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:

    There’s nothing in the world like the devotion of a married woman. It’s a thing no married man knows anything about.
    Oscar Wilde (1854–1900)

    The great war that broke so suddenly upon the world two years ago, and which has swept up within its flame so great a part of the civilized world, has affected us very profoundly.... With its causes and its objects we are not concerned. The obscure fountains from which its stupendous flood has burst we are not interested to search for or explore.
    Woodrow Wilson (1856–1924)
