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:

    If the world would only build temples to Machinery in the abstract then everything would be perfect. The painter and sculptor would have plenty to do, and could, in complete peace and suitably honoured, pursue their trade without further trouble.
    Wyndham Lewis (1882–1957)

    [Veterans] feel disappointed, not about the 1914-1918 war but about this war. They liked that war, it was a nice war, a real war a regular war, a commenced war and an ended war. It was a war, and veterans like a war to be a war. They do.
    Gertrude Stein (1874–1946)
