Hello! World War I, also known as the Great War, took place from 1914 to 1918. The conflict involved major powers, including the Allies (France, Russia, and later joined by the United Kingdom and others) and the Central Powers (Germany, Austria-Hungary, and the Ottoman Empire). The war was triggered by a complex web of political, economic, and militaristic factors, including the assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914. Key events include trench warfare on the Western Front, battles like the Somme and Verdun, and the use of new technologies such as tanks and chemical warfare. The United States joined the Allies in 1917, contributing to their eventual victory. The war led to significant geopolitical changes, including the collapse of empires, the redrawing of borders, and the League of Nations' establishment in an attempt to prevent future conflicts. The Treaty of Versailles in 1919 officially ended World War I, imposing harsh terms on Germany and setting the stage for future geopolitical tensions.
