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:
“We don’t know any more about pictures than a kangaroo does about metaphysics.... To us, the great uncultivated, it is the last thing in the world to call a picture. Brown said it looked like an old fire- board.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The war shook down the Tsardom, an unspeakable abomination, and made an end of the new German Empire and the old Apostolic Austrian one. It ... gave votes and seats in Parliament to women.... But if society can be reformed only by the accidental results of horrible catastrophes ... what hope is there for mankind in them? The war was a horror and everybody is the worse for it.”
—George Bernard Shaw (1856–1950)
