History
An overview of World War I (1914-1918), the global conflict that reshaped nations, societies, and the very nature of warfare forever.
World War I, also known as the Great War, was a global conflict that lasted from July 28, 1914, to November 11, 1918. It involved the Central Powers—primarily Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria—fighting against the Allied Powers, which included Great Britain, France, Russia, Italy, Japan, and later the United States. The war was triggered by the assassination of Archduke Franz Ferdinand of Austria. It was marked by brutal new military technologies and the horrors of trench warfare, leading to unprecedented levels of destruction and more than 16 million deaths of soldiers and civilians alike.
World War I remains a pivotal and frequently studied topic because it was a major turning point in 20th-century history. It led to the collapse of four great empires: the German, Austro-Hungarian, Russian, and Ottoman. This collapse resulted in a complete redrawing of the map of Europe and the Middle East, creating many new nations. The war's conclusion and the controversial Treaty of Versailles are seen as direct contributors to the circumstances that led to World War II. Its influence on modern warfare, politics, and global consciousness continues to be analyzed by historians.
The war had a devastating and lasting impact on societies worldwide. It caused the death of an entire generation of young men, leaving millions more physically and psychologically wounded. The conflict spurred significant social changes, including new opportunities for women in the workforce, which advanced the cause of women's suffrage. Economically, it ravaged European nations, leading to immense debt and the rise of the United States as a leading world power. The war's aftermath also fueled independence movements in European colonies and led to major political transformations and unrest in many countries.
