First World War

The First World War, also known as World War I, lasted from 1914 to 1918 and involved many of the world's great powers, divided into two main alliances: the Allies and the Central Powers. It began after the assassination of Archduke Franz Ferdinand of Austria-Hungary, leading to widespread conflict due to existing tensions and alliances. The war was characterized by trench warfare, significant battles, and massive loss of life. It ended with the Treaty of Versailles, reshaping borders and societies. The war had lasting impacts, setting the stage for future conflicts, particularly World War II.
