Another crisis took place in the Balkans in 1908 over the annexation by Austria-Hungary of Bosnia and Herzegovina. Because one form of pan-Slavism was a Pan-Serbian or Greater Serbia movement in Serbia, which had as one of its objects the acquisition by Serbia of the southern part of Bosnia, the Serbs threatened war against Austria. War was avoided only because Serbia could not fight without Russian support, and Russia at the time was unprepared for war. A third crisis, again in Morocco, occurred in 1911 when the German government sent a warship to Agadir in protest against French efforts to secure supremacy in Morocco. After threats of war on both sides, the matter was settled by a colonial compromise between France and Germany in November 1911. Taking advantage of the preoccupation of the Great Powers with the Moroccan question, Italy declared war on Turkey in 1911, hoping to annex the Tripoli region of northern Africa. Because Germany's policy of Drang nach Osten ("drive towards the East") obliged it to cultivate friendship with Turkey, the Italian attack had the effect of weakening the Triple Alliance and encouraging its enemies. The Balkan Wars of 1912-1913 resulted in an increased desire on the part of Serbia to obtain the parts of Austria-Hungary inhabited by Slavic peoples, strengthened Austro-Hungarian suspicion of Serbia, and left Bulgaria and Turkey, both defeated in the wars, with a desire for revenge. Germany, disappointed because Turkey had been deprived of its European territory by the Balkan Wars, increased the size of its army. France responded by increasing peacetime military service from two to three years. Following the example of these nations, all the others of Europe in 1913 and 1914 spent huge sums for military preparedness.
