World War I lasted from 28 July 1914 to 11 November 1918. It led to the mobilisation of more than 70 million military personnel. It is also one of the deadliest conflicts in history, with an estimated 9 million combatant deaths and 13 million civilian deaths as a direct result of the war. The resulting genocides and the related 1918 Spanish flu pandemic caused another 17–100 million deaths worldwide.
About World War I in brief

The Great War was won by the Allied Powers, with Germany losing the war in November 1918. The Allied Powers also won the Battle of the Bulge, which ended the conflict in May 1919. The Battle of Verdun, which began in June 1918, ended the war with the fall of the German Empire in May 1918. Germany won the war on the Western Front, and the Allies won the battle on the Eastern Front, which was won in October 1918. In November 1918, the Allies declared victory over the Germans, and Germany lost the war for the first time since the First World War. The conflict began after Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis. In response, Austria-Hungary issued an ultimatum to Serbia on 23 July. Serbia’s reply failed to satisfy the Austrians and the two moved to a war footing. A network of interlocking alliances enlarged the crisis from a bilateral issue in the Balkans to one involving most of Europe. By July 1914, Europe were divided into two coalitions: the Triple Entente, consisting of France, Russia, and Britain; and the Triple Alliance of Germany,. The Triple Alliance was only defensive in nature, allowing Italy to stay in the war until April 1915, when it joined the Allies.
