Nationalism is claimed to be one of the main causes of World War I. This article provides a critical analysis of the causal relationships between nationalism and World War I in different countries. The author found that the war was encouraged by elites and supported by the masses, but it did not emerge due to the rise of nationalism. He suggested that in most countries except for Germany and Japan, nationalism insignificantly impacted World War I as this correlation was weak worldwide (Mann, n.d.). Instead, the war mobilized populations and thus increased nationalism.
