World War I, also known as the Great War, was a global conflict that lasted from 1914 to 1918. The war was primarily fought between the Allied Powers, which included countries such as France, Russia, and the United Kingdom, and the Central Powers, which included Germany, Austria-Hungary, and the Ottoman Empire.
The war began in July 1914 with the assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist. This event triggered a series of alliances and treaties that led to a chain reaction of declarations of war between the major European powers.
The early stages of the war saw rapid advances and retreats on the Western Front, with both sides digging in and establishing trench warfare. The war also saw significant fighting on the Eastern Front, in the Middle East, and in other theaters of conflict.
Over the course of the war, new technologies such as tanks, airplanes, and chemical weapons were introduced, leading to unprecedented levels of destruction and casualties. The war also saw the mobilization of millions of soldiers and civilians, as well as the implementation of total war strategies by both sides.
The war came to an end in November 1918 with the signing of the Armistice of Compiègne, which led to the surrender of the Central Powers and the eventual signing of the Treaty of Versailles in 1919. The treaty imposed harsh penalties on Germany and its allies, leading to economic hardship and political instability in the years that followed.
Overall, World War I had a profound impact on the course of history, leading to the collapse of empires, the redrawing of national borders, and the rise of new ideologies and political movements. It also set the stage for the even deadlier conflict of World War II.
