World War I

World War I, also known as the Great War, was a global conflict that lasted from 1914 to 1918. It primarily involved the Allied Powers, including countries like France, the United Kingdom, Russia, and later the United States, against the Central Powers, which included Germany, Austria-Hungary, and the Ottoman Empire. The war was characterized by trench warfare, significant technological advancements in weaponry, and massive military engagements. It was triggered by a complex web of alliances and the assassination of Archduke Franz Ferdinand of Austria. The conflict led to significant political, social, and economic changes worldwide, including the collapse of empires and the redrawing of national boundaries. World War I resulted in an estimated 16 million deaths and left deep scars in many nations, influencing future geopolitical landscapes and setting the stage for World War II due to unresolved tensions and resentments. The Treaty of Versailles in 1919 formally ended the war, imposing heavy reparations and territorial losses on Germany, which would contribute to future conflicts.
