war in the Balkans when the Balkan states drove Turkey out of the area. The states then fought each other over which area should belong to which state. Austria-Hungary intervened and forced Serbia to give up land. Tension between Serbia and Austria-Hungary was high.
