Most Significant Wars In Human History

The Top Ten
1 World War II
2 World War I

I vote ww1 over ww2 because the first world war set the stage for the second one. Without it ww2 and many wars after wouldn't have happened.

3 Napoleonic War
4 Seven Years War
5 American Revolution
6 Thirty Years War
7 German Wars of Unification
8 American Civil War

Over 300,000 Northern soldiers were killed in the successful effort to eradicate slavery, and keep the Union together.
