WORLD HISTORY

Detailed explanation-1: -The main causes of World War 1 were alliances between countries, militarism, nationalism, imperialism, secret diplomacy, and internationalism. The assassination of Archduke Franz Ferdinand, heir to the throne of Austria-Hungary, by Gavrilo Princip in Bosnia is widely accepted as the starting point for World War I.

Detailed explanation-2: -Though their significance is often misunderstood or exaggerated, alliances are one of the best-known causes of World War I. While alliances did not force nations to war in 1914, they nevertheless drew them into confrontation and conflict with their neighbours.

Detailed explanation-3: -European Expansionism The expansion of European nations as empires (also known as imperialism) can be seen as a key cause of World War I, because as countries like Britain and France expanded their empires, it resulted in increased tensions among European countries.

Detailed explanation-4: -World War I, also known as the Great War, began in 1914 after the assassination of Archduke Franz Ferdinand of Austria. His murder catapulted into a war across Europe that lasted until 1918.

Detailed explanation-5: -Nationalism was a particularly important cause of World War I due to several key factors. For instance, it caused nations to build up their armies and led to increased militarism. As well, it created extremely high tensions in Europe in the decades before the outbreak of the First World War.
