The First World War

The First World War began with the assassination of Archduke Franz Ferdinand in Sarajevo on June 28, 1914, by Serbian terrorists. This act of terrorism, targeting the heir to the Austro-Hungarian throne, was seen as a grave offense, especially given the precarious state of the Austro-Hungarian Empire and the significance of a perpetual ruler. The assassination occurred in Bosnia, a region with a complex ethnic mix and Serbian discontent under Austrian rule. Austria-Hungary, convinced of Serbian government complicity, was determined to punish Serbia.

A crucial factor was the existing alliance system. Serbia, though small, had a powerful protector in Russia, sharing Slavic and Orthodox ties. Austria-Hungary, in turn, was allied with Germany, a rising global power. Germany, led by Kaiser Wilhelm, assured Austria-Hungary of its full support, even if Russia intervened, making a critical miscalculation that Russia would not dare to get involved. This 'blank cheque' from Germany, given by the Kaiser without consulting parliament, reflected the confidence of military and industrial leaders like General von Moltke and Alfred Krupp, who believed Germany was ready for war but that its actions would not trigger a wider conflict.

Pre-1914 Europe was economically prosperous and interdependent, yet nations were heavily armed due to mutual fear and Darwinian ideologies emphasizing the survival of the fittest. This period saw an arms race, with countries like France extending conscription. Despite a few voices warning of a catastrophic war (e.g., Norman Angell's "The Great Illusion"), military leaders across Europe were preparing detailed war plans. German generals, for instance, had meticulously planned for a swift victory over France and Russia, including invading neutral Belgium, confident in their military readiness. This created a paradox: politicians saw an impending catastrophe, while military leaders saw an opportunity that would only improve with an early strike.

Austria-Hungary, pressured by Germany, issued a harsh ultimatum to Serbia on July 23, 1914, designed to be rejected. Europe reacted with alarm, particularly Russia, which began preliminary mobilization. Britain, initially ambivalent, began to take notice as its naval minister, Winston Churchill, alerted the fleet. Germany's chancellor warned Russia against mobilization, insisting it would trigger war, yet Russia ordered general mobilization on July 30. The Kaiser, initially relieved by Serbia's moderate reply, was forced to accept Austria's declaration of war on Serbia on July 28 amidst popular enthusiasm for punitive action against Serbia. This period saw frantic telegrams between Tsar Nicholas ('Nicky') and Kaiser Wilhelm ('Willy'), first cousins, highlighting their personal efforts to avert war, though ultimately failing.

A critical turning point was Germany's strategic decision to invade neutral Belgium to attack France, as outlined in the Schlieffen Plan. On July 29, Germany attempted to guarantee Britain that it had no territorial ambitions in France and would evacuate Belgium after the war, but this only alarmed Britain. The British foreign minister, Grey, warned that Britain would not stand aside if war erupted and that German aggression was comparable to Napoleon's. Germany's insincerity was evident, and Britain, which had guaranteed Belgian neutrality, began to shift towards intervention. The refusal of Germany to respect Belgium's neutrality solidified Britain's resolve, leading to Grey securing parliamentary authorization for an ultimatum to Germany. When Germany invaded Belgium on August 4, Britain declared war. The conflict, initially localized, rapidly spiraled into a global war due to a series of inflexible military plans, mutual distrust, and fatal diplomatic miscalculations.
