The Bosnian Crisis (6 oct 1908 año – 1 mar 1909 año)

Descripción:

The Bosnian Crisis began in October 1908 when Austria-Hungary formally annexed Bosnia and Herzegovina, which it had been administering since 1878. The crisis ended in March 1909 after intense diplomatic pressure, particularly from Germany, forced Russia and Serbia to accept the annexation. The crisis significantly heightened tensions in the Balkans and between the Great Powers, setting the stage for further conflict leading up to World War I.
