2. The 20th Century Begins
As the 20th century opened, Europe was brimming with tension. On the surface, all appeared calm. But underneath, the forces of nationalism, imperialism, and militarism helped fuel an intense competition among European nations. In 1914, these forces—along with a set of complex military alliances—led to a war that engulfed all of Europe and eventually touched nearly every corner of the world.
After four years of fighting, the Allied Powers, led by France, Britain, and the United States, defeated the Axis (or Central) Powers, comprised mainly of Germany and Austria-Hungary. The conflict, which saw the first use of so much advanced weaponry, devastated Europe. The war left millions dead and millions more wounded. It also left behind a peace treaty that only increased many nations’ bitterness toward one another.
