Nationalism as a cause of World War I

Nationalism is an extreme form of patriotism or loyalty to one’s country. Nationalists place the interests of their own country above those of other countries. Nationalism was prevalent in early 20th century Europe and became a significant cause of World War I. Most pre-war Europeans believed in the cultural, economic and military supremacy of their nation. Their attitudes and over-confidence were fuelled by things like provocative speeches or press reports. The pages of newspapers were often packed with nationalist rhetoric and inflammatory stories, such as rumours about rival nations and their evil intentions. Nationalism was also present in other aspects of popular culture, including literature, music and theatre. Royals, politicians and diplomats did little to deflate nationalism – and some actively contributed to it with provocative remarks and rhetoric.




Nationalism also gave citizens inflated confidence in their nation, their governments and their military strength. It assured them that their country was fair, righteous and without blame. In contrast, nationalist ideas demonised rival nations, caricaturing them as aggressive, scheming, deceitful, backward or uncivilised. Nationalist reporting convinced many that their country was being threatened by the plotting, scheming and hungry imperialism of its rivals. Nationalist and militarist rhetoric assured them that if war erupted, their nation was destined to be victorious. In concert with its dangerous brothers, imperialism and militarism, nationalism contributed to a continental delusion where a European war seemed both necessary and winnable.

“A new and aggressive nationalism, different from its predecessors, emerged in Europe at the end of the 19th century… The new nationalism engaged the fierce us/them group emotions – loyalty inwards, aggression outwards – that characterise human relations at simpler sociological levels, like the family or the tribe. What was new was attaching these passions to the nation… In its outward-looking dimension, the new nationalism was fully a movement of the ‘age of imperialism’ – of the ‘great game’, the ‘scramble for Africa’, the enterprise of great powers.”
Lawrence Rosenthal, historian

Europe’s apathy about the dangers of war can be explained. Aside from the Crimean War (1853-56) and the Franco-Prussian War (1870-71), the 19th century was one of comparative peace in Europe. Citizens of England, France and Germany had grown accustomed to colonial wars: conflicts fought against undeveloped and underequipped opponents in faraway places, that were usually brief and victorious. With the exception of France, which was defeated by the Prussians in 1871, none of Europe’s Great Powers had experienced a significant military defeat for more than half a century. Along with rising militarism and the burgeoning arms race, this fostered a growing delusion of invincibility. The British, for example, believed their naval power and the economic might of the Empire would give them the upper hand in any war.

The Germans placed great faith in Prussian military efficiency, their growing industrial base, new armaments and an expanding fleet of battleships and U-boats (submarines). In the event of war, the German high command had supreme confidence in the Schlieffen Plan, a preemptive military strategy for defeating Germany’s eastern and western neighbours: Russia and France. In Russia, the tsar believed his throne and empire were protected by God – not to mention Russia’s massive standing army of 1.5 million men, the largest peacetime land force in Europe. Russian commanders believed the empire’s enormous population gave it the upper hand over the smaller nations of western Europe. The French placed their faith in a wall of concrete fortresses and defences, running the length of their eastern border, capable of withstanding any German attack.

By the late 1800s, some European powers had grown almost drunk with patriotism and nationalism. Britain, to focus on one example, had enjoyed two centuries of imperial, commercial and naval dominance. Britain’s empire spanned one-quarter of the globe and the lyrics of a popular patriotic song, Rule, Britannia!, trumpeted that “Britons never never will be slaves”. London had spent the 19th century advancing her imperial and commercial interests and avoiding wars – however, the unification of Germany, the speed of German armament and the bellicosity of Kaiser Wilhelm II caused concern among British nationalists. England’s ‘penny press’ – a collective term for cheap serialised novels – fuelled foreign rivalries by publishing incredible fictions about foreign intrigues, espionage, future war and invasion. The Battle of Dorking (1871), one of the best-known examples of ‘invasion literature’, was a wild tale about the occupation of England by German forces. By 1910, a Londoner could buy dozens of tawdry novellas warning of German, Russian or French aggression. This invasion literature often used racial stereotyping or innuendo: the German was depicted as cold, cruel and calculating; the Russian was an uncultured barbarian; the Frenchman was a leisure-seeking layabout; the Chinese were a race of murderous, opium-smoking savages. Penny novelists, cartoonists and satirists mocked the rulers of these countries. Two of the most popular targets were the German Kaiser and the Russian tsar, both of whom were ridiculed for their arrogance, ambition or megalomania.

