What is the legacy of wwi

World War One completely changed the outlook on war it used to be noble and happy thing for most people like during the civil war people would go and watch the people fight but World War One exposes War for what it really is an evil and deadly thing that people before hand never really noticed

Answer:The war destroyed four empires - the German, Russian, Austro-Hungarian, and Ottoman - and redrew the political map of the world. The new nations and borders created after the war sowed the seeds for new conflicts in the Baltics, the Balkans, Africa, and throughout the Middle East, many of which ravage the world today.
