World War I had a dramatic effect on nations and peoples
throughout the world. In Europe, it led to the collapse
of venerable empires and the emergence of several
new nations based on the ambiguous principles of nationalism.
In Asia, it spurred the rise of nationalist movements
dedicated to freeing their societies from the ravages
of Western colonialism. In Russia, it produced a
cataclysmic revolution based on a new ideological paradigm
that presented a mortal threat to the core principles
of the Enlightenment. European rulers who had opted for
war in 1914 to pursue their own dreams of national
grandeur had reaped a whirlwind that would soon bring
an end to a century of European domination over world
affairs.
Optimists had hoped that the bitter experience of a
bloody conflict would usher in a new world “safe for democracy.”
The reality was otherwise. The Great Depression
of the 1930s undermined worldwide confidence in
the capacity of the capitalist system to sustain modern
progress even as it sowed the seeds of a second global
conflict far more destructive than the first. It is to that
devastating conflict that we must now turn.