German nationalism and xenophobia were no less intense, though they came from different origins. Unlike Britain, Germany was a comparatively young nation: it was formed in 1871 through the unification of 26 German-speaking states and territories. German nationalism, or ‘Pan-Germanism’, was the political glue that bound these states together. The leaders of post-1871 Germany relied on nationalist sentiment to consolidate and strengthen the new nation and to gain public support. German culture – from the poetry of Goethe to the music of Richard Wagner – was promoted and celebrated. German nationalism was backed by German militarism; the state of the nation was defined and reflected by the strength of its military forces. The new Kaiser, Wilhelm II, was the personification of this new Germany. Both the Kaiser and his nation were young, nationalistic, obsessed with military power and imperial expansion. The Kaiser was proud of Germany’s achievements but nervous about its future; he was envious of other powers and desperate for national success. In the kaiser’s mind, the main obstacle to German expansion was Britain. Wilhelm envied Britain’s vast empire and enormous naval power – but he thought the British avaricious and hypocritical. The British government oversaw the world’s largest empire yet manoeuvred against German colonial expansion in Africa and Asia. The British became a popular target in the pre-war German press, where Britain was painted as expansionist, selfish, greedy and obsessed with money. Anti-British sentiment intensified during the Boer War of 1899-1902, Britain’s war against farmer-settlers for control of South Africa.

As the Great Powers beat their chests and filled their people with a sense of righteousness and superiority, another form of nationalism was on the rise in southern Europe. This nationalism was not about supremacy or military power – but the right of ethnic groups to independence, autonomy and self-government. With the world divided into large empires and spheres of influence, many different regions, races and religious groups wanted freedom from their imperial masters. In Russia, more than 80 ethnic groups in eastern Europe and Asia were forced to speak the Russian language, worship the Russian tsar and practice the Russian Orthodox religion. For much of the 19th century China had been ‘carved up’ and economically exploited by European powers; resentful Chinese formed secret and exiled nationalist groups to rid their country of foreign influence. Nationalist groups contributed to the weakening of the Ottoman Empire in eastern Europe, by seeking to throw off Muslim rule.

No nationalist movement had a greater impact on the outbreak of war than Slavic groups in the Balkans. Pan-Slavism, the belief that the Slavic peoples of eastern Europe should have their own nation, was a powerful force in the region. Slavic nationalism was strongest in Serbia, where it had risen significantly in the late 19th and early 20th centuries. Pan-Slavism was particularly opposed to the Austro-Hungarian Empire and its control and influence over the region. Aggravated by Vienna’s annexation of Bosnia and Herzegovina, young Serbs joined radical nationalist groups like the ‘Black Hand’ (Crna Ruka). These groups hoped to drive Austria-Hungary from the Balkans and establish a ‘Greater Serbia’, a unified state for all Slavic people. It was this pan-Slavic nationalism that inspired the assassination of Archduke Franz Ferdinand in Sarajevo in June 1914, an event that led directly to the outbreak of World War I.

1. Nationalism was an intense form of patriotism. Those with nationalist tendencies celebrated the culture and achievements of their own country and placed its interests above those of other nations.

2. Pre-war nationalism was fuelled by wars, imperial conquests and rivalry, political rhetoric, newspapers and popular culture, such as ‘invasion literature’ written by penny press novelists.

3. British nationalism was fuelled by a century of comparative peace and prosperity. The British Empire had flourished and expanded, its naval strength had grown and Britons had known only colonial wars.

4. German nationalism was a new phenomenon, emerging from the unification of Germany in 1871. It became fascinated with German imperial expansion (securing Germany’s ‘place in the sun’) and resentful of the British and their empire.

5. Rising nationalism was also a factor in the Balkans, where Slavic Serbs and others sought independence and autonomy from the political domination of Austria-Hungary.
