World War I is a world war, a global armed conflict that developed primarily in Europe from July 28, 1914 to November 11, 1918, in which 38 states with a population of 1.5 billion took part.

By July 1914, the great powers of Europe were divided into two coalitions: the Triple Entente, consisting of France, Russia, and Great Britain; and the previously established Triple Alliance of Germany, Austria-Hungary, and Italy. The Triple Alliance was only defensive in nature, allowing Italy to stay out of the war until April 26, 1915, when it joined the Allied Powers after the deterioration of its relations with Austria-Hungary. The Russian Empire considered it necessary to support Serbia and approved partial mobilization after Austria-Hungary shelled the Serbian capital Belgrade, which was located a few kilometers from the border, with artillery on July 28, 1914.
