World War

A world war is a war affecting most of the world's most powerful and populous countries. World wars span multiple countries on multiple continents, with battles fought in multiple theaters.

The term is usually applied to the two conflicts of unprecedented scale that occurred during the 20th century: World War I (1914–1918) and World War II (1939–1945). However, it is also sometimes applied to earlier wars and to a hypothetical future war.

Famous quotes containing the words world and/or war:

    This world is run by people who know how to do things. They know how things work. They are equipped. Up there, there’s a layer of people who run everything. But we—we’re just peasants. We don’t understand what’s going on, and we can’t do anything.
    Doris Lessing (b. 1919)

    Only in war are you holy, and when you are robbers and cruel.
    Friedrich Nietzsche (1844–1900)
