was facing increasing nationalist pressure from its multinational populace. As Europe's third largest state, the Austro-Hungarian monarchy was hardly homogeneous; comprising over fifty million people and eleven nationalities, the Empire was a conglomeration of a number of diverse cultures, languages, and peoples. Specifically, the South Slavic people of Austria-Hungary desired to amalgamate with Serbia in an effort to officially solidify their shared cultural heritage. Over seven million South Slavs lived inside the Empire, while three million lived outside it. With the growing emergence of nationalism in the twentieth century, unity of all South Slavs looked promising. This tension is exemplified by Conrad von Hötzendorf's letter to Franz Ferdinand: The unification of the South Slav race is one of the powerful national movements which can neither be ignored nor kept down. The question can only be, whether unification will take place within the boundaries of the Monarchy – that is at the expense of Serbia's independence – or under Serbia's leadership at the expense of the Monarchy. The cost to the Monarchy would be the loss of its South Slav provinces and thus of almost its entire coastline. The loss of territory and prestige would relegate the Monarchy to the status of a small power. The annexation of Bosnia-Herzegovina in 1908 by Austrian foreign minister Baron von Aehrenthal in an effort to assert domination over the Balkans inflamed Slavic nationalism and angered Serbia. Bosnia-Herzegovina became a "rallying cry" for South Slavs, with hostilities between Austria-Hungary and Serbia steadily increasing. The situation was ripe for conflict, and when the Serbian nationalist Gavrilo Princip assassinated Austrian imperial heir, Franz Ferdinand, these longstanding hostilities culminated into an all-out war. The Allied Powers wholeheartedly supported the Slavs' nationalistic fight. George Macaulay Trevelyan, a British historian, saw Serbia's war against Austria-Hungary as a "war of liberation" that would "free South Slavs from tyranny." In his own words: "If ever there was a battle for freedom, there is such a battle now going on in Southeastern Europe against Austrian and Magyar. If this war ends in the overthrow of the Magyar tyranny, an immense step forward will have been taken toward racial liberty and European peace." 1914 Prior to 1914, the Russian's lack of success in war and diplomacy in the six decades before 1914 sapped the country's moral strength. The triumphs of Britain and Germany in the martial, diplomatic and economic spheres put these countries in
