mobilization of an army was considered what in 1914
Mobilization Intricate plans for mobilization contributed greatly to the beginning of World War I, since in 1914, under the laws and customs of warfare then observed (not to mention the desire to avoid compromising national security), general mobilization of one nation's military forces was invariably considered an act of war by that country's likely enemies.
World War I Between 1908 and 1914, the Balkans had been destabilised by the combination of a weakened Ottoman Empire, the 1912–1913 Balkan Wars and competing Russian and Austro-Hungarian objectives.[13] On 28 June 1914, Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis.[14][15] On 23 July, Austria-Hungary issued an ultimatum to Serbia; interlocking alliances quickly drew in all the major European powers with their respective colonial empires and the conflict rapidly spread across the globe.
